    Opis:
    Although the number of publications on gully erosion has increased over the last decade, there are still various aspects of gully erosion that deserve more research efforts. Some of these, discussed in this contribution, are gully erosion in historical times, measuring techniques, processes of gully initiation, development and infilling, the interaction between gully erosion with hydrological and other soil degradation processes (e.g. piping, landsliding, tillage erosion and erosion induced by land levelling), gully erosion models, effective and efficient gully prevention and control measures. A better understanding of these aspects would allow one to better predict the impact of environmental change, gully prevention and control measures on gully erosion and gully infilling rates at a range of temporal and spatial scales and for various types of environments, and the effects of gully erosion on sediment yield, hydrological process intensities and landscape evolution.

    Sandomierz Upland
    Opis:
    The development of the side arm edge of the valley-gully in Gałkowice village in the Dwikozy commune (the Opatówka catchment in the Sandomierz Upland) was investigated during the period from 2002 to 2017. An increase of fragmentation of the gully edge was found. Most of the pre-existing erosive indents increased in size (maximum of 2.8 m – about 0.2 m per year). An increase in the area of the gully by 145 m2 was found. As a result, the boundary of plow tillage shifted to an average of 1.5 to 2 meters (maximum 3.8 m), which resulted in a loss of 545 m2 of adjacent arable land. As the main reason for the development of the analyzed section of the gully, meltwater flows were considered.

    Opis:
    The paper contains analysis of the anti-erosion system in the road gully in Wielkopole, Lublin Upland. The solution implemented in the gully’s bottom is effective against line erosion – there is no gully deepening. Lack of protection of slopes results in an intense earthmass movements. At the brim zone of the gully suffosion processes occur leading to the gully widening. The eroded material is accumulated on the road and colmatage drainage system of voivodship road no. 842, what is dangerous to traffic and generates expenses. That is why anti-erosion systems should be implemented comprehensively, protecting both the slopes and the bottom of gullies. Projects of such systems should be consulted with specialist.

    Opis:
    Accurate morphological parameters are key to understand the process and mechanism of gully erosion, but little information exists regarding the accuracy of gully volume influenced by sampling spacing. In order to assess the influence of sampling spacing on volume of medium gully under the condition of different shapes of gully cross-sections, as well as to provide information for proposed surveys, a MultiStation was utilized to obtain the point cloud of a Uand V-shaped gully. The coordinates were subsequently rarefied to a certain sampling spacing, and the gully volumes of three modes (Mode 1 only including rarefied terrain points; Mode 2 including detailed terrain and rarefied terrain points; Mode 3 including the rarefied detailed terrain points and terrain points with a given sampling spacing) were calculated in ArcGIS. The results showed that the error of gully volume increased non-monotonously with sampling spacing increased, and that the detail points had greater influence on the gully volume of a U-shaped than a V-shaped gully. As to Mode 1 and 2, the relative error (RE) of U-shaped gully volume increased faster with sampling spacing increasing, and presented high positive correlation. However, in the case of a V-shaped gully, a middle positive correlation for Mode 1 can be observed, and the RE was below 3% for Mode 2. For Mode 3, an increase in the sampling spacing of the terrain led to the larger RE, average RE, and variance of absolute error. If extremely high accuracy (2.5% of RE) is required, sampling spacing is less than 0.5 m; if high accuracy (5% of RE) is set, the sampling spacing of terrain points is below 0.8 m for a U-shaped gully, while the corresponding sampling spacing of terrain points and detail points are 2.0 m and 1.85 m, 3.0 m and 1.80 m, and 4.0 m and 0.75 m for a V-shaped gully. The shape of the gully’s cross-section, as well as the exact location of the shoulder line will affect the accuracy of the gully’s volume. This study will increase the efficiency of detail survey in the field for medium gully.

    The aim of this paper is to present a characteristic of loess permanent gullies, which form the branched erosion system, with the total length of almost 7.8 km, dissecting an erosion-denudation dry valley. Only 20%of the gully system catchment is cultivated as the result of steep slopes and considerable height differences up to 100 m. 80%of the catchment is covered by fir coniferous forest and Carpathian beech forest, and gully development is the result of intensive forest exploitation. Five types of gullies have been selected on the basis of the runoff directions, which are determined by the following: original relief, runoff concentration from fields, runoff concentration from fallplaces, skidding and course of forest roads used to carry a timber.

    Opis:
    The study describes the gully system in the Rogów area (Lublin Upland). Based on field researchand available literature, four stages of gully erosion and three stages of alluvial sediment deposition were identified. The first erosion stage occurred towards the end of the last glacial period and was determined by natural factors. The other three erosion stages occurred in the Holocene and were impacted by man’s agricultural activity.

    Opis:
    Large catchment basins (the Yenisei, Angara, Lena, Selenga, and Amur) within southern East Siberia are characterized by weak gully dissection, and by a very uneven distribution of gullies.The varied natural conditions, combined with anthropogenic impacts, produce a highly mosaic pattern in the spatial distribution of gullies.For the last 230-300 years, four intensification stages of gully erosion were identified, which were associated with periods of abrupt changes in nature management.The growth rates of the gully heads in different areas of southern East Siberia vary from 0.1 to 26 m yr-1, the mean long-term linear growth rates of gullies are 0.5–2.5 m yr-1.Extreme meteorological phenomena: torrential rains (over 30 mm hr-1), abundant rains (over 50 mm day-1), and rapid snow thawing in the spring are responsible for gullying.

    Opis:
    Spindle-shape in form the Pereschiv catchment is located in the Tutova Rolling Hills, Southern Moldavian Plateau, and covers 23,267 ha. Based on both the aerial photos and field data a number of 847 gullies, stretching on 512 ha (2.20% of the total) have been identified. Of this gullied area, 34.5% (177 ha) is under 737 valley-side gullies, while 65.5% (335 ha) is under 110 valley-bottom gullies. As for 54 representative valley-bottom gullies by comparing their present state with the previous one, derived from topographical maps (based on successive aerial flights from 1960, 1962, 1974, 1977, 1981), it was possible to estimate gullying indicators, such as gully-head advance and areal gully growth. Finally, the gully erosion rate was estimated at 9.8 t ha-1 yr-1 that represents 56% of the total erosion within the study area.

    A GIS+analysis was carried out in a test basin of southern Sicily, the Magazzolo River basin, in order to assess susceptibility conditions to gully erosion phenomena. The linear density of ephemeral and permanent gullies computed within each class of nine environmental variables was used to generate a gully erosion susceptibility map for the area. A validation procedure carried out in order to test the reliability of the adopted method highlighted a clear correlation between the occurrence of gullies and the computed susceptibility levels.

    Pikes Peak Highway is a partially paved road between Cascade, CO and the summit of Pikes Peak (4300 meters). Significant gully erosion is occurring on the hillslopes due to the concentration of surface runoff along the road surface and adjacent drainage ditches. As a result, large quantities of sediment are transported to the surrounding valley stream networks causing significant damage to riparian, wetland, and aquatic environments. This study addresses the rates of gully erosion along the Pikes Peak Highway.

    Opis:
    Badania wykonano w umocnionych wąwozach w Opoce Dużej, gdzie w latach 1962–1964 wykonano przeciwerozyjną zabudowę biotechniczną. Na podstawie badań można stwierdzić, że zastosowana zabudowa wąwozów okazała się skuteczna. Wąwozy nie pogłębiły się i nie powiększyły swoich rozmiarów, a koryto Sanny nie wymagało kosztownego bagrowania. Na dnach wąwozów obserwuje się głównie akumulację materiału glebowego. W ciągu 51 lat na dnach wąwozów osadziło się około 4000 m3 namułów. Budowle hydrotechniczne skutecznie utrwaliły progi erozyjne i dno wąwozu przed erozją liniową oraz przyczyniły się do zatrzymania żyznego materiału glebowego, dzięki czemu powstały korzystniejsze warunki dla wzrostu roślinności. Jednak stosowanie tego typu budowli w wąwozach powinno być ograniczone do niezbędnego minimum ze względu na wysoki koszt zatrzymania m3 materiału ziemnego oraz wprowadzanie sztucznych elementów w krajobraz.
    The studies were carried out in consolidated gullies in Opoka Duża, an anti-erosion biotechnical structure created in 1962–1964. On the basis of the studies it can be stated that the applied gullies buildings appeared to be efficient. Gullies did not deepen and did not increase its dimensions, whereas the Sanna river bed did not require expensive dredging. Accumulation of soil material is mainly observed at the bottoms of the gullies. In 51 years, about 4000 m3 of material accumulated at the bottoms. Hydrotechnical structures efficiently strengthened the erosion thresholds and bottoms of gullies against linear erosion and contributed to the inhibition of the fertile soil material creating more favourable conditions for plants growth. However, application of this type of buildings in gullies should be reduced to a necessary minimum, due to the high cost of maintaining a m3 of soil material and the introduction of additional elements in the landscape.

    Opis:
    Five complex soil profiles in gully system on Nałeczów Plateau (E Poland) were examined. They represent the loess sediments modified by soil processes and postpedogenic transformations. Two examined profiles represent natural and mature Luvisols with diagnostic illuvial horizon (Bt argillic) developed on the edge of plateau geomorphologic level and in the relict valley bottom. The other soil profiles reflects postpedogenic soil degradation, redeposition and secondary accumulation (deluvia, colluvia and/or proluvia). Record of these processes are the micromorphological features created by lithological processes (=primary loess and secondary pedoliths) or by pedogenesis (mainly bioturbation, illuviation, de- and recalcification). The important group of microfeatures are pedorelicts which clearly confirm genetic dependences of pedoliths (deluvia and proluvia) and soils developed in situ and located in higher hypsometric levels in the catchment.

    In south-eastern Latvia many old gullies can be found, however, few studies hitherto have reported on their morphology and factors controlling their genesis. This paper presents results of the research covering morphometry, morphology and classification of gullies, the paleogeographic reconstruction of environmental conditions and factors that led to development of these erosion landforms in the river Daugava Valley. Obtained results permits to distinguish five morphogenetic types of gullies, which differ by topographic characteristics, shape of cross-profile, time of formation, and genesis. Simultaneously, presence of different types of gullies in the case study area geomorphologically reflects several incision-accumulation cycles of the erosion network development.

A program for controlling gully erosion was carried out in Heshan Farm in black soil region of northeast China from 1994 to 1996 include two approaches: "Soil fill" and "Vegetation cover". From the investigation at 2009, Soil fill approach can protect the original place of gully erosion well, but this apporach ignores the whole impact at the catchment scale, and may cause to new gully appear. "Vegetation cover" approach is better to control gully erosion than "Soil fill" approach, but has little effect on controlling the headcut retreat.

    Opis:
    The present study approaches gully erosion in Tutova basin (south-central part of the Moldavian Plateau, Eastern Romania), mainly with the help of GIS and remote sensing by using the TNTmips 7.3. software. For this purpose a GIS was created, that integrates the Digital Elevation Model, geologic and morphometric maps, climatic and soil data, land use information and others. The assessment of risks associated to gullying has monitored several indicators, grouped as follows: gully-head advance and probability of affecting objectives located upstream; dynamics of gully banks; areal gully growth and loss of agricultural land; flooding and sedimentation of the land or social and economical objectives situated downstream the gully.

    Loess areas are highly affected by human impact since the Neolithic revolution. Within the study in Małopolska we assess the impact of land-use changes on geomorphological processes for the last 200 years. Phases of deforestation and a subsequent intensive agricultural use can be correlated with the appearance of gully erosion.

    Opis:
    Comparison of commonly acting gullying and muddy floods at present (in the post-collectivization period) and in the past (mostly in the period of the 16th to 19th centuries) has showed considerable disparities; they are conditioned by the character of land use and climate changes, mostly in the case of their synchronous occurrence what has profoundly multiplied their geomorphic response.In the case when extreme events occur in the area with permanent, historical gullies, the current common operation of gully erosion and muddy floods can show similar features with their acting in the past.In such cases the material of muddy floods is coming not only from fresh ephemeral gullies but also from old permanent gullies that were deepened during these events.It was confirmed during extreme events that happened in cadastral areas of two villages in western Slovakia in 2009 that were not comparable with geomorphic effects of other events within the last period.

    The study was focused on the alluvial fans formed in the bottom of the Bystra river valley. A detailed analysis of four fans allowed to distinguish several phases of gully erosion related to human activity. The gullies started to develop in the Neolithis times, the subsequent phases of gully erosion could be dated to: Bronze Age, Middle Ages. In modern times, most of the sediments have been retained within the extensive gully systems.

    Opis:
    The results of investigations ascertain the influence of the water level regime on the erosion dynamics that was estimated according gullies volume change within the space-time between two measurements. The development of gullies in the shore zone is to a large extent influenced by the abrasion of shore slopes, which is intense at high water level in the reservoir. The minimum rate of gully development (4.5-54.7m3 yr-1) was due to the action of shore abrasion and eolian processes within the period of 2004-2007. A large positive dynamics can be attributed to the increasing number of erosion cuts. The maximum material loss from gullies (in total 627.66 m3 ) and the average volumetric retreat rate for all gullies (16.5 m3 yr-1) were recorded at the permanent lowering of the reservoir water level during the 2007-2008 period. Water level fluctuations cause cyclic changes in the dynamics of processes and initiate the new mechanism of erosion that is not typical of regular conditions.

    Study of sediments at gullies mouths conducted in the Suwałki Lakeland (NE Poland) showed that fan sediments are significantly diversified. The changes of sediment type could be linked to forest clearance and farmland expansion. Dating and lithological properties of fan sediments allowed to determine the stages of gully erosion. The research also included studies of sediments accumulated within last 200 years in 6 small gully catchments of different degree of cultivation. Supply of the sediments derived from soil erosion to the gully fans was very limited in catchments where only 15% of the land was cultivated. This process was intensively active in catchments where cultivated land occupied 77% of the area.

    Several kinds of methodologies and techniques have been used indeed in order to monitor rill and gully erosion processes. In this paper authors provide a guidance regarding the available aerial photographs and orthophotographs for rill and gully erosion studies in Spain and covering the whole country. A set of 8 different series of aerial photographs and orthophotographs were located in Spain. Their characteristics were quite diverse, differing in scales, formats and resolution. Most of the photographs and orthophotographs proved, at least, to be suitable for their use in studies of permanent gullies, allowing the monitoring of medium and long-term erosion rates since 1945.

    Current soil erosion models do not solve the impact of gully erosion on the landscape changes but only its spatial distribution and intensity. Distributed process-based model SIMWE (Mitas & Mitasova 1998) and landscape evolution module (Burton et. al. 2010) was used for simulation of gully erosion consequences in GIS environment. The results of simulation within the assigned initiation condition in the past showed the real situation at the present time. Simulation process corresponded with the theoretical knowledge about gully development. Modification and combination of selected module procedure and of erosion model has shown the potential of the presented method to predict effectively the genesis of gullies.

    Opis:
    The gully erosion is the most serious environmental problem in Agulu-Nanka, Southeastern Nigeria. Present study focused on characterization of geo-environmental factor in the gully affected areas to prevent future problems. The study investigates geotechnical analysis and catchment management of gully erosion in Agulu - Nanka, Anambra State, Nigeria. The major objectives were: to provide geotechnical parameters and data (permeability, liquidity, plasticity, consistency, moisture content and compaction) of the soils available in Agulu Nanka, Anambra State. The method of data collection employed was through field work which involves the use of GPS to capture the coordinates of the gully sites and tape rule to measure the width, depth, and length of the gullies. GIS techniques were used in data analysis. A total of 14 gully sites were coordinated and mapped, the result reveals the gully erosion were dispersed with areas of Nanka/Oko having the highest concentration of gullies. The generation of gully characteristic map reveals that the gullies vary from area to area in relation to their lithology. The characteristic map (in meters) was classified into three parameters with 2.00-6.06 as Low, 6.06-8.89 as Medium, and 8.89-13.77 as High. The gullies with the highest depths were within the coordinates of N6220.9364, E7458.5948; N6228.6836, E7459.4048; N6311.6208, E74333.6612 with 52.96m, 47.32m and 45.18m respectively. The length of the gullies at the concentrated region stretched as far as 4.37km while the gully with the largest width covered a large space of 397.20m. The result indicate the need for incorporation of gully vulnerability, the areas require dire attention to arrest the menace of the erosion threats.

    Opis:
    Ephemeral gullies (EGs) are channels of different sizes refilled by tillage equipment normally used on farms. In this paper, the data-set collected from 1995 to 2007 in a wheat--ultivated area in Raddusa (Sicily, Italy), having a surface of almost 80 ha, were used to analyze the morphological characteristics of EGs. The measurements show an high temporal variability in EG characteristics. The EG measurements and the rill erosion measurements carried out in 15 plots located in the experimental "Sparacia" area (Sicily), demonstrated that a morphological similarity condition exists between rills and ephemeral gullies. The occurrence of step-pool structures in an EG occurring in the observation period in the same place allows to conclude that, in the considered environment, an ephemeral channel, such an EG, similarly to a stream, tends to reach a step-pool morphology as the structure that maximises its stability.

    Opis:
    The areaswith thick loess covers face the risk of intense soil erosion processes as well as gully erosion. The western part of the Nałęczów Plateau is especially prone to particularly high degree of intensive erosion among the region (denudation hazard. The density of the gully network reaches here up to 10 km/km2. The administrative area of Kazimierz Dolny is under extreme threat of severe consequences of erosion processes which appeared with high frequency and caused significant devastation of infrastructure not only on a national but maybe on a European scale as well. Geological conditions together with surface features favour intensive, secondary and anthropogenically conditioned erosion processes. Already in the historical sources there are mentions about the disastrous consequences of torrential rainfalls in the Kazimierz Dolny region. In such conditions the torrential rainfall waters flow quickly down the gully bottoms of considerable inclinations, concentrating on the bottom of Grodarz river valley. As a result it may lead to flooding or silting of crops, the roads may be destroyed or silted and the properties completely flooded. Taking into account the natural and cultural values of Kazimierz Dolny and its surroundings, as well as the presence of the Kazimierz Landscape Park it is necessary to take urgent steps in order to limit the threats considerably.

    Opis:
    Nawiązując do wyników badań peryglacjalnych niecek i dolin denudacyjnych, prowadzonych w okolicach Łodzi przez prof. H. Klatkową w latach 50. i 60. ubiegłego stulecia, w artykule przedstawiono holoceńską ewolucję wyżej wymienionych form denudacyjnych. Wyróżniono trzy najważniejsze etapy tej ewolucji: 1) wypełnianie niecek i dolin denudacyjnych deluwiami antropogenicznymi, 2) rozcinanie form vistuliańskich przez wąwozy, 3) przemiany rzeźby wąwozów oraz niecek i dolin denudacyjnych pod wpływem denudacji agrotechnicznej. Poruszono zagadnienie czynników warunkujących neoholoceńskie zmiany rzeźby suchych niecek i dolin, podkreślając rolę narastającej antropopresji i fluktuacji klimatu. W pracy określono bliżej wiek poszczególnych etapów przemian ukształtowania niecek i dolin denudacyjnych. Ich ewolucja rozpoczęła się u schyłku subboreału i trwała przez niemalże cały subatlantyk aż do współczesności, ze szczególnym nasileniem w średniowieczu. Przedstawiono także litologiczną charakterystykę neoholoceńskich osadów wypełniających niecki i doliny denudacyjne.
    Referring to the results of the research on periglacial dells and valleys conducted in the vicinity of Łódź by Professor H. Klatkowa in the 50s and 60s of the last century, the paper presents the Holocene evolution of the aforementioned denudation forms. Three main stages of this evolution have been identified: 1) filling of periglacial dells and valleys with anthropogenic delluvium, 2) fragmentation of Vistulian forms through gullies, 3) relief transformation of gullies and periglacial dells and valleys by tillage erosion. The issue of factors influencing the Neoholocene changes in the relief of dry dells and valleys has been addressed, emphasizing the role of increasing human impact and climate fluctuations. In this paper the age of the individual stages of the transformations of the periglacial dells and valleys have been identified. Their evolution began at the end of the Subboreal period and lasted almost entire Subatlantic period until the present time, with a particular intensity in the Middle Ages. Lithological characteristics of Neoholocene deposits filling the periglacial dells and valleys is also presented.

    Opis:
    Sedimentological and geochemical research carried out in North- West Mazovia, central Poland, allowed the determination of landscape transformation in relation to the history of human settlement. The types of sediments subject to analysis included palaeochannel filling, accumulation on the river floodplain and colluvial deposits. The absolute ages of sediments and their sedimentological features allow the conclusion that the first response to human activity in the area is recorded in the overbank deposits in the Skrwa River valley as a result of the Wielbarska Culture in 200-300 AD. Subsequently, fan accumulation at the mouths of gullies started around the 12th-13th centuries AD. Frequent changes of sediment properties have been observed since the early Middle Ages. The subsequent anthropogenic impact on homogenous deposits is recorded in increased heavy metal concentration in vertical geological profiles.

    Opis:
    Causes of dynamic development of a permanent gully dissected in sandy river valley side were presented in this paper. Road and field pattern change conditioned the gully forming during one downpour. A new pattern and crop structure caused fast surface flow on the side. Flow concentration along the road and balks causes dissections of gully escarpments and development of the gully branches.

    Opis:
    Gullies in the temperate zone are the products of linear erosion, piping and mass movements active mostly during heavy rains. On dominant role of one of those three co-operating processes decide the parameters of rainfalls and permability of substratum. The diversity of gullying depends also on the inherited relief and stage of development of gully forms. In the cultivated areas the formation of gullies is initiated also by cart-roads.

    Opis:
    This study investigates how medium-term gully-development data differ from short-term data, and which factors are responsible for their spatial and temporal variability. Eight actively retreating bank gullies situated in Spanish basin landscapes were monitored for up to 11 years with high-resolution aerial photographs using unmanned remote-controlled platforms. The results of planimetric and volumetric change analysis using GIS and photogrammetry systems show a high variability of annual gully retreat rates both between gullies and between observation periods. The varying influences of land use and human activities with their positive or negative effects on runoff production and connectivity appears to play the most important role in these study areas, both for short-term variability and medium-term difference in gully development. The study demonstrates the importance of capturing spatially continuous, high-resolution three-dimensional data for detailed gully monitoring. It also confirms that short-term data are not representative of longer-term gully development, but they are still required to understand the processes - particularly human activity at varying time scales - causing gully-erosion variability.

    Opis:
    The article presents the development of a small, midfield form of road, which cuts the side of a loessic valley. The contemporary shape of the surface was determined by GPS measurements (Leica System 500), set together in ArcView and ArcGIS. Changing of its position was determined by a field analysis of the construction of 50 profiles of the Luvisols with varying degrees of erosion or aggradation. Calculation and visualization were performed in the ‘Surfer’ program. The results are interpreted in the context of changes in the agrarian structure since the end of the 19th century. It was found that the development of erosional forms is associated with an intensive use, since the late 1930s, of the road traced at the end of 19th century. Significant rate of its cutting is also the result of earlier soil erosion, due to its agricultural use since the late Middle Ages. Until achieving the depth of about 1 m, the form was the shape of a trough, because the road also served as a zone of turning round during the cultivation of the adjacent transversal-slope fields. In the 1970s, after a change in cultivation mode, erosion took the form of a box-like section. The average annual rate of cutting into the deepest section increased from 2.5 to4 cm and the depth - to 1.8 m. These conclusions confirm the profile of deposits on the extended cone at the gully mouth at the valley bottom. Their lower series, with thickness of 1.7 m and a massive structure, are products of soil erosion accumulated for several hundred years. The laminated top series with thickness of 0.8 m is distinguished by CaCO3 content growing towards the surface. Its accumulation at a rate of 1.2 cm per year is the result of a deeper cutting of the road on the slope.

    W artykule przedstawiono wyniki badań geomorfologicznych parowu wykształconego na zboczach Basenu Unisławskiego w Uściu koło Chełmna oraz badań sedymentologicznych osadów występujących w jego dnie i na stożku napływowym. Formy te rozwinęły się w kilku etapach, co zostało udokumentowane wynikami badań cech strukturalno-teksturalnych osadów oraz datowań OSL. Badania te wykazały, że parów jest wykształcony w dnie peryglacjalnej doliny denudacyjnej z czasu późnego glacjału, która była następnie pogłębiona w młodszej fazie okresu atlantyckiego (ok. 6–5 ka BP).
    This paper presents results of geomorphological analysis of alluvial fan and gully situated on the slope of the Unisław Basin (Lower Vistula Valley) in Uść near Chełmno as well as results of sedimentological analysis of deposits in these forms. The gully and alluvial fan near Uść were developed in few stages which are confirmed by structural and textural properties of their sediments and by results of OSL dating. Studies have shown that gully was created in the bottom of the denudation valley from Late Glacial, that was deepened later in the younger phase of the Atlantic period (ca 6–5 ka BP).

    Opis:
    Soil erosion continues to be problematic financially and environmentally with the USEPA ranking sediment as one of the top ten pollutants of concern in the USA. One aspect of erosion often overlooked is the role of ephemeral gullies in terms of quantity of sediment produced and amount exported to nearby waterways. Current physically-based and empirical models are inadequate for predicting this type of erosion particularly at the watershed scale. A new methodology for predicting the quantity and location of sediment delivery was developed and tested via a case study. Aerial ephemeral gully erosion rates varied from 33.6 mton/km2 (0.15 U.S. tons/acre) in the Big Bear Creek basin to 88.4 mton/km2 (0.39 U.S. tons/acre) in the Middle Potlatch Creek basin representing 2.3 to 7.7% of the total surface sediment load. This information was used to develop a predictive Erosion Potential Index (EPI) that uses LANDSAT aerial imagery combined with readily available soils information and a digital elevation model to identify the most probably locations of ephemeral gully development. High resolution aerial imagery was used to quantify actual ephemeral gully locations which were then compared to the EPI predicted locations to verify the procedure. High resolution aerial imagery was also used to quantify the amounts of soil erosion from ephemeral gullies in basins of the Potlatch River system.
    W pracy przedstawiono nowa metodykę prognozowania wielkości i miejsc występowania erozji wąwozowej w skali zlewni, którą sprawdzono na podstawie badań przeprowadzonych na obszarze o łącznej powierzchni 736 km2, w sześciu zlewniach mniejszych cieków położonych w środkowej części zlewni rzeki Potlatch. W badaniach wykorzystano zdjęcia lotnicze wysokiej rozdzielczości oraz wyniki pomiarów terenowych parametrów morfologicznych krótkotrwałych wąwozów erozyjnych, na podstawie których stworzono bazę danych GIS. Uzyskane wyniki badań posłużyły do opracowania Indeksu Erozji Potencjalnej (EPI), do określenia którego wykorzystano obrazowania satelitarne LANDSAT w połączeniu z numerycznym modelem terenu oraz dostępnymi informacjami o glebach. W celu weryfikacji procedury wykorzystano zdjęcia lotnicze wysokiej rozdzielczości do określenia ilościowego lokalizacji wąwozów erozyjnych, a następnie porównano z wartościami EPI, wskazującymi przewidywane miejsca występowania wąwozów. Zdjęcia lotnicze wysokiej rozdzielczości wykorzystano również do oceny ilościowej wielkości erozji gleb spowodowanej erozją wąwozową w zlewni rzeki Potlatch.

    Opis:
    The paper deals with the spatial evolution of permanent gullies (under forest at present) in time in the northern part of the Nitra Hill Land (Slovakia) with the discussion on possible cause of their formation. For the purpose analyses of historical and current maps from the years 1783, 1838, 1882 and 2001 as well as aerial photographs from the second half of the 20th century and various historical written sources related to the years 1770, 1783, 1817, 1843 and 1956 were used. Based on the gained results an erosion activity of gullying can be found in the study area between the seventies of the 18th century to the sixties of the 20th century. Beyond the two main possible causes of the erosion activity as climatic change or (and) alteration in land use also conditions, such as agricultural system, different land use pattern, demographic characteristics or level of human society development may be considered.

    Opis:
    Erosion occurs in permanent gullies cutting into the undulating loess plateau in southern Poland. The gully slopes are mainly vegetated with beech trees as opposed to the surface of the plateau summit, which is cultivated agricultural land, devoid of forests for at least 18 centuries [od 18 wieków czy od XVIII wieku – czyli “since 1700s”?]. Beech roots are exposed in the gullies through erosion. Wood cells in the tree rings divide into early wood and late wood and, after the roots are exposed, also start to make fewer cells. In the roots on the border between exposed and unexposed tree rings in the tree roots, scars sometimes occur. This is an effect produced by corrasion by dolomites and limestones lying under the loess cover and re-deposition of building material stored by people in the higher part of the gullies. These anatomical changes in root tree rings allow one to date erosion episodes. Dating of the exposure of roots indicates that intensive erosion took place in the gullies starting in the 1980s. Since that time, numerous extreme rainfall events responsible for initiating erosion have also occurred. They contribute to deepening valleys causing new incisions to develop on hillslopes and headcut retreat in upper parts of the valleys studied at theWysoczyna Proboszczowicka near Góra św. Anny. The bottom of the valley head eroded during extreme rainfall events in 1984 and 1991. Erosion here alternates with deposition, its speed being relatively small. Incisions in hill slopes retreated during the flood in 1997, but they originated during earlier rainfall episodes. Such incisions retreat 2.5–3 m/year, i.e., relatively fast.

    loess gully erosion
    shear strength and natural moisture content in loess
    Opis:
    The article presents the problem of intense erosion in loess gullies in the locality Kazimierz Dolny. Primary reasons for such a quick development of gullies are: lithogenetic and physical-mechanical characteristics of loess, geomorphological and climatic conditions of the region and also human activity. Gully erosion impedes rural activity and communication in the area and causes considerable damages to local roads. In one of the loess gullies typical for the region, called ,,Opolska Droga” near Kwaskowa Góra, physical and mechanical parameters were examined by field and laboratory tests. The results revealed a clear correlation: shear strength of loess considerably decreases when its natural moisture content increases. What is also important, the structure of loess — loose soil skeleton mostly built of quartz and small amount of cementing clay particles — is prone to erosion. Thus, its adverse susceptibility to influence of water occurs to be primary reason of intensive gully erosion development in the area of Nałęczów Plateau . Additionally, geomorphological and climatic conditions, together with human rural activity (often using gullies as local ways of road transport) result in faster erosion development and, in effect, they lead to disastrous results like those that took place in the region during extreme rainfalls some years ago. Any stabilizing engineering works within loess gullies should be preceded by appropriately designed system for the regulation of run-off in the drainage area.

    Opis:
    Based on lots of surface movement and deformation observation data in loess gully region mine, the characters of surface movement and deformation caused by running activity are studied. Surface subsidence was up to 97% of the total subsidence in active period. Surface was moving with great crack and discontinuous deformation failure. The surface deformation developed rapidly, displacement angle is large, subsidence factor and horizontal movement factor is high. The results of surveying show that collapsible loess with the gully terrain lead to surface cracks which are quickly developed in loess. Crack failure are further intensified by mountain body slip induced by weight force. Meanwhile, subsidence factor and horizontal movement factor is gradually higher. Finally, the prediction model of horizontal strain and horizontal deformation were preliminarily established according to analysis results.
    W artykule przedstawiono charakterystykę ruchów i deformacji powierzchni terenów żlebów lessowych, spowodowanych działalnością górniczą. Osiadania powierzchni w okresie prowadzonej eksploatacji wynosiły około 97% osiadań całkowitych. Podczas ruchów powierzchni dochodziło do powstawania dużych szczelin i deformacji nieciągłych. Deformacje te zachodziły gwałtownie i charakteryzowały się dużym kątem zasięgu oraz wysokim współczynnikiem przemieszczeń poziomych. Wyniki przeprowadzonych pomiarów geodezyjnych pokazują, że zapadający się less w terenie żlebowym prowadzi do spękań powierzchni terenu, które szybko się powiększają. Spękania propagują jeszcze bardziej, gdy następują ruchy osuwiskowe skał i gruntów na skutek zaburzenia równowagi pomiędzy siłami ciężkości. W takim przypadku współczynniki przemieszczeń pionowych i poziomych rosną. Wyniki przeprowadzonej analizy pozwoliły na przedstawienie wstępnego modelu charakteryzującego poziome deformacje terenu.

    Brack Reservoir
    Opis:
    Strefa brzegowa Zbiornika Brackiego na rzece Angarze jest niezwykle ciekawym przykładem złożonego kompleksu procesów egzogenicznych z wyraźnym wpływem antropopresji, będącej wynikiem utworzenia zbiornika wodnego i jego eksploatacji. Badania monitoringowe, rozpoczęte jeszcze przed utworzeniem zbiornika, wskazują na transformację i intensyfikację przebiegu procesów egzogenicznych zachodzących na tym obszarze przed utworzeniem zbiornika (procesy osuwiskowe, procesy krasowe, erozja linijna), objęcie nimi kolejnych terenów, wcześniej pasywnych, jak również pojawienie się procesów nowych, przedtem nie występujących w tym regionie (procesy eoliczne, procesy abrazyjno-akumulacyjne). Badania te prowadzone są przez pracowników Instytutu Skorupy Ziemskiej RAN, a od kilku lat, w ramach dwustronnych umów, uczestniczą w nich również pracownicy Instytutu Geografii i Przestrzennego Zagospodarowania PAN.
    The Brack Reservoir on Angara river was created in 1967. It is the second in terms of capacity (170 km3) and surface (5,500 km2) man-made lake on Earth. Monitoring tests, that started before the reservoir has been created, gives the information about transformation and intensification of exogenous processes occurring in this area, in comparison to state before reservoir creation (landslides, karst, erosion processes). Those processes have taken new areas. Additionally on this area new processes have appeared as result of reservoir exploitation (eolian processes, accumulation-abrasive processes).
