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.

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.

Opis:
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.

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.

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.
