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.

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:
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.

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.

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:
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 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.

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.

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:
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.

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:
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 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.
