Types of gullies and conditions of their development in silvicultural loess catchment (Szczebrzeszyn Roztocze region, SE Poland)

Dobek K., Demczuk P., Rodzik J., Hołub B.

Landform Analysis

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.

Development and morphology of gullies in the river Daugava Valley, South - Eastern Latvia

Landform Analysis

Vol. 17

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.
