Gully erosion identification and analysis in Belgorod region

Abstract

A map of gullies distribution has been compiled for Belgorod region on the basis of studies undertaken, 5 types of areas being established different in gullies density. Quantitative parameter has been obtained which reveals natural and anthropogenous factors impact on gully dissection of and area. 5 factors have been established which determine spatial differentiation of gullies density, relative importance of each factor being defined for each type of areas. The main reason of the areas types separation appeared to be variation in forested area percentage, mean slope and spring discharge. Taking into account the regional natural features the factors combination has been identified which presents most serious gully erosion hazard.
