Soil erosion is a direct product of the complex interactions between natural and
anthropogenic factors. Such factors vary over space and time, making the assessment of soil …

This study focuses on the role of topography in soil erosion modelling by examining the
impact of topographic data from various sources on the calculation of the slope length and …

A Digital Elevation Model (DEM) refers to a quantitative model of a part of the earth's surface
in digital form (Burrough and McDonnell, 1998). A DEM consists of either (1) a …

Evaluation of open Digital Elevation Models: estimation of topographic indices relevant to
erosion risk in the Wadi M’Goun wat Page 1 AIMS Geosciences, 6(2): 231–257. DOI …

Soil erosion is a key concern for the environment and natural resources since it leads to a
decline in-field productivity and soil quality, resulting in land degradation. In this study …

Many hydrological algorithms have been developed to automatically extract drainage
networks from DEM, and the D8 algorithm is widely used worldwide to delineate drainage …

Quantitative estimation for soil erosion is necessary for protection of the environment, and to
improve agricultural productivity. However, due to the large area, sparse and limited data in …
