Soil erosion risk is one of the most severe environmental problems that can affect water availability, agricultural productivity and consequently countries’ sustainable development worldwide. The current study was performed in Oued El Hamma Catchment, South-Eastern Tunisia to estimate soil loss, applying Universal Loss Equation (USLE) integrated with Geographic Information System (GIS) Remote S...

Abstract. Landscape morphology reflects drivers such as tectonics and climate but is also modulated by underlying rock properties. While geomorphologists may attempt to quantify the influence of strength through direct comparisons landscape metrics, recent work has shown that contact migration resulting from presence mixed lithologies hinder an approach. Indeed, this counterintuitively suggests...

soil erosion by water is the main factor of land degradation, particularly in semi-arid regions where soil productivity is usually low and lowering soil quality can severely decrease crops yields. this study was done in an area of 900 km2 in the semi-arid agricultural region of hashtroud in northwestern iran to determine the relationship between soil productivity and soil erodibility. wheat gra...
