Mathematical modeling of the erosion processes in hydrographic basins

Abstract

The erosion is a complex process determined by many physical, chemical, biological factors, affects the environment in a number of ways, and has a significant impact on the conservation and exploitation of natural resources, as well as on the quality of life. Due to its complexity, it is crucial to build a good erosion model in accordance with the envisaged main effects. The most determinant factors in the soil erosion - the process we focus in this article - are water dynamics, soil particle cohesion, and the cover plant presence. Our study focuses on the topography influence on water dynamics, the interactions plant cover - water flow, soil particle detachment - plant cover. We also analyze the model sensitivity to the variation of some soil parameters.
