Modelování vodní eroze s využitím GIS a dynamických erozních modelů

Abstract

The main topic of my diploma thesis is studying and modeling of erosion and sediment removal by using GIS and hydrodynamic models in the watershed of the river Becva. The first part describes the natural condition of the pilot areas, outlines the problems of erosion, characterizes its species, analyzes its causes and consequences. Other chapters are devoted to geographic information systems, used simulation models of surface runoff and erosion and the input data. The practical part describes the methodology of work and modeling scenarios in the dynamic erosion model SWAT, SIMWE and using a static equation RUSLE. The final section presents the obtained results in the form of graphics and map layouts, their evaluation and comparison of different methods.
