ANALYSIS OF EROSION VULNERABILITY OF AGRICULTURAL LAND IN THE CATCHMENT OF LUH STREAM USING THE GIS TOOLS

Utilization of geographic information systems (GIS) for the erosion vulnerability analysis of agricultural land is shown on the example of Luh stream catchment, Czech Republic, district of Vysočina. Evaluation of soil erosion conditions according to the Universal soil loss equation (USLE) was done in ArcGIS 10 Desktop, software product of ArcInfo using a set of integrated software applications ArcMap, ArcCatalog and ArcToolbox user interface with LS-converter and USLE2D programs. The project of erosion control measures and evaluation of their effect on the erosion were parts of the analyses. Erosion control crop rotations with soil protective technologies, that change the value of cover-management factor, were used as erosion control measures. ...
