Analýza erozní ohroženosti v zájmovém území

This diploma thesis deals with the analysis of the threat of water erosion in the cadastral areas of the municipalities of Horní Poříčí, Prostřední Poříčí and Dolní Poříčí, which is located in the South Moravian Region in the district of Blansko. The thesis also contains draft anti-erosion measures, based on the analyses performed. The first part of the thesis consists of literary research focusing on erosion issues focusing on the legislative framework of soil protection. This part also contains the characteristics of the area of interest. The next part is focused on the determination and explanation of the processing procedure used in the practical part. Here is explained the principle of calculating the average long-term loss of soil by water erosion by the universal equation USLE according to Wischmeier and Smith and the determination of the individual factors entering this equation. The methodology also describes the process of calculating individual factors and the long-term loss of soil by water erosion in ArcGIS, USLE2D and LS Converter. Data BPEJ, LPIS and ZABAGED(R) were used for processing. The practical part contains proposal of anti-erosion measures and analysis of erosion hazard after their application in the area of interest. The results are presented in the form of manual outputs, always for the current state and for the status after the application of the proposed measures
