Vyhodnocení ohroženosti zemědělských pozemků vodní erozí ve vybraných k.ú. Opavy a Ostravy

Abstract

The diploma thesis is focused on the water erosion on agricultural lands in the cadastral selected Děhylov, Dobroslavice, Krásné Pole and Velká Polom. The first part is focused on the research of the general water erosion, erosion control measures and conditions in the study aerea. The practical part deal with the analysis of the various erosion factors and calculate the average long-term soil loss equation using the USLE. The main finding is that water erosion is extremely endangered and 53 % of the average annual removals of soil in these plots exceeding 10 t•ha-1. Based on this calculation the erosion control measures were proposed. These measures are designed to reduce the intensity of water erosion on the desired accessible value. The work is complemented by photographs and a map documents created in ArcGIS.
