Study of runoff and erosion conditions in the Ketkovice cadastral area
Buršík, Lukáš ; Uhrová,, Jana (referee) ; Sobotková, Veronika (advisor)
This Diploma Thesis is focused on the analysis of the Ketkovice cadastral area in terms of runoff and erosion conditions. The QGIS software was chosen for the analysis. For this reason, instructions for this software are prepared, focusing on runoff and erosion conditions, as an appendix to the Diploma Thesis. Other software programs used are USLE2D and DesQ-MaxQ. The first part deals with the analysis of the area of interest. The second part deals with the problem itself, at first the methods used to determine runoff and erosion conditions are introduced, then anti-erosion measures, at the end of this part the software programs used are briefly described. The last third part is devoted at first to the evaluation of runoff and erosion conditions before the design of the measure, then to the design of the measure itself, finally to the evaluation after the design of the measure. In case of erosion conditions, two variants of calculating long-term soil loss are considered before and after the proposed measures. In the first variant, a constant value of the factor R=40 MJ.ha.cm.h is considered in the Universal Soil Loss Equation and in the second variant this value is increased with respect to the climate change.
