Protecting of built up areas threatened by torrential rains
Horáková, Věra ; Uhrová,, Jana (referee) ; Dumbrovský, Miroslav (advisor)
This thesis investigates the design of complex systems measures against water erosion in cadastral areas Bílov, Butovice and Velké Albrechtice. Based on the exploration and analysis of the territory, it was suggested a possible solution by erosion and hydrological GIS tools. To identify areas at risk of erosion and runoff conditions were used a digital elevation model, Wischmeier-Smith equation and model DesQ. After that the effectiveness was evaluated by comparing the results before and after measures.

Sustainable production capabilities of territory, depending on climatic drought.
Skůpová, Jana ; Uhrová,, Jana (referee) ; Dumbrovský, Miroslav (advisor)
In this work, I dealt with the repercussion of drought on agriculture and land in the cadastral Jinošov. For this area, I analyzed the erosion and ratio of outflow. I also conducted a proposal of adaptation measures against erosion and water retention in the area. In conclusion, I analyzed withholding data and assessed the retention before and after the proposal of adaptation measures. The result of my work is finding that rainfall is inadequate and largely come out of the growing season, that despite all the measures fail to create on the necessary retention for the correct functioning of the landscape. Therefore it is necessary to solve water supply from other areas where is sufficient supply of water.

Using the Erosion Potential Method in the Czech Republic
Hloušek, Jakub ; Larišová, Lucie (referee) ; Dumbrovský, Miroslav (advisor)
The aim of this thesis was the evaluation of the loss of soil for the area of interest, located in the north-western part of the Němčického basin, in the district of Blansko. The calculation was made using two methods, namely erosion potential method (EPM), commonly used in Serbia and the Wischmeier-Smith universal soil loss equation (USLE), used in Czech Republic. Finally, both of these methods were compared with each other. Both methods use a different method of calculation. USLE method utilizes the universal equation for calculating the long-term average soil loss per year (G), the EPM method utilizes equation for specific average annual soil loss (Wsp, Wy). The calculation was performed with both methods in program ArcGIS while the USLE method was also supplemented with calculation of the factor (LS) with USLE2D program. When comparing the soil loss each of evaluated areas, the EPM achieved higher values of soil loss in the most of them. In contrast to the USLE method, the EPM the total loss of the soil from the evaluated areas also accounted the soil loss from forest areas. In terms of accuracy of the achieved real world results, it was determined that the conditions in the Czech Republic are more suitable for the USLE method and not only due to more accurate data input, but also because with EPM there is no factor that would better reflect the topographic factor and conditions of surface runoff in the territory.
