Evaluation of erosion and runoff conditions in the Fryšávka basin
Špaček, Ondřej ; Kulihová, Martina (referee) ; Sobotková, Veronika (advisor)
Bachelor thesis is focused on the evaluation of the erosion and runoff conditions in the basin of the Fryšávka river. The objective of the thesis is the analysis of the soil loss, identification of critical points and profiles, determination of their characteristics and overall assessment of the vulnerability of cadastral territories. Analyses were carried out according to the applicable methodologies, with the use of programs ArcGIS, USLE2D and DesQ-MaxQ. In the assessed territory has been identified 6 critical points and 31 critical profiles. In twenty of them was carried out the calculation of flow rates. The calculated data was complemented by field research and photo documentation. From the evaluated data of the erosion and runoff conditions was made a ranking of the vulnerability. At the conclusion of the thesis are recommended the most vulnerable cadastral territories for further analyses and design of soil and water conservation measures which would mitigate the negative consequences of the identified unfavourable conditions.

Design of erosion and flood control measures for the selected cadastral area
Svoboda, Jiří ; Uhrová,, Jana (referee) ; Sobotková, Veronika (advisor)
This bachelor thesis is in the introduction focused on the evalutation of the current erosion and runoff conditions in the cadastral area of Zádolí u Vysokého Mýta and in the cadastral area Střihanov. The analysis of current erosion and runoff conditions is carried with the use of programs ArcGIS, USLE2D and DesQ–MaxQ. The following is a design of erosion and flood control measures with the main aim of protecting the village Zádolí–Střihanov. Then the design technical measures are dimensioned for the specified design flows. In conclusion of the thesis is evaluated the efficiency of the design protective measures and the average soil loss and runoff quantities are compared before and after the design of the protective measures.

Protection of the built-up area of the municipality by the proposal of water management measures in the river basin
Majkus, Martin ; PhD, Ing František Pavlík, (referee) ; Dumbrovský, Miroslav (advisor)
The aim of this paper is to evaluate the important factors that determine the flood risk of the built-up area in the surveyed location. Also, it is necessary to assess the intensity of erosion treat to the soil and then propose comprehensive protective measures in the catchment areas of critical points and profiles, which will reduce these unfavourable values. The introductory part will summarize the existing knowledge and methods for determining the values of surface runoff and the degree of erosion risk. In the design part, surveyed locality analysis will be proved. Furthermore, the suitable water management measures will be proposed. The measures will ensure the protection of built-up area of the municipality and improvement of erosion conditions. For analysis of the area and for propose of measures were used ArcGIS-ArcMap and DesQ-MaxQ software. Obtained information was then processed in MS Excel and Word editors.

Design of erosion and flood control measures for study of runoff and erosion conditions
Svoboda, Jiří ; Larišová,, Lucie (referee) ; Sobotková, Veronika (advisor)
This master’s thesis is in introduction focused on the detailed characteristics and analysis in the cadastral area of Sivice. Erosion conditions are determined with using programs ArcGIS and USLE2D. Runoff conditions are evaluated by the method CN curve with using programs the ArcGIS and DesQ–MaxQ. After the analysis follows a design of erosion and flood control measures, the purpose of which is protection of the intravillan village of Sivice from torrential floods and protection agricultural land from water erosion. After the drawing design, biotechnical and technical measures are dimensioned for the design flow rates specified in the model DesQ–MaxQ. A detailed description belongs to all the protective measures. In conclusion of the thesis is evaluated the efficiency of the design protective measures and the average soil loss and runoff quantities are compared before and after the design of the protective measures.
