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.

Influence of landscape structure on the runoff and erosion condition in Stará Ves u Bílovce
Lízalová, Zuzana ; Ing.Kateřina Vašínová,Ph.D (referee) ; Dumbrovský, Miroslav (advisor)
This thesis deals with the influence of the landscape structure on the erosion and runoff conditions. The aim of the thesis is to analyze the erosion and runoff conditions of the landscape in the area of Stará Ves by Bílovec for three different time periods and for the design condition. The thesis is divided into four parts, the first part is theoretical, dealing with erosion and runoff conditions in the form of research. The second part analyzes the current state of the area. The third part of the thesis defines and evaluates the erosion wash off and runoff condiditons for given variations. The last part deals with the development of the land use from 1957 to the present.
