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.

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.

Modeling the impact of the potential anti-erosion measures in the selected area
KOKEJL, Karel
This diploma thesis deals with the topic of water erosion. Specifically, it is a matter of mitigating this process by applying an suitable anti-erosion measure. One of the goals of this work is that a suitable system of anti-erosion measures with a focus on technical anti-erosion measures is proposed for the selected area. Other technical aspects of implementation into the existing digital elevation model and verification of its functionality using the USLE equation in GIS (in this case in the ArcMap program) and modeling of povrchového runoff. In the theoretical parts of the work, the reader is acquainted with the basics of water erosion, detection of water erosion and anti-erosion hazards. Then it is introduced the introduction of the area of interest and the methodological procedure of the work, which is focused mainly on the calculation of erosion and dimensioning of anti-erosion measures.

Study of landscape proposals in the Hlinsko near Přerov Cadastral Area
Špaček, Stanislav ; Holomek, Michal (referee) ; Paseka, Stanislav (advisor)
The aim of this bachelor thesis is to characterize the area of interest, the municipality Hlinsko, to define the decisive factors determining the flood hazard of the intravillage of the municipality, to determine the critical points and the corresponding critical profiles, to define the erosion assessment areas and to define the erosion hazard on them. Subsequently, propose erosion protection organisational, agrotechnical and technical measures and appropriate erosion protection seeding practices. In the introductory part of the work, the existing knowledge on the subject and the procedures for determining the surface runoff values and the erosion hazard rate were defined. Subsequently, an analysis of the study site was prepared and in the final part suitable water management and erosion control measures were proposed.

Design of erosion and flood control measures contributing to water retention increasing in the landscape
Krátký, Jindřich ; Uhrová,, Jana (referee) ; Sobotková, Veronika (advisor)
The introduction of this bachelor’s thesis is focused on analyzing the territory of interest – the cadastral area of the municipality of Vevčice in the South Moravian Region of Czechia. Using ArcMap, USLE2D and DesQ-MaxQ software, the erosion and runoff conditions are evaluated, including the determination of the so-called critical profiles, where the concentrated surface runoff and sediments are currently posing a threat to the built-up area. On the basis of the analyses carried out, erosion and flood control measures have been designed. The measures should ensure the reduction of the average soil loss on agricultural land to permissible values, minimization of peak flows and protection of the inhabitants of Vevčice and their properties. Concurrently, the measures should contribute to water retention in the landscape. Furthermore, locations where the construction of small waterbodies such as a small reservoir, pond or wetland could be considered in the future, positively impacting the retention capacity of the local landscape, have been identified in the area of concern.
