Design of erosion and flood control measures in the study case area responding to climate change
Mrázek, Vojtěch ; Larišová,, Lucie (referee) ; Sobotková, Veronika (advisor)
The aim of the work is to design anti-erosion and flood protection in the area of interest KÚ Lukavec to the current state and responding to climate change. At the same time, it is necessary to assess the degree of erosion threat to the soil and analyze runoff conditions in critical areas. The introductory part summarizes information about the studied area and methods for calculation. The erosion analysis is processed in the design part and suitable anti-erosion and anti-flood measures will be proposed. DesQ-MaxQ software was used to calculate the runoff conditions, graphical outputs and analysis of erosion conditions were created in the ArcGIS environment.

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.

Analysis of factors affecting a direct runoff from the catchment area
NEUBAUEROVÁ, Andrea
This diploma thesis follows my bachelor thesis. The main purpose of the bachelor thesis was to clarify fundamental terms and to explain the sorting of particular parts of a direct flow that involves both the surface saturated flow and the hypodermic flow. This diploma thesis is focusing on the origin of direct flow in a river basin. Specifically, it deals with river sub-basin P6, P52, and P53, which are located in Kopaninský potok river basin. Furthermore, it deals with Jenín I. and II. river basins and the last analysed is Ostřice river basin (SO2). Factors influencing direct flow are researched on all river basins. It is impossible to say that the origin of direct flow is caused solely by a single factor; it is always the result of multiple factors. Among these factors belongs the atmospheric precipitation, type of soil, vegetation, climatic and anthrophogenic conditions, land use, and inclination of the area. The bachelor thesis explains the issues of multiple methods of flow separation, but this diploma thesis is primarily focused on two methods for calculation of ratio between the direct and the total flow. 1) Empirical method GROUND, which is used to separate hydrographs of medium daily river basin flow. 2) Method of digital filter by Lyne Hollick separate fast and slowcomponents from the overall concentrated flow and are based on the theory od signal analysis. Afterwards, the results of flow separation were compared to the factors influencing the origin of the direct flow. The daily total flow rates for every analysed river basin were used as the input data for calculating the flow separation.

Direct run-off - formation and separation methods
NEUBAUEROVÁ, Andrea
The bachelor´s thesis occupies with an issue of a direct flow. The main purpose is the explanation of the basic terms of the issue and the explanation of the sorting of particular parts of a direct flow, that involves a surface saturated flow and a hypodermic flow. Subsequently the thesis describes its participation in the hydrogeological cycle, which means the participation in the permanent circulation of a surface and underground water on Earth. The extreme precipitations are dangerous due to their force, total sum and intensity. The inception of hydrological occurrences like floods or dry seasons is possible owing to this. The fallen precipitations have a big influence on a surface flow and a transportation of soil particles. The thesis is focused on the inception and the genesis of a direct flow. Further it focuses on the factors that influence the flow. Among these factors belong climatic and anthrophogenic conditions, vegetation, type of soil and atmospheric precipitations. There are clarified selected methods of potential separation which are explained and described in detail. This part of the issue mentions CN curve method, GROUNG method, MPGM, analysis of dropped subdivisions and finally method of digital filter (Chapman). These methods divides the flow on an elemental flow and direct flow.
