Flood prevention by using biotechnical measures
Pospíšil, Jan ; Pavlík, František (referee) ; Dumbrovský, Miroslav (advisor)
This thesis investigates the design of complex systems-natural flood control measures in the area of the cadastral municipality Jeseník nad Odrou. Based on the analysis and exploration 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. Subsequently, the effectiveness was evaluated by comparing the results navžených measure erosion and runoff conditions before and after measures.

Study of possibilities protection against rural zone water
Skolková, Daniela ; Roubcová, Radka (referee) ; Milerski, Rudolf (advisor)
This thesis is divided into two parts. The first part of thesis deals with the problems of soil erosion, surface runoff and measures affecting runoff. The part also explains the concept of surface runoff, and what are the most common methods taken to avoid water erosion caused by surface runoff. The next part about measures is divided into two chapters. The first part of measures describes the most common measures to increase the infiltration of surface runoff. In the second part of these measures were been described the measures to support water retention. The second part of the thesis includes methods of flood protection municipality Sebranice.

The design of the multipurpose small water reservoir
Pitka, Roman ; Dobešová, Renata (referee) ; Doležal, Petr (advisor)
Master´s thesis aims to design multipurpose reservoirs in the river basin Žlebovský potok in cadastre Vysoké Popovice. The main purpose of the reservoir will be improving the drainage conditions in the basin of the river and revitalization. The reservoir will be designed according ČSN 75 2410 – Malé vodní nádrže. The master´s thesis consists of a text section, hydraulic calculations and graphic attachments.

Identification of suitable places for retaining water in the landscape in the landscape in watersheds of the fourth order in the Trkmanka watershed
Valný, Patrik ; Larišová, Lucie (referee) ; Sobotková, Veronika (advisor)
The bachelor thesis is focused on the identification of suitable places for water retention in the landscape. The evaluated area consists of three selected catchments of the 4th order in the Trkmanka River basin in the South Moravian Region. In the first part of the work the analysis of the area of interest was carried out. Using ArcGIS, USLE2D and DesQ – MaxQ software, erosion and runoff conditions were evaluated to determine the critical points and critical profiles threatening the intravilanias of the municipalities by surface runoff and sediments. Also, the locations of the final profiles that threaten, for example, local roads were identified, these were then subjected to a field survey and photodocumentation was taken. Subsequently, small reservoirs were designed at the assessed and morphologically suitable locations. Finally, from the evaluated erosion and runoff data, a ranking of vulnerability was established.

Analýza vlivu kvality digitálního modelu terénu na odtokové charakteristiky pomocí modelování v GIS
LORENCOVÁ, Iva
This diploma thesis focuses on the analysis of the influence of the quality of the digital terrain model on the runoff characteristics in the Bedrč, Oldřichovec and Rájov river basins. The objective of this thesis is to create different digital models. Based on them, the surface runoff volumes are calculated. The resulting runoff volumes are compared with each other. The difference of runoff lines in space depending on the created DMT is also compared. The theoretical part of the thesis contains a literature search which focuses on the description of runoff, geographic information systems, creation of digital models and CN curve theory. The practical part of the thesis is focused on the description of the creation of digital models, calculation of surface runoff volume and calculation of culminating flow. The methodology contains a detailed description of the data processing for the creation of the 1st generation digital surface model, the 4th and 5th generation digital elevation model and the digital terrain model from contours. In addition, the practical part describes the process of calculating surface runoff volume and culminating flow. Then the results are evaluated.

Water areas localization in landscape as adaptation measures to eliminate climatic extremes
Mokrejš, Filip ; Moravcová,, Aneta (referee) ; Sobotková, Veronika (advisor)
The subject of the diploma thesis is the analysis of the cadastral area of the municipality of Čejkovice concerning erosion and runoff conditions. ArcMap and USLE2D programs were used to evaluate erosion conditions. The determination of runoff characteristics was preceded by the identification of critical profiles, for which the calculation was subsequently performed in the DesQ-MaxQ program. Based on the evaluation, suitable erosion control measures were proposed, and the post-design condition was evaluated. Finally, the work focuses on small water bodies. Using the available literature, recommendation criteria for the selection of locations for small water bodies were established and a selection of suitable sites in the area of interest was made. The selected sites were developed into details of documentation for planning permission.

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.

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.
