Evaluation of a Water Reservoir Bed Morphology Using Bathymetric Data
Jílek, David ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
Sedimentation of reservoirs is one of the current problems in the field of water resource management. The actual conditions of the bed morphology can be scan by modern bathymetric sensors or measuring and then transferred to digital terrain models. This bachelor thesis evaluates the process of the sedimentation of the upper reservoir of Nové Mlýny reservoir since its first filling in 1978 to the newest measuring in 2018 using an assessment of a water volume changes in the reservoir. The thesis also describes a detailed manual of reservoir volumes evaluation in the programs ArcGIS and Atlas DMT, and verification of the method accuracy. These programs were used for creating the digital terrain models and calculating area-volume curves that were utilized for evaluation of a volume change and then for the amount of the reservoir sedimentation. The total volume of the reservoir loss during the forty years is estimated as 500 thousand m3 which equals 28 % of the total reservoir volume, at least the 300 thousand m3 of sedimentation was realised in the last ten years. The outcomes are part results of the project ATCZ28 SEDECO – Sediments, ecosystem services and interrelation with the floods and droughts in the AT-CZ border region.

Water Management Analysis of Reservoir Storage Capacity Due to Climate Change
Šenková, Monika ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The aim of this work is a water management solution of the storage volume of the Vlachovice reservoir in the conditions of climate change. Due to the long-term drought and flood period, the Czech Republic decided to build multi-purpose reservoirs. One of them is the multi-purpose water reservoir Vlachovice. The tanks are designed for a certain storage volume, which is calculated from the flow series in a given water profile. Flows on watercourses are conditioned by climatic and geomorphological conditions. Climatic conditions are constantly changing and significantly affect flows. It is difficult to determine the future of water flows. Future flows are generated based on measured values ??and expected climate change using mathematical models. In this work, just these two scenarios of the future of flow series depending on the amount of precipitation and temperature changes are compared.

Creating a Hydrological Model to Determine Maximum Runoff from a Small Catchments
Hakl, Petr ; Pospíšilík, Šimon (referee) ; Menšík, Pavel (advisor)
The aim of the thesis is to set a hydrology model based on existed methodology DesQ-MaxQ, which comes from "Designing flows from a very small catchments" established in 1989. The model is able to set a nearest meteorology station and his 24-hours rainfall depths for periods of repetition 2,5,10,20,50 and 100 years. Substitute rainfall depths are set by "reduction of 24-hours rainfall depths" methodology. According to hydraulic and hydrology conditions of catchment, duration of the critical rains for each period of repetition are set also peak flow rates and total runoffs from the catchment. Application can work in two modes - "one slope" and "two slopes". The second option also includes calculation of design duration for the model catchment and superposition of hydrograph. Application RainRunoff was develop in C# programming language with graphic user interface and option to exports hydrographs.

Relation Between River Flows and Suspended Sediments in the Selected Hydrometric Profile of the Thaya River Basin
Bobková, Dominika ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The issue of the sediments of their transport and subsequent storage in water basins is an important topic which is perceived very seriously by the water management expert public. Therefore, work in this area is very desirable. The aim of bachelor‘s work is to find and estimate possible dependencies between average daily discharge and average daily values of non dissolved substances carried in suspension. The dependencies will serve as a partial basis for addressing the ATCZ28 SEDECO Sediments project, ecosystem services and interrelation with floods and droughts in the AT-CZ Border region. The data are analysed in different periods of time. The result of the analysis is the trend line regulations and the degree of dependence between flows and concentrations, which is expressed by means of a coefficient of determination. The practical application is performed on data measured in the Trávní Dvůr profile on the Dyje river for the years 1996 and 1997.
