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.

Zárubová, Kamila ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This bachelor’s thesis deals with the flood control measures in the basin Březnice. This mainly concerns the assessment of flow rates. The work is divided into two parts: A description basin and data processing in programs ArcGIS and Hydrog. Description of the basin is the description of geographic factors, personal acquaintance with the river, and residents of surrounding villages bordering the stream. Subsequently the river will be process and scheme in program ArcGIS - the catchment area will be divided into partial hanging areas with which it will be worked next. The outputs obtained in this step are used for data processing in the Hydrog program. The intensity of rainfall and the N-year flows will be also calculated . In the end flow rates obtained from the program Hydrog will be compared with the real flow.

Search and Comparison of Methods for Calculation of Reservoir Storage Yield Analysis
Michálková, Veronika ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The ever-increasing threat of climate change is bringing the issue of water resources, both groundwater and surface water, to the fore. Hydrological extremes in the form of floods and droughts have always been there. However, their intensity has increased and they have a much greater scale and impact on life. On the one hand there is a need to retain and store water for further economic use, on the other to transform flood waves and try to prevent the devastating effects of floods. In view of these facts, the aim of this paper is to develop a comprehensive overview of methods for calculating the size of reservoir storage volume, which is one of many tools for effective mitigation in the perspective of combating drought. The text includes methods from both foreign and Czech perspectives. Five methods were applied on the inflow of the Vír reservoir presented by a flow series. Two of the selected ones are sequent peak algorithm which uses sequential balance of inflow and outflow from the reservoir. They are used abroad. The other method is a direct solution to the size of the reservoir storage volume size, which was taken from the study materials at CTU Prague. Also from this area is the progressive balance method and finally the problem of type A.1 is calculated, which appears in the study materials of the Faculty of Civil Engineering of Brno University of Technology. The practical application of the methods also provided a comparison of the results of the calculations and their differences.
