Water management solution of Tršice reservoir
Chyba, Martin ; Fína, David (referee) ; Starý, Miloš (advisor)
The master thesis follows the bachelor's thesis entitled Water management solution of a small water Tršice reservoir. The object of the work is the completion of the water management solution at the Tršice reservoir. In the terms of the storage function of the reservoir, it will be a question of finding a possible increase of runoff for irrigation in the growing season of various crops. In the terms of the protective function, it will be a transformation of flood waves of Tršice reservoirs and below ponds.

Water management solution of Těšetice small water reservoir
Žiaček, Tomáš ; Fína, David (referee) ; Starý, Miloš (advisor)
This Bachelor thesis describes the locality of “Bohuňov pond” and “Těšetice dam” cascade. Next the efficiency of storage and protective functional space is assessed as well as the possible draft of reallocation of the sizes of the “Těšetice dam” volumes considered is added. In the analysis of “Bohuňov pond” and “Těšetice dam” cascade protective function the dimensions of storage space are tabularly processed, i.e. dimensional solid safety deposit of Těšetice dam for safe flood wave conversion. The calculations are made on current data.

Control of storage function of the reservoir
Hon, Matěj ; Matoušek, Petr (referee) ; Kozel, Tomáš (advisor)
Dispatcher graphs state the amount of discharged water according to the current status of a water tank. The thesis describes the technique of creating a zonal dispatcher graph and its simulation on a large open water reservoir Vranov. Using predictions, the model was tested to know how it works with the ability to determine incoming tributaries. The dispatcher graph method is commonly rated among deterministic control methods. These methods are advantageous in one specific output and that is a control variable. Other possible ways are stochastic methods that work with probability and give us the control over the choice of a procedure. Both types of methods are further described in the work. For the suitable prediction of flows, the use of a neural network operating on the principle of reverse propagation was chosen.

Control of the reservoir storage function using artificial intelligence methods
Hon, Matěj ; BBA, Šárka Zemanová, (referee) ; Kozel, Tomáš (advisor)
The diploma thesis deals with flow prediction using artificial intelligence to control the storage function of the reservoir. It focuses on the control of storage function using combination of dispatching graphs and flow prediction. The work is divided into a methodological part and an application part. The methodological part contain describes how the acquisition of historical data, a description of the work of dispatching graphs and forecasting models. The application part contains flow forecasts and outflow control. A prediction model is based on the fuzzy method, and it is used to predict inflows. The calibration and validation of the prediction model is also described. Results of prediction model were evaluated. In next step the results of control method were evaluated and compared with result of dispatching graphs. The results of controlled method were satisfactory.

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.

Water Management Analysis of Storage Capacity of the Vranov Reservoir
Vítková, Lucie ; Havlík, Martin (referee) ; Marton, Daniel (advisor)
The current persistent drought and changes in the climate system have raised water managers expert questions about how to manage water resources in the future. The manifestation of climate change in hydrological series and their influence on the magnitude of threats to the storage functions of reservoirs are more often investigated. Already today, long-term shortages of storage capacity in reservoirs lead to the introduction of special manipulations on water structures. The aim of the thesis is to perform the analysis of time series, respectively decomposition of hydrological series average annual and monthly discharges. Create extended hydrological bases using synthetic discharge series generators and develop a comprehensive analysis of storage volume without considering losses even with the introduction of losses from the water surface vapor in the UNCE RESERVOIR program. The created discharge series are compared and evaluated on the basis of statistical characteristics and reservoir storages results with the real discharge series. The practical app is conducted on the Vranov reservoir in the Dyje River Basin.

Theme of the work is a water management analysis of the Hanušovice reservoir on the river Morava/Krupá. In the framework will be make to calculating of the thinking reservoir, which in Generel locals for accumulation surface waters LAPV is conduction as perspective water-supply reservoir for north and central Pomoraví. Software will be used, which calculating analysis reservoir enable carry out. Target of the work is analysis variable reservoir, which is conduction on actually hydrologic conditions in river basin a actual lay requisition national company Povodí Moravy.

Assessment of the Vranov Reservoir Storage Capacity in the Context of the Reservoir Bed Morphology Evolution and Hydrology Characteristic of the River Basin
Jílek, David ; Pavel,, Menšík (referee) ; Marton, Daniel (advisor)
The main function of the reservoir storage volumes is an accumulation of fresh water. Due to the reservoir sedimentation, the impact of climate change, and also unsuitable agricultural land management, a gradual capacity loss in the reservoir storage volumes is happening. The aim of the paper is to provide a storage capacity analysis of the Vranov reservoir. The analysis was made using the historical and updated input data, specifically morphological and hydrological data. The historical-morphological data were taken from the handling regulation guidelines. The upgraded morphological data were in the form of actual reservoir bathymetry measurement from 2021, from which the values of the volume and of the area for reservoir area-volume curves drawing were calculated. Bathymetric measurement was a part of an international project INTERREG AT-CZ "ATCZ28 SEDECO - Sediments, ecosystem services and interrelation with floods and droughts in the AT-CZ border region" as a cooperation between Povodí Moravy, s.p. and BUT FCE. The hydrologic data were provided by Czech Hydrometeorological Institute and have been updated till 2020. It includes an extreme drought event between 2015 and 2018 that significantly affected the results of the analysis. Based on the input data as well as reservoir storage simulation, an analysis of the reservoir storage capacity considering the water evaporation loss was created. The analysis has been made both for the deterministic and statistic solutions. In the statistic solution, a calculation of storage volume involving input data uncertainty was done. The partial results of the analysis were published in the paper Marton and Jílek: Posouzení zásobního objemu nádrže Vranov na aktualizovaná vstupní data. This paper was also a part of the presentation at the international conference Vodní nádrže 2022 in Brno organised by Povodí Moravy, s. p.
