Water management analysis of reservoir under climate change
Smolík, Lukáš ; Benáčková, Kateřina (referee) ; Marton, Daniel (advisor)
The presented bachelor thesis is focused on the analysis of impacts of climate change on the water reservoir. The work consists of several partial steps. The first step is the calibration of the balance of the hydrological model to the current climatic and hydrological conditions. The next step is the construction of hydrological time series burdened by climate change. That the calibrated model was compiled, it must be used calibrated balance model and climatic data loaded climate change. Selected emission scenario used in the work of the emission scenario RCP4.5 the final step of the work is to analyze the reservoir volume by using the simulation model of the tank and its evaluation in view of possible future climate change. The functionality of the described procedures will be verified for the analysis of impacts of climate change on the reservoir capacity of the reservoir in the defended Hanušovice profile in the Morava river basin.

Hydrological Time Series Analysis for Chosen Sub Catchment in Morava River Basin
Černý, Vojtěch ; Benáčková, Kateřina (referee) ; Marton, Daniel (advisor)
Current climate conditions raise questions about how climate change should affect the hydrological regime of the Czech Republic. The main questions are: I) Is climate change serious and is it already tangible in hydrological series? II) Are there significant changes in the climatic conditions, or in the flow of the river network? III) How does climate change affect hydrological conditions in the catchment? IV) Are there non-stationary tendencies in the hydrological series caused by climate change? The aim of this work was to perform a basic analysis of hydrological time series and estimated its possible changes. The analysis was done with using autocorrelation function, spectral density, moving averages methods, statistical characteristics, empirical line of probability of exceeding and last but not least by decomposing the time series. The practical application was applied on time series of average monthly flows determined in the hydrometric profile of Dalečín in the Svratka river basin.

Rainfall runoff process in time of climate change
Benáčková, Kateřina ; Janál,, Petr (referee) ; Marton, Daniel (advisor)
The aim of The Diploma Thesis was to compile a conceptual rainfall-runoff model, that would be eligible to model discharge in conditions of climate changes. After thorough verifications of possible variants, user program Runoff Prophet that is eligible to simulate discharge in closing profile of any river basin was compiled within this paper. Runoff Prophet is deterministic lumped model with monthly computation time step and from the hydrologic phenomena it takes soil moisture, evapotranspiration, groundwater flow and the watercourse flow into account. Its calibration is based on the differential evolution principle with Nash–Sutcliffe model efficiency coefficient as the calibration criterion. Developed software was tested on Vír I. catchment basin and the results of this probe were evaluated from viewpoints of air temperature, precipitation and discharge characteristics in the Dalečín measurement river cross section in distant future according to A1B SRES climate scenario, implemented in LARS-WG weather generator.

Generating of Stochastic Rainfall Data Using by Specific Weather Generator
Benáčková, Kateřina ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The aim of this work is to study the topics of climate change, SRES emission scenarios, global GCM and regional RCM climate models, which are necessary basis for using the LARS WG software (Stochastic Weather Generator for Use in Climate Impact Studies). Based on given knowledge using LARS WG the testing time series of daily precipitation and temperatures data will be generated for three future time periods. The observed weather data from the Meteostation VUT was used. Generated data will be analysed and interpreted for its future uses.

Summary of a potential evapotranspiration calculation methods in the selected river basins
Bedáňová, Jana ; Benáčková, Kateřina (referee) ; Marton, Daniel (advisor)
The master's thesis deals with the research of available methods for calculating potential evapotranspiration and the subsequent application of selected methods. The text part describes general knowledge about evapotranspiration, specific types of vapors from different surfaces (water, soil, vegetation, snow cover, urbanized area). The following are methods of direct measurement, where the types of vapor meters are described, for which types of vapors they are used. Indirect measurement methods for determining potential evapotranspiration and their distribution are also described here. The main part of the research is empirical methods for calculating potential evapotranspiration, here is a selected list of these methods. Furthermore, a practical application of the method according to Thornthwaite, Hargreaves-Samani and Hargreaves-Allen is carried out using data from the Olomouc-Holice precipitation station, the data of which are available from the ČHMÚ portal. Then a comparison of the used calculation methods is made.
