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.

Analýza časových řad průtoků ve vybrané oblasti
HOCH, Tomáš
This diploma thesis deals with the methods used for flow measurement and their subsequent evaluation. The literature research describes basic hydrological concepts related to watersheds and runoff. The next chapter describes the methods used to measure and determine the flow of water flow rates. In the last part of the literature research, methods for evaluating time series are presented which are used to determine characteristics trends and oother statistics related to watershed and flow. This is fallowed by a practical part in which the investigated watersheds are described. Data on flows and precipitation are processed for each basin which are evaluated in the next section using selected methods. The results of these analyzes are subsequently described, compared with other researches and the possible causes of the changes that occurred are explained.

Měření průtoků a metody hodnocení časových řad průtoků
HOCH, Tomáš
This bachelor thesis deals with the methods that are used to measure water flows. The literature research describes the methods that are commonly used and for each is written a measurement procedure, according to which we find the required water flow. In addition, some of the methods for evaluating hydrological time series are described, which are used to obtain important information about the water stream and its water regime. Following practical part describes the selected rivar basin and changes in the landscape that occurred there after 1989. For selected river basin are measured daily flows via selected methods evaluated and then monitored progress and changes in the discharge regime of the basin. These changes are graphically recorded and the reasons that caused them are described.
