Analysis of hydrograph timing parameters for selected watersheds

The purpose of the graduation thesis is to present the theoretical basics of runoff hydrograph, timing \nparametres and their estimations and also the affecting watershed characteristics. The practical part is \ncomposed of defining timing parametres from gauged hydrographs of selected basins and comparing \nto the results of empirical equations. \nIn the first part the graduation thesis presents the runoff basics, as part of the hydrologic circle, are \npresented. There is also the description of the hydrograph, its components and characteristics. The use \nand characteristics of the unit hydrograph are given. Furthermore, there is a chapter about the \ngeographical and meteorological characterisctics of the watershed and their affect on the shape, \nduration and maximum runoff volume of the hydrograph. Timing parametres and their definictions are \ndescribed. In case of parametres with multiple definictions, all of them are descibed and their \ndifferences are submited. The following part contains the methods and equations for calculating the \nvalues of these parametres. The methods are divided into three approaches: the analysis of gauged \nhydrographs, the velocity method and the empirical equations. Numerous equations are listed with \ndetails. The process of defining timing parametres from gauged hydrographs and rainfall is presented. \nFor the selected basins multiple hydrographs were defined from measured data. Timing parametres \nwere then gathered from the hydrographs. The watershed characteristics for empirical equation \ncalculation were obtained by geographic information systems. The results were examined and \ncompared.
