Simulace vlivu potenciálně vybudované vodní nádrže na odtok vody z vybraného povodí
 HOŘEJŠÍ, Štěpán
This thesis consists of a literature review and a practical part focused on water retention - one of the crucial functions of water reservoirs. The aim of the thesis is to use the hydrological model HEC-HMS to simulate the impact of the water reservoir on the water runoff from the catchment area in the selected watershed and demonstrate how water reservoirs are able to affect the hydrograph during rainfall runoff events. In the included literature review, water reservoirs and their classifications are defined. Subsequently, precipitation and runoff, as well as the rainfall-runoff events, are explained. At the end of the literature review, various hydrological models are presented, with a closer description of the HEC-HMS hydrological model. The practical part consists of a description of the catchment area and the constructed water reservoir. This is followed by an analysis of the used method, including the necessary calculations for hydrological modelling. Finally, obtained results are presented and evaluated.

Analýza vlivu potenciálně vybudovaného vodního díla na odtok vody z vybraného povodí pomocí hydrologického modelování
 REZEK, Alfred
The object of this dissertation is to describe the influence of water works on the outflow from a watershed through the Hydrologic Modelling System Hec HMS. It is a direct application to the particular watershed of the Bílský Stream. In the theoretical part about relevant literature, solutions to the topics related to this issue are found. It focuses especially on the water balance in the watershed; the outflow from the watershed and other factors by which the watershed is influenced; extreme flows and flood activity with appropriate security steps such as water basins. At the end of the part on the literature, there are five different systems for creating hydrologic models with the specialisation on the Hec HMS model. The practical part is about preparing input data for the hydrologic model and its subsequent creation. Particular runoff from different N-year precipitation (N = 2, 10, 50 and 100) are compared. Two hydrologic models have been created for comparison, one with the watershed without a reservoir and the second one with a reservoir included. The resultant part is about watching flows, volumes of runoffs and the tranformation of the flood wave in a reservoir between N-year precipitation and two different models of watershed.
