Abstract

The main intention of the thesis is analysis of rainfall-runoff methods' capabilities for land cover impact analysis applied to the Odra to Opava catchment. The first (theoretical) part of the thesis deals with hydrological cycle, rainfall-runoff process and the description of factors affecting rainfall-runoff process. It also contains the description of the process of rainfall-runoff modeling, the localization and the characterization of the natural conditions of the interest catchment. The source data and the characterization of used hydrological models HEC-HMS, HYDROG and MIKE SHE are also described in the first part of the thesis. The second (practical) part of the thesis is focused on describing of the way to select episodes of rainfall-runoff and the description of selected rainfall-runoff episodes themselves. The basin schematization, the setting models and the simulations of selected rainfall-runoff episodes, at first in the current state of land cover of catchment and then for scenario representing completely forested catchment are made further. The simulations were executed in HEC-HMS, HYDROG and MIKE SHE. The simulation results were continuously analyzed and commented appropriately. The effect of forest vegetation cover on rainfall-runoff processes is evaluated and also the analysis of rainfall-runoff methods' capabilities for land cover impact analysis is made in the final part of the thesis. The connection of hydrological models and geographical information systems was used in the thesis.
