Výpočet odtokových poměrů v GIS v závislosti na kvalitě DMT vzniklých z různých vstupních dat
PLIC, Vítězslav
This thesis deals with the calculation of runoff parameters in the Třísov stream catchment using geographic information systems (GIS). Various digital terrain odels were created and compared from different input data, including the digitization of existing maps and the surveying of the terrain using GNSS and tachymetry methods. Subsequently, runoff ratios were calculated for design rainfall events along with other input data. The thesis examines the impact of input data quality on the accuracy of runoff ratio determination in a small catchment. The analysis includes the examination of runoff paths, the comparison of runoff before and after adding an unknown watercourse to the digital terrain model, and the determination of the amount of water retained in the watercourse. The aim of this thesis was to improve the quality of input data for more precise and reliable determination of runoff parameters in the landscape.
