Work presents physical geography of the Úpa River basin from the point of view of geology, geomorphology and soil characteristics. Climate, hydrography and hydrology are described in more detail. Úpa River basin is specific in its shape and position in the headwater where runoff is generated. Four sub-basins (Horní Maršov, Horní Staré Město, Slatina nad Úpou and Zlíč) were used for evaluation of mean areal precipitation (MAP) computation method impact on simulated flows. MAPs were computed for four intense rainfall episodes using arithmetic, Thiessen polygon and different settings of inverse distance method (= 2 or 3). These MAPs enter into hydrological forecasting and modeling system AquaLog that includes rainfall runoff model SAC-SMA. AquaLog and SAC-SMA are also described in this thesis. Modeled runoff series (based on different initial conditions) were analyzed in the meaning total runoff, peak flow, and fast runoff components (surface, sub-surface and direct). Results show that optimal results in the higher part of the basin provide inverse distance method with  set to 3. Powered by TCPDF (www.tcpdf.org)
