Studie odtokových poměrů vybraného povodí pomocí hydrologického modelování
 Gottwaldová, Petra
The diploma thesis "Study of runoff conditions of selected river basin using hydrological modeling" deals with analysis of runoff conditions and retention abilities of the Kašnice stream basin in the Břeclav district. The theoretical part deals with the literature review of the issue and the characteristics of the selected drainage area. Obtained information about surface cover types, hydrologic soil groups and CN curves numbers were processed in ArcGIS. The outputs were then used as input for the DesQ-MAXQ hydrological model. The resulting values of specific flow, time of concentration, potential retention, water retention and direct runoff volumes are presented in the form of attached map outputs. The result of the work is the evaluation of runoff conditions of the given 4th order river basin.

Evaluation of soil infiltration rate by using compact pressure infiltrometer
 PIVOŇKA, Jiří
This thesis is focused on the evaluation of the infiltration capacity of soil in Lužický stream catchment in the cadastral unit Babice u Netolic. For the field measurement was used compact pressure infiltrometer. In the selected area were performed 26 infiltration experiments in 5 locations. In this thesis was compared infiltration rate at locations with different BPEJ (estimated pedologic-ecological unit), respectively HSP (hydrologic soil groups). Furthermore was also evaluated infiltration capacity on soils with different land use. To evaluate infiltration were used empirical infiltration equations according to Philip. Then the measured values were processed in tabular and graphical way. The highest infiltration rate was measured on arable land (L5). The classification of soil was examined according to HSP. Furthermore were also described in detail the principles of infiltration measurement using compact pressure infiltrometer.
