Verification of the dependence between rain intensity and N-year flow for selected river basins with measurement
Tomášek, Lukáš ; Zemanová, Šárka (referee) ; Kozel, Tomáš (advisor)
The diploma thesis deals with the verification of various precipitation events in the selected river basins with measurements. As part of the work, schematization is for a given river basin made and a precipitation-runoff model is created and calibrated based on measurements in the final profile for 2 variants of calculations. Alternative rain intensities with different periodicity and duration are then tested on the calibrated precipitation-runoff model to achieve the required flow rate Q20. Finally, the aforementioned results are evaluated and recommendations are made from them.

Evaluation of erosion control measures described in GAEC II by using hydrological modeling
HRDINA, Filip
Erosion is an issue, which causes huge damages not only on agricultural land. This diploma thesis describes practical evaluation of erosion control measures (usage of leaving crop residue, circuit strips, contour tillage), which are include in Good Agriculture and Environmental Condition standart, which was issued by European union. Efficiency of usage of narrow-row and wide-row crops is also modeled. Each measures were evaluated in two different modeling programmes HydroCad for calibration and ERCN for results comparison. Seven different scripts are used in the thesis. Subcatchment area P6 in catchment area of Kopaninský creek is used as model area. Literature review describes the precipitation and runoff process, issue of erosion, and agriculture land protection against water erosion. Is also describes GAEC standards (today DZES).
