Evaluation of erosion control measures described in GAEC II by using hydrological modeling

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)
