The design study of biotechnical erosion and flood control measures in the catchment of Jičínka river

The main subject of this diploma thesis is a study of a suggestion of environmentally friendly adjustments in the basin of Jičínka, working as preventive protection against floods. The study contains a research of the stated area using the method of CN-curves in the hydrological model DesQ-MaxQ and the principle of Wischmeier-Smith's equation, in modicication of ArcGIS programme. Based on the analysis, the work suggests an improvement of erosive and drain ratios and then an assessment of effectiveness of the protection. We get the assessment of the effectiveness by comparing the condition of the erosive wash and the surface drain before and after implementation of our measures. The work also sets its goal in calculating the financial returnability of the investition indicatively
