Evaluating the effectiveness of complex protection measures in cadastral area Jerlochovice in Husí potok Watershed
Matoušek, Petr ; Sobotková, Veronika (referee) ; Dumbrovský, Miroslav (advisor)
A subject of this Thesis is the design of the complex system of measures of soil conservation in given catchment area, which will serve as a concept of complex land consolidation in cadaster Jerlochovice. Based on the analysis and the land survey, a feasible solution was designed using the hydrological and erosive tools of ArcGIS. For the identification of areas endangered by erosion and for the identification of runoff conditions, the Universal Soil Loss Equation of Wischmeier-Smith was used (in grid modification). Based on the calculated values, the suitable technical and agrotechnical measures of soil erosion control were designed. Each component was designed for the values of Qn from the model DesQ. Subsequently the efectivity of the designed measures was evaluated by the comparison of results of erosive and runoff conditions before and after the aplication of the soil and water conservation measures.

Influence of landscape structure on the runoff and erosion condition in Stará Ves u Bílovce
Lízalová, Zuzana ; Ing.Kateřina Vašínová,Ph.D (referee) ; Dumbrovský, Miroslav (advisor)
This thesis deals with the influence of the landscape structure on the erosion and runoff conditions. The aim of the thesis is to analyze the erosion and runoff conditions of the landscape in the area of Stará Ves by Bílovec for three different time periods and for the design condition. The thesis is divided into four parts, the first part is theoretical, dealing with erosion and runoff conditions in the form of research. The second part analyzes the current state of the area. The third part of the thesis defines and evaluates the erosion wash off and runoff condiditons for given variations. The last part deals with the development of the land use from 1957 to the present.

Design of system soil and water conservation measures in Lhotecký stream catchment area
Pospíšil, Jan ; Ručková Sala, Aleksandra (referee) ; Dumbrovský, Miroslav (advisor)
The subject of the Master´s thesis is to design comprehensive flood control measures in the catchment Lhotecký stream in the built up areas of Nová Lhota village, who for several years struggling with the problem of water entering into the urban area during heavy rainfall. On the basis of this Master´s thesis, was created study of resolving the issue of flooding in the village, to a lesser extent, soil erosion and not least improve the ecological stability of the landscape around. For the analysis of the current situation was used digital maps in the GIS and subsequent application of the calculated values to the model DesQ. Through the standard formulas for dimensioning was created for a comprehensive protection of the village. This proposal will in the future serve as a basis for comprehensive land consolidation.

The design study of biotechnical erosion and flood control measures in the catchment of Jičínka river
Škrabal, Tomáš ; Ing.Kateřina Vašinová, PhD., (referee) ; Dumbrovský, Miroslav (advisor)
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.
