Determination of floodplains and hydrotechnical assessment of Mastník water flow based on the DMR 5G data
 Čápová, Pavlína ; Roub, Radek (advisor) ; Havlíček, Vojtěch (referee)
This work engages in the watercourse called Mastník. It focuses on the determination of flooded areas for couple of series (Q5, Q10, Q50, Q100) and hydro-technical assessment of particular objects. The chosen section is situated on cadastral area of town Sedlčany in the Central Bohemia region. Its length is 1.973 kms and there is located 5 water management objects reaching to the flow profile of the watercourse. The data for this dissertation has been gained by the Czech State Administration of Land Surveying and Cadaster. It is about the digital relief of the 5th generation of aerial laser scanning. The laser rays are not capable of penetration the water surface, and thus describe the shape of the water-sources bed. So the tool called CroSolver was used to dig the water-sources bed. Then the hydrodynamic model has been created in program called HEC-RAS. From the results of hydrodynamic model then was evaluated the real water-technical state of the object. The outgoing data (dots defining the flood range to the surroundings) was after then inserted to the program ArcMap. Here the flood lines and from them the flood zones were created based on the particular series of the flows.
