This thesis deals with determining the flood lines and hydrotechnical assessment of the Říčanský water flow and objects that interfere with the flow profile. Hydrotechnical assessment preceding hydrological study of catchment. The basis for this work was digital model relief Czech Republic, which obtained from Airborne Laser Scanning. This method is considered to be of the most accurate methods for altimetry data obtained, but the near-infrared laser beam used in this method cannot penetrate water masses. The result of this problem is error as the extracted cross sections lose a significant portion of their flow area. These errors can be removed to recess the channel using specialized software Crosolver tool. For hydrotechnical assessment is used hydrodynamic model in HEC-RAS. On the basis of results are determined the flood line for N-years flows (5-years flow, 20-years flow and 100-years flow). The final part of this work deals evaluation of hydrotechnical assessment Říčanský water flow, object and floodplains.
