Development of flood boundary of urban areas using HEC-RAS software.
Original language description
Flood hazard maps of urban areas in the Orlice Valley were developed using HEC-RAS software. The calculated boundary of the flood extension area was fitted to the observed boundary by optimizing Manning`s roughness coeficient. These parameters were thenused to compile a flood boundary map corresponding to 100-year flood.A digital terrain model (DTM) is pre-requisite for map compilation in the ArcView enviroment. The ZABAGED/1 state atlas on a 1:10000 scale, available for selected regions of the Czech Republic, is usually being used as the DTM. This system contains land-surface elevation data in a vector format. Taking into account the limited altimetric resolution of ZABAGED, we used geographic maps on a 1:1000 scale derived from regional aerial photography.
