Runoff generation, flood mapping in an urban area, and extreme inflow simulation in a reservoir
Brych, Karel ; Dittrt, František ; Eliáš, Václav ; Kafková, Dagmar ; Tesař, Miroslav
The aim of this paper is to present the contribution and conclusions of the Institute of Hydrodynamics to the findings of the project. The first part deals with the relation of runoff of water from the soil into the transport collector determined by hydropedological methods to the discharge in the closing profile of a small forest catchment. In the second part the flood mapping in an urban area is studied. The third part concerns the influence of flood situations on water quality in reservoirs.
Landscape digital database for flood modelling in Zamberk
Brych, Karel ; Dittrt, František ; Eliáš, Václav
Flood hazard map of the urban area of Zamberk were developed using one dimensional HEC-RAS modelling. A digital terrain model (DTM) was prerequisite for solving the problems in the Arc View environment. The ZABAGED/1 state map altas on a 1:10 000 scale was used as the DTM. This system has a limited altimetric resolution, therefore the elevation data in the river channel was repaired.
