ABSTRACT

The goal of the contribution is to present a comprehensive and complex possibility of modelling the runoff processes for a given part of Bratislava city. The complex approach consisted of mutual integration of results of partial mathematical models – rainfall-runoff model, sewage system model, 1-D hydrodynamic modelling of open channel flow together with partially covered flows, 2-D hydrodynamic modelling of flooding the town residential area. All modelling works have been done in DTM coming from aerial photography. According to the modelling process, appropriate preventive measures have been designed and realised in the territory, i.e. detention reservoirs in the mountain region above the urban region and determination of their effect on runoff process of flush floods as well as other technical measures in the covered channel system have been performed.
