Abstract
The paper presents an application of a distributed hydrological modelling framework in a Romanian flash-flood-prone watershed. The physically-based model TOPOG was tested at a sub-daily time step for the Voinesti catchment, a small watershed located at the western end of the Curving Sub-Carpathian Mountains. An analysis of the basin behaviour, as well as an evaluation of the model performance, was performed, and a practical gauging procedure was designed in accordance with the need of using the model under this type of circumstances (small basin, no sophisticated gauging). The importance of such a gauging procedure lies in the perspective of using the once-gauged model for flash-flood warning systems in this type of basins.
