ABSTRACT

In Eastern Romania there are conditions for flash floods occurrence like the intensity and duration of rainfall, the topography, soil condition, coverage of the terrain, especially in small ungauged basins with no functional hydrotechnical and land reclamation works. When proposing mitigation measures it must be taken into account the unforeseeability of the place, local scale of the event, and particularly the violence of the phenomenon, as well as the very short response time and the great threat to human lives. The costs are a very important and sensitive aspect taking into account that the case study covers a poor Romanian area. Therefore non-structural measures could be more appropriate and feasible than the structural ones. The paper is focused on identifying the most easily and efficiently mitigation measures to be implemented based on flash flood hydrological modelling for Pojoratan subbasin.

Keywords: flash floods, non-structural measures, ungauged basin.
