COMPARATIVE, MULTI-PARAMETER MODELLING, AT A BASINAL AND SUB-BASINAL LEVEL, FOR FLOOD VULNERABILITY, IN TECUCEL WATERSHED

Abstract

Of all phenomena which lead, through their manifestation, to material damage and loss of human lives, floods are the most devastating. They present a high degree of danger, both in frequency and intensity, but also by the high value of the damage produced. Romania has faced numerous floods in the past decades, of which the ones that took place in the Eastern region are of most significance in Siret watershed and Prut-Barlad river basins. To prioritize the interventions, the deployment of forces, as well as funds for flood defenses, first the zones and the sub-basins which are the most vulnerable must be identified. The purpose of this work is to develop an analysis at a sub-basinal level, which will take into consideration the most important morphometric parameters that are influencing floods, to obtain a comparative, relevant and understandable result, in order to achieve several cartographic materials that are easy to interpret and present to the authorities capable to intervene in such situations. The proposed model can be applied to any hydrographic basin that has a sufficiently detailed digital elevation model (DEM), in order to generate significant results.
