FLOOD HAZARD ASSESSMENT AND MONITORING USING GEOGRAPHIC INFORMATION AND REMOTELY SENSED DATA

摘要

Floodings are an important risk in many areas around the globe and especially in Romania In the latest years floodings occurrred quite frequently in Romania, some of which isolated, others were affecting wide areas of the country's territory. The paper assumes a modem approach for the flooding risk indices, associated to the physic-geographical, morpho-hydrographical and vulnerability characteristics of a region, in view to establish a methodology which should further allow to determine the flooding risk, using representatives indices at a scale compatible with a synthetic representation of the territory. There are stressed the facilities supplied by the Geographic Information System (GIS) and the remotely sensed data to manage flooding during their characteristic phases: before, during and after flooding Accent is laid on the pre and post-crisis phases. The application was developed for the Arges hydrographic basin in Romania, a critical area, keeping in mind that it withholds many localities, including the capital and also important economic centres.
