The Analysis of Flooding Risk in Bahlui Basin. The hydrographic network developed in the south-central part of the Moldavian Plain, in the area between Prut and Siret rivers, is represented mainly by the basin of Bahlui. Although the basin is over 80% hydrotechnically managed (there are over 150 reservoirs larger than 5 hectares, tens of square kilometers of dammed or drained areas and so on), in some extreme situations (as in August 2005 or July 2008) a series of inundations occurred, affecting settlements and agricultural terrains, with damages estimated to over 2 million lei. The analysis of the flooding risk has been conducted based on the techniques offered by Geographical Informational Systems (digital elevation model realized after 1:25000 topographic maps or 1:5000 topographic plans, vectorial strata representing elements of the natural or modified landscape) and by remote sensing (aerial photos). To exemplify the methodology used in the study of flooding risk in Bahlui basin, we have chosen two areas affected by this phenomenon: the town of Târgu Frumos (the confluence area between Bahlueţ and Rediu) and Lungani area (on the valley of Goeşti brook).

Keywords: flood risk, GIS, vectorial analysis
