IDENTIFICATION OF THE POTENTIAL FLASH FLOODS RISK AREAS IN ROMANIA USING PHYSIOGRAPHIC METHOD
Abstract
In recent decades the increase of the frequency of flash-flood conditions requires a correct identification of potential flood areas where these hydrological risk phenomena appear in Moldavian Plain. To identify the basins and localities exposed to flash-flood was used physiographic method. This method allows the opportunity to identify the river basins with the concentration of water from precipitations in less than 6 hours. Through successive sorting of the basins which may generate the flash-flood was identified 95 sub-basins, of different orders, vulnerable to this type of hydrological risk which may affect 155 rural and urban areas. Reporting the results obtained for identification of the potential flash floods risk areas to the historical floods highlights the presence of 12 areas with significant risk of flooding in the Moldavian Plain generated by heavy rains over 100 mm in few hours.
