Description :
This article presents a procedure, by which to identify small drainage basins vulnerable to the propagation of abrupt flood waves, and hence to flash flooding, in response to short-duration episodes of very intensive rainfall. Long known for such local flooding events, basins in the Carpathian were described by reference to a large number of physiographic characteristics of importance to the generation of abrupt flood-wave phenomena. Features found to be associated with an enhanced probability of such flash flooding (thanks to faster transformation of precipitation into outflow) included: basin area, slope and changes in elevation along the valley, but also land-use structure, physical properties of the soil and the configuration and density of the river network. The results of multidimensional analysis provided for the identification of types of basin vulnerable to the flood-wave formation in question. – (BJ)
