The Suha River basin is the right tributary of the Moldova River and occupies a mountain area and high and small depressions (such as: Gemenea, Negrileasa, Stulpicani–Frasin), which favored the increasing concentration of the population in this area. Because of the increased basin population, issues related to the formation and evolution of flow regime in the Suha River basin are particularly important. The years 1975, 1981, 1984, 1991, 2005, 2006, 2007 and 2008 have registered significant flood insurance rates (20%, 10%, 5% and 2%) being generated by rainfall with torential character and very high intensities. For a better management of the emergency situations arising from the rapid increase of the water level, in this paper we analyze a new method proposed by Smith (2003), in order to realistically assess the potential index of flood transmission. Based on data obtained from the hydroclimatic network of hydrometrical stations in the basin (Gemenea 1, Gemenea 2, Slatioara 3, Stulpicani and Valea lui Ion), we intend to estimate the potential index of flood transmission identifying areas of vulnerability to floods in the Suha River basin. The estimation of the index is based on the analysis of the following physical-geographical factors: precipitation, soil texture, slope and land use. The index values will be obtained by processing the data, which results from the analysis of spatial distribution of the factors taken into account, in GIS software. By generating the map on the estimation methods of the distribution of the index of potential flood resulted as Suha basin presents a medium risk of flood production on 75% of its surface.
