Abstract. Some aspects regarding the flash flood analysis and the natural flood risk map of Someș Plain. The knowledge of the characteristic elements of flash flood is of particular importance in designing reservoirs with multiple functions, in designing and placing structures, but, especially in preventing and warning the population in case of flooding, taking into consideration the fact that the area is subjected to river flows, hence to the greatest disasters and also damage caused by this phenomenon. To achieve the calculation of flood parameters, data referring to periods of floods were collected from nine gauging stations from across the Someș Plain, related to four main watersheds, Tur, Someș, Crasna, and Ier, with good presentation in the territory. To have a common calculation period, in order to compare results, a single range was chosen for all stations for 26 years (1979-2004). The natural flood risk map represents the documentation that includes(in writing and graphics) the flooded areas at different probabilities at producing floods, indicating damage to property and humans for the administrative units affected by floods. The natural flood risk map is part of the county planning documents and it is detailed in the general, regional and community urban plans.
