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.
