ABSTRACT. Study regarding delineation of flood hazard zones in the hydrographical basin of the Someş River, border area. The hydrological studies will provide the characteristic parameters for the floods occurred for the calculus discharges with overflow probabilities of 0,1%; 1%, 5%, 10%. The hydrologic and hydraulic models will be made by using the hydro-meteorological data base and the topographical measurements on site; them calibration will be done according to the records of the historical floods. The studies on the hydrologic and hydraulic models will be necessary for the establishment of the carrying capacity of the riverbeds, for the delimitation of the flood plains and for the detection of the transit discharges at the hydro-technical installations, but also for the establishment of the parameters needed for the structural measures’ projects. These will be based on the 1D and 2D unstable hydro-dynamic models. Therefore, the users would be able to assess the proposed measures and the impact over the river’s system; of course with the potential combination of the 1D and 2D.
The main objectives followed by the project are:
• identification of the river basins or river sub-basins with flood risks;
• regionalization of the flood hazard;
• presentation of the main flash floods occurred during the last 30 years, which induced floods;
• assessment of the consequences of eventual flood over the population, properties and environment;
• the establishment of the protection degree, accepted for the human settlements, for the economic and social objectives, for the farm areas, etc.;
Keywords: cross border cooperation, flood hazard zones.
