flooding

Prykarpattia is one of the areas in Europe most prone to floods. Recent environmental research predicts a trend towards an increase in these dangerous phenomena in the Carpathian region of Ukraine. The analysis of the losses caused by floods in Lviv region shows that the allocation of funds for the elimination of the consequences of floods is growing every year. It is necessary to introduce comprehensive regulation of riverbeds, taking into account the development of channel processes and forecasting possible changes under the influence of hydraulic structures.

Aim of this research is to determine the area of land flooding according to a reasonably chosen hydrological model for a complex section of the Dniester River at the place of transition from the foothill to the plain with complex meandering and significant shifts of the river. Methods. The method of investigation of flooded areas as a result of water rise to a certain level has been processed.

The diversity of landscape conditions in the territory of Ukraine is caused by the peculiarities of the geomorphological structure, zonal climatic, hydrogeological and seismic factors, which generally determines the area of distribution of exogenous geological processes (EGP). Most of these processes, namely landslides, karst formations, flooding and erosion of territories, mudflows are activated under natural conditions.

On the basis of geodesic pretentious novelties the transversal types of river-bed are built r. Stryj, nearbyс. Stryj. The analysis of results of supervisions is given by possibility to draw conclusion about the processes of transfer and accumulation gravel the masses in a river-bed and lower lyinga valley Stryj.
