ABSTRACT. - Hydrological features of the lower Prut floodpain . In the lower Prut floodplain, between 1981 and 1985, the most important transformations of the natural ecosystems and hydrological regime have been generated by the dams and embankment works. These were undertaken in order to increase the surface of land used for agriculture or fisheries. Consequently, during long periods of drought, some wetlands are dry every year, and the periods on drought are followed by irregular flooding periods. The liquid flow of the River Prut is influenced by the rainfall and the functioning of the Stânca Costeşti Reservoir. Statistical processing of the data from Oancea Hydrological Station resulted in the average water flow during 1979 - 2006, which is 96.39 m3/s, with the variation is between 26.1 m3/s and 381 m3/s.
Key words: lower Prut floodplain, average water flow, floods, embankment works,
