Maximum Flow Variablity and Flood Potential in Trotuş Catchment Area. This paper investigates the maximum flow specific features and flood potential of Trotuş River. Statistical analyses (employed to determine frequencies, exceeding probabilities and tendencies) have turned to account the maximum, monthly and yearly discharge series recorded during a period of over 30 years by 21 stream gauging stations scattered over the catchment. The study shows, on the one hand, the spatial and temporal variability of maximum flow and on the other hand the flood occurrence potential on a monthly and annual scale, meaning by important floods the ones whose discharges are higher than defense specific stage (attention stage, flood stage and danger stage). The obtained results show an important interannual variability of the maximum flow and a high flood potential during the interval May – August, with a peak in July. Even though the last years have witnessed important floods in this catchment area, there have been identified no significant tendencies either in the variability of the annual maximum discharges or in the yearly number of floods.

Keywords: maximum discharge, floods, Trotuş catchment area.
