The main objective of this study is to determine the unit hydrograph of the Voineşti Basin, located in the north-west of Dâmboviţa county, at the border between the Curvature Sub-Carpathians,GeticSubcarpathians and Getic Plateau. Voinesti Basin shows climatic and hydrological characteristics specific to watershed that favors the production of fast velocity floods. The unit hydrograph is important for: (i) the design of various hydrotehnical constructions and (ii) determination of flooding hydrographs for a given storm data. The applied method statement consists of: (i) separation between direct runoff and the base flow (using a graphical method), (ii) determining the net precipitation, (iii) determining the unit hydrograph ordinates (iii) the selection of unit hydrograph which correspond to a uniform precipitation evenly distributed to basin. The study has been performed based on the analyses of the storm flow events from 1997-1998. The selected hydrograph was the one corresponded to august 2-nd 1997.
