The Drobotfor basin is situated in the eastern part of Tutova Colinas, in the Bacau County and it is tributary of Zeletin River. The watershed drains a land area of 87.61 sq. km and is characterized by an elongated shape on north-south direction. It has a length of 32.3 km with differences regarding height and relief fragmentation of each sector and a maximum width of 4.25 km in the inferior sector. The land is heavily degraded, especially by erosion. The high torrential degree in the basin denotes the possibility of concentration large amounts of water from rainfall with thunderstorm fallen character with great importance in the area of modelling of the relief. In this study, using a GISbased approach, the SCS-CN method has been applied to the Drobotfor watershed in order to peak runoff rates for a uniform rainfall. There have been taken into consideration the relevant spatial and hydrological characteristics.
