The present study focuses on the runoff calculation in the Monoroştia Basin, Arad County, Romania, during the historical flash flood in august 2010. On the basis of the collected geospatial data, the hydrologic parameters are computed in a GIS environment, which are subsequently used as input for the rainfall-runoff model. The SCS loss method and the SCS transform method were used for the runoff calculation by the means of a Hydrological Modelling System and the gage weights precipitation method so as to reflect the spatial characteristics of precipitation. The results consist of unit hydrographs for each subwatershed outlet, where monitoring activity doesn't exist.
