Geomorphological Model of Overland Flows in Gamasiab

In order to identify the geomorphological factors of overland flows in Gamasiab basin, twelve physiographic and Geomorphic variables of sub-basins related to the flood were studied through the use of multiple regression within a 25 year period. The analysis of the data indicated seven significant and important factors. These variables are: Coefficients of Gravelious and run off slope of the main channel , slop of the basin, length , the area of the basin, and mean height of the basin. The final model was significant at a=0.01 level.
