Abstract: 

At many basins sub of Sefidrood dam the first hydrometric and climatologic data of existed stations were gathered, tested, repaired and finally physiographic parameters were measured. The selected sub-basins were divided into hydrological homogeneity groups by method of hierarchical cluster analysis based on physiographic specifications and annual precipitation. The borders of clusters were then clarified by canonical discrimination function and the annual water yield discharge with different return period was estimated by suitable probabilistic function. The effective factors to model annual discharge recognized were area and average height of sub-basins by method of Principle Component Analysis (CPA). Finally the best and easy equation of estimation of annual discharge was produced only based on area parameter.
