Programing and priorities in watershed management demand of variety of data such as water yield and fluctuation of it.This subject especially in tributaries are very important.Most costraction in rivers need water yield data in different probability of occurrence.Average water yield in different return periods for estimating of river Capacity and managing of small and large dams utilization and downstream farms are necessery.The result of this project used for estimating of water yield.In this research the data of hydrologic stations in a common base year for station chose and then mean annual flow calculated.Homogenos watersheds based on morphometric data has done.Based on mean annual flow the regional analysis done and discharge of return periods 2 to100 years by statistical distribution obtained and best statistical distribution Chose.By using of hydrological and morphometrical data such as mean annual discharge ,area,slope ,forest cover persent and precipitation with discharge the equation for each homogenous region in each return periods presented.
