Abstract
The parameters of Nash's conceptual model of Instantaneous Unit Hydrograph, n and k, are estimated by the moment method from the rainfall and runoff data in 18 watersheds of drainage area ranging 53.7 to 1,361 sq. km. Then, these parameters are represented in terms of watershed characteristics by F-test and multiple correlation method. The unit hydrographs by this study are compared with the unitgraphs obtained from the recorded runoff data and agreements are good. The results imply that unit hydrographs in ungaged watersheds can be derived by watershed characteristics only through Nash's model.
