| The synthetic unit hydrograph is commonly used for the derivation of a design hydregraph. The existing Snyder's equation for the syntheses of unit hydrograph was found to give relatively a flat hydrograph in comparison with observed hydrograph and a revision is required. HEC-1 model is used to simulated observed hydrograhp in the South Han River basin and results are used as an input for the regression. The basin is subdivided into small drainage areas and the synthesized hydrograph is routed through channels. After the calculated hydrographs are compared with observed one, the synthesized hydrograph of each subbasisn is revised and the new snyder's equation is derived . The revised equation gives rapid increase of discharge in rising limb and larger peak. |
