ABSTRACT:
For determining design discharges for hydraulic structures, it is necessary to determine the unit hydrographs of the corresponding basins. In Turkey, suitable data to determine the unit hydrograph of a basin are not easy to find, therefore unit hydrographs are usually determined synthetically. Coefficients used in the synthetic unit hydrograph determination are taken from studies made for specific areas in the world. In this study, unit hydrographs are determined for four subbasins in northwest Anatolia. Using the characteristics of these unit hydrographs and of their subbasins, Snyder's synthetic unit hydrograph coefficients are determined, and relationships between coefficients and basin characteristics are searched.
