| Abstract | A mathematical model is developed in order to predict flood- flows from rainfall of small watersheds. The model is a modified version of the USDAHL - 70 Model and is applied to sub watershed D of the Kog-Ma basin, in Chiengmai, Thailand. Twenty-five input parameters which describe the characteristics of the watershed are first estimated from the available hydrologic records and topographic maps. These values .are adjusted until the simulated hydrographs are reasonably matched with the observed hydrographs. The parameters are then used to predict twelve storm hydrographs and compared with the observed values. Results from this investigation indicate that the model gives very satisfactory reproduction of hydrographs, especially single peak hydrographs. However, the. simulated time to peak flows usually is greater than the observed values. |
