| Abstract | The applicability of rainfall data collected from the closest
rain gauge station to derive unit hydrographs in small watersheds was tested. Average unit hydrographs from thirteen sample watersheds in the range of 18 to 243 square kilometers from Northern, North Eastern, Central and Southern Thailand were derived. Runoff records from forty-two typical storms were analyzed. A new
approach of deriving unit hydrographs without using rainfall data was tested. After studying the special characteristics of the derived unit hydrographs, a simple four parameter double triangle
model was fitted. The hydrograph parameters were expressed in the form
P = KPa Pb Pc Pd
1 2 3 4
by four measurable watershed characteristics using multiple
regression analysis. |
