WA-85-20 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology, 1984 Lumped representation of distribution function approach is replaced by the spatial heterogeneity of the processes and parameters. The model parameters can be computed distributivity from basin geomorphology. This is the advantage to apply the developed model to ungauge watershed. Exponential, bivariate exponential and gamma distributions are studied and compared. The obtained results are fairly reasonable for Lam Chi Long and Huai Yang basins. There are small differences of values of parameters of three distribution functions which are acceptable. This may be due to the procedure to estimate storage depth are still under investigated and information of time distribution of daily rainfall is not known. Although the total volume of predicted discharge are less than observed ones, the shape of hydrograph can be predicted with fair accuracy of runoff with several peaks.
