Continuous records of monthly rainfall and mean monthly or monthly evaporation, as well as physical parameters were the inputs to the model. The model parameters were initially given from previous experience and later adjusted so that the computed hydrographs reasonably agree with the observed hydrographs. The model was then used to predict  hydrographs to compare the results with the observed ones.  The obtained results were fairly reasonable for the Nan river  basin at Sirikit Dam and the Yorn river basin at Kaeng Luang but were not so good for t he Khwae Noi river basin at Lum Sum. This may be due to large areal fluctuation of precipitation and small number of rainfall  stations in the basin. Although individual year peak and volume of runoff could not be predicted accurately, total volume of discharge for several years could be predicted with fair accuracy.10aRunoff10aHydrologic models1 aArbhabhirama Anat, eChairperson1 aSelvalingam, Selvadore, eCo-Chairperson0 a Tawatchai Tingsanchali,  eExamination Committee2 aAustralia Government, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno. 929  3Full-Textuhttp://203.159.5.9/ait-thesis/detail.php?q=B22645
