Vigorously influenced to Thai researcher, GAME-T data base has been successively produced such enormous research projects. Public domain system modeling is one of them thus were producible created under GAME-Chaophraya project.
Selective basins were upon Ping river, Nan river and Pasak river which drainage areas occupied 1,500, 10,000 and 14,000 square kilometers respectively. Two of them, situated in mountainous area, were unregulated studiousness while the largest basin was regulated by Pasak Cholasit dam site. Essential data approached from GAME-T data base which were two stations at Ping river, nine stations at Nan river and eleven stations at Pasak river.
Hydrologic Respond Unit (HRU) and Streamflow Hydrograph Separation and Analysis Program (HYSEP) were intensified for flood hydrograph and base flow methodology. According to model calibrations and verifications, admissible results with more than seventy percentage of correlation efficiency performed an ensuing accuracy in these appropriations. Innovative Geoinformatic-system execution could illustrate precisely synchronism with public domain model SWAT2000.
