Abstract

The 2011 massive flooding in Chao Phraya, Thailand prompted its government to revise its river management plan. H08 Model was one of the models chosen for this purpose due to its ability to incorporate reservoir operation in modeling. This study serves as base step of this purpose by calibrating four globally-determined parameters to suit the local conditions. The optimized parameter sets resulted to very good hydrograph fits in the daily, monthly and annual scales from 1981-2004 and 2010-2011. Nash-Sutcliffe coefficients at monthly and annual scales are 81% and 85%, respectively. Flood peaks corresponded well with that of the naturalized observed.
