| Abstract | The Kiew Kor Mah reservoir has problems in the current operation. There are flooding in downstream area many times. The previous rule curve needs to develop for reduce flood damage and to supply irrigation demand. The optimization process was applied the Harmony Search algorithm for determine the optimal rule curve. The aim of this study to improve reservoir operation. There are three parts in this study. Firstly, to develop rule curve by using Harmony Search algorithm. The rule curve from Harmony Search algorithm can gain the best benefit (compare with previous rule curve and existing operation). Secondly, presents the future climate projection in the Wang River Basin which considered three climatic variables: precipitation, maximum temperature, and minimum temperature. Three RCMs were selected to address climate model uncertainty. The Linear downscaling method technique was applied for correcting the data from climate models with observed climate data. The future climate was projected for three future periods: the 2020s (2010–2039), 2050s (2040–2069), and 2080s (2070–2099) under RCP4.5 and RCP8.5 scenarios based on the baseline period (1979–2005). The future precipitation may increase during the dry season (November to April) and decrease during the wet season (May to October) under both RCP4.5 and RCP8.5 scenarios. Average annual maximum and minimum temperatures are expected to increase in the future. Lastly, assess water resources especially water inflow by using The Hydrologic Modeling System (HEC-HMS) model. Results from HEC-HMS model shows that the average annual discharge may decrease in future for both stations under climate change scenario. |
