| Abstract | Drought has beena prominent hazard in parts of Thailand, and climate change is threateningaggravation of droughts, due to alteration of water balance under possible increase of evapotranspirationand greater variability ofrainfall. In view of this, thisstudy evaluatesand compares (1)Characteristics of Past (1976-2010), Near Future (2021-55) and Far Future (2056-90) droughts, and (2) Spatial distribution of characteristics of past and futuresignificantdrought episodes within the drought prone Upper Mun River Basin, Thailand.Standardized Precipitation Index (SPI) and Palmer Drought Severity Index(PDSI)were employedfor this study, the former detects drought based on rainfall only, while the latter considers the effect of temperature and Available Water Capacity (AWC) of soil as well. Future climate data serving as input of calculating future SPI and PDSIwasacquiredfrom bias-corrected BCC-CSM 1-1, MIROC-ESM-CHEM and GFDL-CM3rainfall and temperatureunder two climate change scenarios, RCP 4.5 and RCP 8.5, obtained from NEX-GDDP dataset.It wasconcluded that (1) Sufficiently large temperature increase underRCP 8.5scenario could, in late 21stcentury,reverse the main rainfall-driven reduction trend of drought characteristics, and (2) Under a warmer climatein the future, AWC would be more significantly influencing PDSI, with greater magnitude of PDSI droughts in areas with larger AWC, informing that future drought mitigation efforts should go beyond soil conservation practices |
