Abstract:
To examine the effects of two climatic parameters of average rainfall and average annual temperature on water resources status toward the population parameters in seven grade-2 watersheds, located in Persian Gulf and Oman Sea, the observation data of 180 synoptic stations in the proposed watershed and historical data of the CORDEX project for the 20-year statistical period (1986-2005) considering RCP2.6, 4.5 ,8.5 climate scenarios were used in this study. Then, the EC_EARTH, CNRM and GFDL climate models were used for the upcoming periods of (2006-2030) and (2031-2050). Finally, the ability of each model to fit the water stress index (based on the lowest error with the base course) for each watershed was studied. The results of this study showed that the all three climate models (EC_EARTH, CNRM and GFDL) predicted MOND and KOL-MEHRAN watersheds, respectively, as the highest and lowest water resources status in relation to population parameter in upcoming periods of (2..6-2.30) and (2031-2050) and under RCP2.6 ,4.5 and RCP8.5 scenarios, relative to the observational water stress index .
