Abstract
In this research, two categories were used to investigate the effect of the change of clarion surface water of Khash plain. The data on 2010 to 2020 obtained from the Liz Hydrometer Station on the Syanjah River Khash Plain, on the other hand, the base rainfall data was obtained from the Khash Station. Based on the measured regression model, the base period of the relationship between Dubai and precipitation at the Khash basin level was modeled. With the implementation of the SDSM statistical microscale model, the simulated rainfall values were obtained in the statistical period of 2020-2040, under two lines of release 4.5 and 8.5, which was used as an input to the regression model for remodeling in the climate change period. The results showed that in the period of climate change 2040-2020, despite the fact that the rainfall of the Khash basin has increased in the cold months of the year, the simulated runoff of the period 2040-2020, in both RCP4.5 release trajectories and RCP8.5, has had a decreasing trend. The results indicated that the climate change period 2020-2040, in the RCP4.5 release, had reduced about 0.02 cubic meters per second to the base period, and in the RCP8.5 release track, this was a decrease of 0.016 cubic meters per second.
