Abstract

CLIMATE CHANGE causes the change in temperature, rate of evapotranspiration, soil moisture, wind speed, and temporal and spatial variation in precipitation. These factors will lead to changes in hydrological parameters, such as groundwater level. According to the important role of climate parameters in water resources management, in this study HADCM3 model and A2, A1B and B1 scenarios are used to predict the climate parameters. For the statistical DOWNSCALING of atmospheric general circulation model data, LARS-WG model is used as one of the most famous random weather generator models. Also prediction of groundwater levels changes in TASUJ BASIN was done by time series models in R software for the period of 2013-2022. The results revealed a decrease in rainfall as well as higher temperatures in the A2 scenario compared to the other scenarios. Changes in temperature and precipitation are similar in A1B and B1 scenarios. In all three scenarios, maximum rising temperatures and the highest percentage of precipitation decrease will occur in the months of June, July, August and September which coincides with the peak of groundwater use for drinking, agricultural and environmental purposes. Also the cross-correlation showed that the impact of rainfall on groundwater levels has a 2 months lag. Due to the CLIMATE CHANGE and assuming the persistence of the existing conditions of exploitation from groundwater in TASUJ BASIN, the cumulative decline of groundwater level in a 10-year period is predicted as 7.85 meter below the baseline in 2002. These FORECASTs should be taken as a serious warning for water management in this region so that to prevent human and environmental disasters.
