The increase in the world's population has increased the amount of water consumption. Understanding the impact of climate change on various aspects of water resources can create methods to reduce or adapt to these effects. Therefore, the present study aims to investigate the impact of climate change on the vulnerability of the groundwater aquifers of Taibad Plain through Nistor's inference matrix method and using the GFDL-ESM2M fifth report model under the two release scenarios RCP4.5 and RCP8.5 in the period from 1991 to 2100 was done. For this purpose, De-Martonne's aridity index and available water were used. The results of the available water index showed that the lowest amount of available water is located in the eastern part of the region, and in the future, the trend of decreasing available water will spread to the west of the region. De-Martonne's aridity index results also showed that most of the dry areas under both scenarios are located in the eastern part of the basin. The results of Nestor's inference matrix showed that the areas with a very high effect on the recharge of groundwater aquifers are located in the north and southwest parts, and the regions with a very low effect are visible in the eastern part of the area. Also, the areas with a very low effect are without any special trend, which indicates the poor recharge of these parts, and climate change in the future has not impacted this issue. Parts with low impact also have an increasing trend. Also, sections with medium and high effects show a decreasing trend. These conditions exist in both RCP4.5 and RCP8.5 scenarios. In general, the change in climate parameters until the year 2100 will reduce the recharge potential of underground aquifers in about 55-60% of the studied area by at least one class.
