The United Arab Emirates (UAE) is situated within an arid zone where the climate is arid, and the recharge of the groundwater is very low. However, rapid expansion, population growth and agriculture activities have negatively affected these limited water resources. The shortage of water resources has become a serious concern due to the over-pumping of groundwater to meet demand. In this study, a combination of time-lapse measurements of microgravity and depth to groundwater level in selected wells in Al-Ain city was used to estimate the variations in groundwater storage. Relative gravity measurements were acquired using the Scintrex CG-6 Autograv from March 2018 to March 2019. The purpose of this study is to estimate the groundwater storage changes in the shallow aquifer based on the application of microgravity method. The microgravity changes from March 2018 to March 2019 at four water wells located in Al-Ain are ranging from 128 Gal to 151 Gal referenced to base station (UAEU, E-4 building) data of March 2018. The calculated water storage changes from microgravity changes at four wells during the same period are ranging from 3.05 m to 3.60 m, which had a good correlation with observed water level changes at four wells from Falaj Hazza (Al-Ain, UAE) (R2 = 0.67). Water storage changes can be estimated from microgravity changes using this equation: ΔS = 0.0239 Δg.
