Estimation of groundwater storage depletion using GRACE data in Karbala Region, Iraq

In the present study, changes in gravity data for period from (2004) to (2020) have been used monitoring groundwater storage (ΔGWS) Karbala province. Groundwater change values were found by subtracting soil moisture extracted "Global Hydrological Models (GLDAS)" the(ΔTWS) obtained GRACE. The results showed that rate of is approximately -17 cm, with an annual trend about -1.039 cm / year (2020). These was compared ground available observation well Dibdibba Formation city 2011 2015 which represents part GRACE data. A equal -1.2cm observed and -0.94 field. This study proved can be improving management any place where there paucity also remote sensing technology very effective tools give preliminary predictions areas measurements are lacking a short time low cost good accuracy.
