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)....
