I have seen  that some work has been done using GRACE data related to groundwater level monitoring.

Ground based resistivity data is more popular than that of the gravity surveys and has been widely used.

I think GRACE data can provide some constraints on the terrestrial water storage (TWS) and groundwater movement in large-scale basins. Furthermore, airborne gravity maps or field-based measurements could be useful in delineating subsurface faults and the role they play to facilitate or impede the groundwater movement in aquifer systems.

 Thank you Dr. Zaki for your answer.

hi

First, you have accentuated using micro gravity data,  thus the data sampling distance is small and dense and the target (groundwater aquifers) volume is small or medium and shallow. The GRACE data is not micro gravity data and the gravity map which is generated by GRACE data include the long wavelengths of causative body. The GRACE data is suitable for the regional studies. The resolution of GRACE data is low.

The micro gravity data is the best method for determination of depth and approximate

volume of groundwater aquifers or aqueducts, because of high density contrast. As for the morphology of under study area, using resistivity in many place Is not possible, specific if the aim is 3D modeling.
