I don't have Piezometric data, and exploring GRACE data for this and till now, I think we need to define other models to do so. Is there any other option to estimate this?

Dear Naeem,
There is increasing interest in using GRACE (Gravity Recovery and Climate Experiment) satellite data to remotely monitor groundwater storage variations; however, comparisons with ground-based well data are necessary to validate satellite data processing, especially when the study area is close to or below the GRACE footprint.
Here is a paper that can be useful.

Dear Naeem,
We used Grace satellites. Here is another potentially useful article:
Chinnasamy, P., J.A. Hubbart, and G. Agoramoorthy. 2013. Using Remote Sensing Data to Improve Groundwater Supply Estimations in Gujarat, India. Earth Interactions, 17:1-17.
Best of luck!

Dear Naeem Bhai
Recently, a Pakistan based study was compiled to estimate groundwater storage variations http://ieeexplore.ieee.org/document/7498655/
May be helpful for you
Dear All, Thank you for your valuable replies. I am looking deeply into it, and will see if I can come up with a model to directly measure water table depth from GRACE by incorporating other parameters.
