Dear Deepak Patle , are you reffering to the specific storage as aquifer capacity? The specific storage is one of the physical proporties that charcterize the capacity of an acquifer to store a/o release groundwater. They are often determined using some combination of field tests (e.g., aquifer tests) and laboratory tests on aquifer material samples. Also these properties can be determined using remote sensing data derived from Interferometric synthetic-aperture radar.
The aquifer information or characteristics which are evaluated by most aquifer tests are:
Hydraulic conductivity;
Specific storage or storativity;
Transmissivity.
Additional aquifer characteristics depending on the type of aquifer, include:
