Microgravity

Abstract

Gravity survey data can provide quantitative information on changes in the mass of water within an aquifer, which has obvious water resources value. The technique is particularly useful for unconfined aquifers that experience changes in water levels caused by pumping or recharge (natural or artificial). Unconfined alluvial aquifers are important water sources in many arid regions, so gravity surveys have applications for water-resources investigations in these regions.
