N2 - The quantification of hydrogeological properties has been traditionally restricted to intrusive measurements. This limitation has led to a growing number of geophysical techniques applied to hydrological studies, included in a field known as “Hydrogeophysics”. The mass variation linked to hydraulic head change generates gravimetric anomalies detectable with improved microgravity instruments. Therefore it leads to a new monitoring strategy. Very recent papers have shown the capabilities of hydrogravimetry, but all of them used independent codes for flow and gravity. The use of separate codes leads to problems with heterogeneous domains or data transfer. This paper describes how the fluid extraction in an unconfined aquifer is coupled in a single program to the corresponding gravimetric simulation of its anomaly. In addition we explain how to estimate a transient parameter, the specific yield, under steady flow conditions.
