| Sumario: | <p>Monitoring the water movements in karstic areas is a fundamental but
challenging task due to the complexity of the drainage system and the
difficulty in deploying a network of observations. Gravimetry offers a valid
complement to classical hydrologic measurements in order to characterize
such systems in which the recharge process causes temporarily accumulation
of large water volumes in the voids of the epi-phreatic system. We show an
innovative integration of gravimetric and hydrologic observations that
constrains a hydrodynamic model of the Škocjan cave system (Slovenia).
We demonstrate how the inclusion of gravity observations improves water mass
budget estimates for the Škocjan area based on hydrological observations
only. Finally, the detectability of water storage variations in other
karstic contexts is discussed with respect to the noise performances of
spring and super-conducting gravimeters.</p> |
