Abstract

Summary

Hydrogeophysical tools allow characterizing the heterogeneity of karsts and evidencing groundwater storage in their subsurface. A permanent gravimetric monitoring highlights seasonal variations in gravity that can be related to vadose zone effects after the discrimination of the saturated zone signature with direct measurements. A surface ERT monitoring improved with daily borehole-to-surface measurements through the vadose zone allows identifying preferential flow paths. Groundwater storage variation is then monitored by time-lapse inversion of the ERT datasets.
