In a context of global change and increasing anthropic pressure on the environment,
monitoring the Earth system and its evolution has become one of the key missions of …

The karst environment is one of the most challenging in terms of groundwater, engineering
and environmental issues. Geophysical methods can provide useful subsurface information …

Limits on the long-term stability and accuracy of a second generation cold atom gravimeter
are investigated. We demonstrate a measurement protocol based on four interleaved …

This paper highlights the efficiency and complementarity of a light package of geophysical
techniques to study the structure of karst Unsaturated Zone (UZ) in typical Mediterranean …

Large portions of the world are characterized by shallow soil underlain by weathered
bedrock or cemented soil horizons. The implications of this substrate condition for …

This review covers basic theory and techniques behind the use of ground-based gravimetry
at the Earth's surface. The orientation is toward modern instrumentation, data processing …

Epikarst exerts a strong control on run‐off generation in karst regions, but it is still unclear in
karst regions. Our study aimed to demonstrate the effect of epikarst on near‐surface …

Time‐lapse microgravity surveying combined with absolute gravity measurements is used to
investigate water storage changes in a karst aquifer of∼ 100 km2 area. The survey consists …

In this paper we present the potential of a new compact superconducting gravimeter (GWR
iGrav) designed for groundwater monitoring. At first, three years of continuous gravity data …

Karst spring/stream discharge reflects the global configuration of the aquifer. However,
quantitative description of the aquifer structure such as effective porosity (n eff) and water …
