Through an extensive hydrogeophysical investigation at the geodynamic station in Membach, Belgium, we aim to estimate hydrological variations in the surrounding area. Our focus is on integrating gravity and ambient seismic noise measurements to develop a detailed hydrological numerical model at a local scale. The first step of the study is to examine the correlations between the geophysics and hydrological observations of the area. Then, we employ stochastic sampling methods to examine subsurface parameters, allowing us to reproduce diverse observables such as gravity anomalies, seismic velocity changes, and water balance variations best. This comprehensive approach enables us to obtain a more accurate understanding of the hydrological processes occurring beneath the surface. By combining ambient seismic noise with gravimetry, we aim to address current instrumental limitations in hydrology, particularly for studying deep and complex critical zones. These critical zones are essential for understanding the interaction between the Earth's surface and subsurface, as well as the variation in water storage. Our research anticipates that this integrated method will provide more precise and detailed insights into hydrological dynamics, ultimately contributing to improved water resource management and a better understanding of geophysical signals influenced by the water cycle.
