- W2113895970 abstract "In basement catchments of subhumid West Africa, base flow is the main component of annualstreamflow. However, the important heterogeneity of lithology hinders the understanding of base flowgeneration processes. Since these processes are linked with water storage changes (WSCs) across thecatchment, we propose the use of hybrid gravity data in addition to neutron probe-derived water contentand water levels to monitor spatiotemporal WSC of a typical crystalline basement headwater catchment(16 ha) in Benin. WSC behaviors are shown to provide insights into hydrological processes in terms of waterredistribution toward the catchment outlet. Hybrid gravimetry produces gravity change observations fromtime-lapse microgravity surveys coupled with gravity changes monitored at a base station using a superconductinggravimeter and/or an absolute gravimeter. A dense microgravity campaign (70 surveys of 14 stations)covering three contrasted years was set up with a rigorous protocol, leading to low uncertainties (<2.5 lGal)on station gravity determinations (with respect to the network reference station). Empirical orthogonal functionanalyses of both gravity changes and WSCs from neutron probe data show similar spatial patterns in theseasonal signal. Areas where storage and water table show a capping behavior (when data reach a plateauduring the wet season), suggesting threshold-governed fast subsurface redistribution, are identified. Thisobserved storage dynamics, together with geological structures investigated by electrical resistivity tomographyand drill log analysis, make it possible to derive a conceptual model for the catchment hydrology." @default.
