Abstract:
... Managed aquifer recharge (MAR) will play an increasingly important role in solving water scarcity. The performance of MAR systems depends primarily upon local hydrogeology. Greatest opportunities for improvement in the implementation of MAR systems lie in the targeted application of conventional and advanced technologies to improve aquifer characterization. Surface geophysics (e.g., VES, TDEM, and ...

Abstract:
... The artificial recharge of transboundary Genevese groundwater uses treated water from the Arve River to recharge the aquifer. This system has been in place since 1980. Although the system has demonstrated its worth and has helped to offset the excessive use of the 1960s and 1970s by raising the average water levels in the aquifer by more than 6 m, the region is still subject to water supply proble ...
