This publication co-authored by Q. Wei, A. Brookfield, and A. Layzell, investigates how water management decisions influence streambank stability by altering subsurface hydrologic conditions. This study leverages HydroGeoSphere (HGS), coupled with the surface water operations model OASIS, to address long-standing challenges in linking reservoir operations, groundwater pumping, and hydrologic dynamics to the physical mechanisms driving streambank failure.
