Short summary
The Eramosa River flows along a fractured sedimentary bedrock aquifer with large subsurface channel features. This study examines the potential for groundwater–surface water exchange beneath the fractured bedrock riverbed and the impacts of seasonal and intraseasonal flow system transience on the geoelectrical properties of the rock. Our results will have implications to the conceptual understanding of groundwater–surface water interaction within fractured bedrock river environments.
