A Multiscale Approach for Monitoring Groundwater Discharge to Headwater Streams by the U.S. Geological Survey Next Generation Water Observing System Program in the Neversink Reservoir Watershed, New York

Summary

Groundwater that drains to surface water via seeps and springs is generally referred to as “discharge.” Groundwater discharge is a primary component of stream base flow, or streamflow that occurs between storms, periods of snowmelt runoff, and periods of quick soil drainage. Streams that gain groundwater as they flow are common across glaciated regions such as the Delaware River Basin, and the hydrogeologic mechanisms that control exchanges of surface and groundwater are complex (Figure 1). Because of this complexity, groundwater discharge rates are rarely evenly distributed throughout stream networks, which may instead be dominated by locations of preferential discharge along riparian wetlands, streambanks, and the streambed (Briggs [...]
