Implications of Hyporheic Flow on Temperature-Based Estimates of Groundwater/Surface Water Interactions

Abstract

The hyporheic zone has received significant attention in recent years due to its role in regulating the physical, chemical, and biological processes that buffer fluvial systems at a variety of scales. The exchange of water through the hyporheic zone is also important for the regulation of stream and streambed temperatures. Recent research has utilized stream and streambed temperatures to quantify groundwater discharge to streams using a variety of methods, including one-dimensional analytical solutions for vertical flux across the streambed interface. The presence of lateral flows, including hyporheic flow, will cause uncertainty in these analytical solution results. In this study,
