DETANGLING TANGLEWOOD: CHARACTERIZING THE VERTICAL, HORIZONTAL, AND LONGITUDINAL CONNECTIVITY IN A COASTAL PLAIN HEADWATER STREAM
Water movement through watersheds drives the chemical, physical, and biological functions of downstream aquatic ecosystems. However, there are systematic gaps in our understanding of watershed storage and connectivity dynamics that limit our ability to effectively manage downstream waters, especially in low-relief regions like the southeastern Coastal Plain. Here, we work to address this knowledge gap by characterizing the vertical, horizontal, and longitudinal hydrologic connectivity of a headwater stream (90ha) in central Alabama. We measured vertical flux in groundwater wells installed above and below clay confining layers, and measured horizontal flux by organizing wells into hillslope transects capturing three distinct hydrogeomorphic units with varying degrees of stream incision. We then performed seasonal network surveys visually quantifying longitudinal connectivity through the network length. Our initial results suggest that vertical connectivity is constrained by clay layers; horizontal connectivity is related to stream incision, where incised streams have higher water table elevation gradients and greater water flux; and longitudinal connectivity reflects seasonal patterns of wet-up and dry-down, with greater connectivity in the wet spring season. This work provides an initial characterization of headwater processes that will impact downstream water quality in Coastal Plain watersheds.
