Increasing salinization is the reality for coastal landscapes worldwide. Saltwater travels over the land, under the ground, and through surface water channels. However, hydrologists have studied the pathways of over, under, and through separately, limiting the full understanding and prediction of where salt is delivered in coastal landscapes. Human modifications additionally alter these pathways and in turn, alter the delivery of salt into freshwater landscapes. Holistically studying the hydrology of SWISLR is needed where the pathways over land flow, underground, and through surface water channels are studied together with the alteration of human modifications included.
This group is writing a perspectives piece to present a conceptual framework that calls for this integrated study of water flow and human modifications. Multiple case studies will be highlighted in the paper as reasons to study SWISLR holistically and as potential ways to use the conceptual framework. The paper will wrap up by discussing the future of our coast and recommendations for studying SWISLR hydrology. In today’s webinar, a few potential case studies were presented. Greg Noe talked about the “Through” and the heavily modified Savannah River. Justine Neville presented a case study of saltwater intrusion into small man-made channels in southeast North Carolina due to flow control structures. Alex Manda showed us projects measuring the salinity of agriculture fields in Coastal North Carolina due to the connectivity of agriculture drainage canals. Lastly, Marcelo Ardón shared his experience with saltwater intrusion in the Albermarle-Pamlico Peninsula in coastal North Carolina in a restored forested wetland. Additional proposed case studies are Southern New England, the Eastern shore of Virginia, and the Gulf Coast.
