Research 1


We are modifying a Nitrogen Loading Model (NLM) to determine total nitrogen (TN) loads to coastal lagoons on Delmarva from watersheds with contrasting agricultural land-use and population sizes. For this work, we are collaborating with  colleagues at the University of Maryland and the Virginia Institute of Marine Science; our portion of this project is focused on measuring the losses of N that occur through a variety of processes during transit through the watershed. This natural remediation of N loading is a powerful “ecosystem service” that should be estimated and considered in management scenarios. We are also evaluating the impact of selected best management practices (BMPs) on nutrient delivery by groundwater.
