Description: A Ph.D. Assistantship is available (beginning January 2015) to examine interactions between plants, sediments, and hydrodynamics along wetland shorelines in the Delaware Estuary, US. The objectives are to quantify linkages between waves and marsh scarp dynamics and biophysical processes and sediment deposition along the marsh edge. This research is part of a large collaborative project to assess changes to estuary morphology, including wetlands, over time and particularly due to channel dredging. Research techniques will include field surveying using Real Time Kinematic GPS, deploying pressure sensors for wave and water level measurement, measuring sedimentation and accretion rates, and plant structure and morphology. The student will develop an independent research project w
