Buffalo District to Study Sediment Movement Along Presque Isle Peninsula

摘要

To study the movement of sediment along the Presque Isle Bay shoreline in Erie, Pennsylvania, the U.S. Army Corps of Engineers Buffalo District is conducting a particle tracer study to determine if material dredged from Erie Harbor Shipping Channel can be used to nourish and enhance the shoreline growth on the peninsula. Presque Isle Peninsula and Erie Harbor are located on the southern shore of Lake Erie. The peninsula is a recurving sand spit that forms and protects the harbor. The peninsula is home to Presque Isle State Park, which is home to seven ecological zones or landscapes, and dune and beach plants that are found no where else in the state. The peninsula formed naturally thousands of years ago and is constantly being reshaped by wind and waves. Approximately every five years, the sediment dredged from Erie Harbor, about 200,000 cubic yards, is typically placed in an open-water disposal area in the lake three miles offshore.
