Design for Prevention of Beach Erosion at Presque Isle Beaches, Erie, Pennsylvania. Hydraulic Model Investigation
Presque Isle Peninsula, Erie, Pennsylvania, is a recurved sand spit with a lakeward perimeter of 9 miles that extends a protective arm around Erie Harbor. The peninsula provides 11 recreational beaches facing Lake Erie which are part of a State park that occupies almost the entire peninsula and contains an ecological reservation and numerous recreational facilities. Over the past 150 years, the integrity of the peninsula has been threatened by erosion of the beaches due to a decreasing sand supply, and numerous efforts to halt this erosion have been ineffective. A 1:50-scale (undistorted) physical hydraulic model was constructed to aid in evaluating the use of detached offshore breakwaters as a preventive measure against shoreline erosion. The model reproduced a 9,400-ft length of shoreline which included State Park Beaches 4, 5, and 6. These beaches contained a section of shoreline with an existing groin field and a reach of shoreline with few shoreline structures as it was desired to study the interaction of the proposed structures with both types of beaches.
