Protective Coastal Beaches and Dredging

John Huang, Ph.D., PE and John Poullain, PE

This three-hour online course provides general guidelines and practices for the development and construction of beaches and dunes for the protection of coastal lowlands and restoration of eroded beaches. The course provides an overview for planning and utilization of dredged material as an alternative method for beneficial dredge disposal. Beach and dune creation with dredged material consists of filling, raising and protecting areas that are subject to wave attack and periodically or permanently submerged. Remedial actions and activities performed at the construction sites must comply with federal, state and local regulations to protect water quality, fish and animal habitat.

The student will understand the procedures for planning, developing and restoring beaches and dunes with dredged material and the benefits and disadvantages. Design factors including types of dredge material and equipment selection, timing of material placement and methods for placement are discussed. The student will also become familiar with the techniques used to construct beaches for wildlife habitat and measures to avoid adverse results.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
