Coastal Design and Restoration

Coastal Design and Restoration
Coastal engineering applies a mixture of civil engineering and other disciplines to create coastal solutions for areas along or near the ocean. In protecting coastlines from wave forces, erosion , and sea level rise , marine engineers must consider whether they will use a “gray" infrastructure solution - such as a breakwater, culvert, or sea wall made from rocks and concrete - or a “green” infrastructure solution that incorporates aquatic plants, mangroves, and/or marsh ecosystems. [22] It has been found that gray infrastructure costs more to build and maintain, but it may provide better protection against ocean forces in high-energy wave environments. [23] A green solution is generally less expensive and more well-integrated with local vegetation, but may be susceptible to erosion or damage if executed improperly. [24] In many cases engineers will select a hybrid approach that combines elements of both gray and green solutions. [25]
