Ecological Coastline Replenishment

Ecological Coastline Replenishment 

Throughout the southeast, shoreline restoration is a continual necessity. Designing the most resilient coastline requires thorough planning and ecological considerations. For a beach renourishment project, Engineers calculate the sediment amount needed to enhance shoreline resistance to storms and wave surges. The sediment needs are analyzed for shoreline resistance and enhancements of ecological habitats. Dunes offset both. Dunes are a natural wave break, are sand storage, and host ecological habitats. The best way to protect the dunes and mitigate erosion is through analyzing the foreshore and berm; making sure there is enough sediment or the shoreline is sloped in a way that offsets waves as much as possible before reaching the dunes. 

Dunes also aid in the creation of ecological habitats by adding vegetation. The vegetation acts as a structural anchor through its roots and water absorption; and encourages ecological habitats. Not only are ecological habitats protected, but coastal homes and tourism are also preserved through beach renourishment. Extending beaches defers wave energy and protects uplands from flooding. Preventing erosion and flooding enables the tourism and beach economy to thrive. According to the U.S. Army Corps of Engineers, more than half of the nation’s economy is dependent on the coastline. Through the design of sediment placement beaches can be restored, can enhance ecological habitats, and be enjoyed for years to come.
