An innovative and effective way to accomplish this is to create an artificial sand retention reef offshore under the waves. That's why we are asking the GHAD to amend the current CPD to include installation of a permanent offshore sand-retention reef. This would be a cost-effective way to reduce the erosion rate by up to 50%, and possibly more.

What Are Artificial Dunes and Dune Nourishment? A dune is a hill, mound, or ridge of sediment that has been deposited by wind or waves landward of a coastal beach. In Massachusetts, the sediments that form beaches and dunes range from sand to gravel- and cobble-sized material. An artificial dune is a shoreline protection option


Artificial dunes are engineered structures reproducing the form of natural dunes, often in a chain-like manner. They are built with sand brought from an external source area and shaped into dunes using bulldozers, dune nourishments or other means.


Fact Sheet 1 discusses artificial dunes and dune nourishment. With this technique, sand, cobble, or other sediment (of appropriate size) is brought in from offsite to build a new dune (i.e., mound of sediment) or add to an existing dune to protect inland areas from erosion and flooding. Dune projects are appropriate for almost any area with ...


An artificial dune is a shoreline protection option where a new mound of compatible sediment is built along the back of the beach, seaward of the area to be protected. Artificial dunes may be called cobble berms when larger pebble- and cobble-sized materials are used.


But bulldozed dunes are not proper sand dunes. They lack the ideal sediment layers and get sand from where it is needed. In the short term, these artificial sand hills will be destroyed by the elements. Because dunes protect inland areas from swells, tides, and winds, they must be protected and defended like national treasures.

Advantages and Disadvantages of Soft Shoreline Stabilization. Alternative soft stabilization approaches can offer many benefits over typical hard stabilization structures. Often these approaches are referred to as living shorelines because they offer added ecological benefits. Some of the benefits of soft stabilization approaches include:


Injecting or pumping water into an aquifer for storage and use at a later time is known as Aquifer Storage and Recovery, or ASR.. This is the concept of ASR: during times of plentiful water, extra water can be withdrawn from a river (or other source) and then injected and stored within an aquifer.

Dune regeneration involves taking action to build up dunes and increase vegetation. This helps to strengthen the dunes and prevent coastal retreat. New sand dunes can be created to protect from coastal flooding. Often, marram grass is planted to hold the dunes together. Wooden boardwalks can be built to encourage people not to walk on the dunes.
