This film explores some of the Hard Engineering solutions used in coastal process management. Explore the different ways in which these solutions work, and the positive and negative aspects of their use.

The links course at Doonbeg, owned by the Trump Organisation, received permission for two sea barriers of 630m and 260m in length — a year after plans for a 2.8km wall were rejected. Residents and environmental groups objected, saying the wall — which is designed to protect the golf course from coastal erosion — could alter the coastline at other points and harm wildlife. “It’s disappointing. We should be altering the golf course, not the coastline,” Green Party leader Eamon Ryan.

This paper demonstrates that antecedent topography played a very important role on the coastal evolution of
Rio Grande do Sul (RS) in Brazil during the Holocene. By modeling the last 9 ka of sea level change using the
general morphology of the present shelf as the substrate over which barriers have translated a successful re-
construction.

...a rescue plan that would involve installing “reef modules” offshore and creating onshore groynes through sandbagging. However, it is not yet clear what option the Shire of Gingin, which will receive the money, will pursue.

The 450-metre long TRESBP jetty and adjacent control centre are central to the sand bypassing system. The jetty is located on Letitia Spit, south of the Tweed River mouth. At the jetty, sand is drawn in by submerged jet pumps along the jetty pylons; this northwards drifting ocean sand is intercepted before it accumulates at the Tweed River entrance. The jetty can only draw in the amount of sand that waves and ocean currents bring to the jetty.

To understand Tweed Sand Bypassing and why the project was necessary, it is important to have an understanding of coastal processes. The coastal zone can be viewed as an intricate system made up of different components that are all interconnected. The three main components of the coastal system are:
the underlying geology such as coastal headlands and near shore islands;
the nature and abundance of the coastal sediment; and
the extent to which these controls are acted on by the waves and wind.

Three different types of ports are analyzed:
in an "isolated environment"; with a river mouth in the sea and with the mouth of a large estuary.

Managed realignment is the most cost-effective solution, as it allows the natural process, using the areas effected as beaches and wetland.

Beach erosion has become a headline issue as it continues to be a growing problem on coastlines around the world. Whether the shore is sheltered or exposed, elements like currents, waves, and sea level changes play significant roles in causing erosion. As a solution-based provider, GEI Works offers several different products to help control coastline erosion and prevent further deterioration along your shores. Read on for several different beach erosion solutions, or contact one of our specialists to help you determine which method is best for your coastline erosion application.

Many homeowners experiencing loss of property due to erosion unwittingly contribute to it by installing seawalls. When incoming waves hit the hard surface of the wall, energy reflects back and moves down the coast. Often, an adjacent homeowner will experience increased erosion and bank scouring after a neighboring property installs a seawall. This will often lead that neighbor to install a seawall themselves, transferring the problem further.
