What Causes Beach Erosion?
Unfortunately for beach lovers and owners of high–priced beach-front homes, coastal erosion in any form is usually a one–way trip.
According to

Coastal erosion is the wearing away of land or the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage.

The state of the beach affects everyone's lives

What is Beach Loss?

 Beach grass com­mu­ni­ties often create sand dunes that mitigate coastal ero­sion and flooding risks stem­ming from rising sea levels caused by climate change.

 Climate change has resulted in increased coastal erosion, flooding and rapid salinisation of groundwater.

SUSTAINABLE SHORELINE EROSION CONTROLS

Removing sand and other materials from beaches and dunes due to tidal storm surges and construction purposes causes massive beach erosion damages and land loss of seashores, thus destroying the natural heritage of the coast and reducing the vibrancy of the tourism industry.

Uprooting vegetation from coastal areas destabilises beaches and clearing sites inland results in increased soil and dirt particles being washed offshore and smothering coral reef systems.

Beach nourishment–also referred to as beach replenishment or sand replenishment–describes a process by which sediment (usually sand) lost through longshore drift is replaced from sources outside of the coastal ecosystems..

Pumping sand onto the coastline helps maintain wide beaches for tourism and property protection, but some scientists say pumping sand also damages a fragile and often overlooked ecosystem for fish and birds.

BEACH EROSION ACTION PLAN

The creation of a comprehensive program of restoration and maintenance of beaches will maintain the current surface and in some cases it will increase the beach areas. This will also favor the ecological balance between the flora and fauna of the coast region in relation to urban development.

A technique called beach scraping

Beach scraping essentially is using a bulldozer to push sand up from the low tide mark to the dunes, which can possibly slow severe beach erosion and protect damaged dunes.… read more

  Your provider of sources for consulting services in the field of bioengineering , water quality and habitat restoration utilizes terms such as biotechnical erosion control, biostabilization or soil–bioengineering – often used synonymously with bioengineering.

None of these erosion methods is right for all situations. Erosion prevention should match the type of coastal erosion, and lakeshore environment, to the control channels.

Nonetheless there are methods we can help to slow down the rate of coastal degradation  via these beach renourishment and erosion control protocols.

These Best Management Practices (BMPs) supply the three types of standard Coastal Strategies:

Vegetative

Vegetative coastal erosion control is the use of native plants and trees to stabilize the soil near the shore. Cattails and reeds can be used in the water to lessen the effects of wave action. These plants are very hardy and can withstand changes in lake water levels.
Using ecological principles to determine vegetation and other materials to soften the edge, known as soft shoreline engineering, this technique stabilizes the shoreline and can create wildlife habitat, cleanse stormwater, improve public access and make the shoreline more attractive.

Combination

Structural : Within this category are steel bulkheads, timber bulkheads, vinyl bulkheads, concrete walls, stone masonry walls, stone revetments, and stone reinforcement.
Non structural shore erosion control projects are those that use bioengineering to create protective vegetative buffers.

Yet the degradation of "coasts" is threefold

Coastal Shoreline (Non–Structural & Structural).
Freshwater(streams, river deltas,lakeshore)
Ocean & Intertidal areas

Draining into coastal shorelines is an important subset of waterways. Most are degraded biologically, physically and chemically and therefore require appropriate methods to be developed for health assessment.

Methods

Pembrokeshire archaeologists are racing against accelerating coastal erosion to uncover an ancient cemetery.

Stones from cist (stone coffin) graves can be seen eroding from the bay's low cliffs and archaeologists are recording what remains before it too is washed away by the sea.
