Coastal Erosion

Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms.

Coastal Erosion

Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soils, and/or sands along the coast. All coastlines are affected by storms and other natural events that cause erosion; the combination of storm surge at high tide with additional effects from strong waves—conditions commonly associated with landfalling tropical storms—creates the most damaging conditions. The extent and severity of the problem is worsening with global sea level rise, but it differs in different parts of the country, so there is no one-size-fits-all solution.

A beach breach is defined as an accumulation of sediment–usually sand or gravel–that occupies a portion of the coast. The active beach, the area of loose sediment subject to transport by wind, waves, and currents, is divided into three regions: the backshore, the foreshore, and the offshore. The backshore is the area above the high tide line that is only affected by storm waves and storm surges. The foreshore is the area between the high tide line and low tide line that is affected by waves and currents. The offshore area located beyond the low tide line is only impacted by waves.

I hope that helps clarify what a beach breach is.

Biodiversity is important to identify precursory signals (e.g., coastal morphodynamics, changes in sea surface temperature resulting in coastal erosion, soil moisture, and snow cover) as they are associated with Carbon Capture and Storage (CCS) (or carbon capture and sequestration) and ocean acidification. Research of Coastal Erosion and Coastal Erosion Zone Management has determined global sea–level rise, the loss of sand dune plant habitats, earthquakes, floods, and sudden shifts in river courses exacerbate many of these geohazards.

COASTAL EROSION IS AGGRAVATED BY MAN–MADE STRUCTURES.

Coastal erosion is a result of a number of geologic, oceanographic, and atmospheric factors, including the relative sea level rise due to climate change. Typically, these armoring structures are erected when coastside sea rise threatens the beachfront. The creation of a comprehensive bio–based living shoreline plan of restoration and maintenance of beaches will maintain the current surface and in some cases will increase the coastal foreshores: coastal geomorphology (Estuarine, Coastal, and Shelf Science).

Erosion prevention should match the type of coastal erosion and lakeshore environment, to the natural and constructed channels, and culverts controlled by outside forces. Uprooting vegetation from coastal areas destabilizes beaches and clearing sites inland resulting in increased soil and dirt particles being washed offshore and smothering coral reef systems. Environmental Awareness: Concerns about the damage being done to the ocean by pollution a.k.a. environmental destruction / toxic waste dump serve to prompt an Environmental Compliance Audit: a key component of the coastal challenges of environmental management.

TOURISM

Rising sea levels could engulf beaches and other natural resources in coastal areas, damage cultural destinations, and flood tourism infrastructure, costing businesses enormous amounts of time and money, warned Dang Thi Bich Lien, deputy minister for Culture, Sports and Tourism, at a recent conference.

“LIVING SHORELINE”

In the wake of disappearing (eroding) beaches in coastal areas, living shorelines are a creative and proven approach to protecting tidal shorelines from erosion. The technique consists of planting native wetland plants and grasses, shrubs, and trees at various points along the tidal water line. Soft Engineering is a new GREEN approach to shoreline stabilization. These VE (value engineering) technologies are used to prevent surface erosion and accelerate the establishment of vegetation. New legislation in Maryland specifies “living shoreline” as the preferred type of erosion control as they place great importance on the health of dunes and beaches. read more Shoreline Renourishment–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.. Beach grass communities often create sand dunes that mitigate coastal erosion and flooding risks stemming from coastside sea rise caused by climate change. Accelerated shoreline changes, sea–level rise (SLR), and land loss have resulted in vanishing coasts, increased coastal hazards related to climate change (both natural and man–made disasters), flooding, and rapid salinization of groundwater.

Coastal geomorphologists look at climate change and its effects, such as temperature and sea–level rise, predicted by the United Nations Intergovernmental Panel on Climate Change, playing a role in accelerated coastal erosion. Geomicrobiology has shifted, either from a pattern of accretion to one of erosion.

COASTAL CONSTRUCTION

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. 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.

EMERGENCY SAND

 “Beach Scraping” is the transfer of sand from the lower beach to the upper beach (within the beach system), usually by mechanical equipment, to redistribute the sand to parts of the beach above the tidal level. 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

BIOENGINEERING

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.

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.

ECOLOGICAL ENGINEERING IS A BREATH OF LIFE FOR MARINE ECOSYSTEMS

 It’s important to identify precursory signals (e.g., changes in sea surface temperature resulting in coastal erosion, soil moisture, and snow cover) associated with carbon capture and storage.

“Oxygen is essential for many life forms. But we don’t often give it the attention it deserves because we assume that it is always there. While oxygen is ubiquitous in our atmosphere, it is not necessarily the case for many bodies of water like rivers, lakes or even oceans. Here a lack of oxygen can result in significant impacts on the ecosystem like founrd in Sweden.”

YET THE DEGRADATION OF “COASTS” IS THREEFOLD

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. Nonetheless, there are methods we can use to slow down the rate of coastal degradation via protocols preventing erosion scarps from faulting. According to the IPCC, CO2–induced global warming will be net harmful to the world’s marine species.
