Shoreline Stabilization North Carolina’s barrier islands, a 325 mile-long string of narrow sand islands that forms the coast of North Carolina, are one of the most beloved places to visit and live in the United States. With the winds and tides, we change yearly. Look back on a map from twenty years ago and you can see how the Outer Banks has changed. The lines have shifted, new inlets have opened and closed, and overall the famous barrier islands are getting narrower. Projects and experiments are in place to help its structure remain the same, saving our precious beaches. Shoreline stabilization is defined as the use of structures, vegetation, or land management practices to provide protection of a shoreline from future or existing erosion. …show more content…
It also promotes wildlife habitation. As we see around here, phragmites and spartina stabilize our shorelines all year round: although not exactly pretty in some people’s opinion. Vegetation is an excellent choice for areas where it can be fenced off to avoid foot traffic ripping up fragile young roots. It is a low cost option that offers eco-friendly and economic friendly uses. Due to plant root systems being fragile in the first few years of growth it must be watched and maintained carefully. Once the eco- system is in place many people can enjoy the variety of wildlife that will move in. When implementing vegetation as a stabilization technique it needs to be chosen with care. Native plants are preferable as they are already proven to be able to survive in the conditions present. Invasive species must be chosen as a last ditch answer because some can adapt to any conditions and take over thus out competing any native species that are already …show more content…
Normally when a living shoreline is used to stabilize shoreline, vegetation and hard structures such as bulkheads or rip-rap are used. To create a living shoreline a base is set down, usually a bulkhead or rip-rap but sometimes softer materials such as biologs are used, and then a layer of oyster shells, sand, and vegetation are layered on top of that. The oyster shells and hard base attract oysters and other mollusks to colonize the surface. Over time as the vegetation grows deeper root systems, and the mollusks bind them to the hard surface, it creates a stronger structure. The big downfalls to these are few, the biggest being the cost of research needed to successfully integrate and keep a healthy community of oysters or other mollusks. Living shorelines should also be kept away from foot traffic as the rocks and shells can be quite dangerous, and for the first few years the whole bed is unstable. Fishing these beds could also cause damage so it is wise to keep fisherman from the
However, if any action is taken to defend the coastline, if you hinder in nature's course of beach erosion, there will always be after effects resulting from unnatural intrusion. This proves that any sea defence could prove a problem especially with the land owned by Nation Trust. Nevertheless if you could prove to the owners of the land to the extent of which erosion is taken place and show them how much LSD is affecting the area, action may well become a better option.
Investigating the Geographical Processes that are Affecting the Physical and Built Coastal Environment There are three geographical processes that are affecting the physical and built coastal environment, they are; erosion, deposition, and transportation. Erosion is the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the earth’s surface, this is mainly caused by wind, running water, and waves breaking on the coast. Deposition is the depositing something or the laying down of matter by a natural process. Transportation is when sand is moved along the coast by long shore drift. At North Cronulla beach erosion is evident.
Semaphore Beach is affected by many factors such as natural processes and human impacts including marine litter and the discharge of stormwater. Therefore, several plans have been employed to ensure that the coast is supported through the method of counteracting erosion. However in the future, many management strategies have been put into consideration as well as the environmental, economic and social impacts as well as the predicted consequences. These impacts include traffic related incidents, noises and air pollution and the disruption of wildlife and the erosion of dunes. A method that should be considered for future management of the beach is the use of a concave sea wall, although efficient, this structure would be quite costly. Without the use of coastal management, Semaphore Beach would be unsupported, therefore negatively being affected by a variety of
There are many different types of coasts that exist throughout the United States. The south shore of Long Island has a unique types of coast known as a barrier beach. Barrier beaches are long narrow land forms that are composed of sand and other lose sediments. These sediments are brought together by the actions of waves, currents and storm surges. Barrier beaches are subject to constant changes by the same forces. Sand is constantly eroded in one area an deposited in another. Barrier coasts are important for a number of reasons; they protect the mainland of Long Island from the open ocean and flooding during storms, for recreational use and the unique ecosystems which exist on barrier beaches.

Over the past 100 years the Louisiana coastline has suffered greatly from biotic, abiotic, and anthropogenic factors. The abiotic factors include things such as hurricanes or overnutrition that influence the surrounding biota. The biotic factors that contribute to coastal erosion are things like the immigration invasive species and the emigration or extinction of local flora and fauna that help preserve the wetlands. Additionally, there are anthropogenic factors such as pollution that can have strong negative influences on the abiotic and biotic factors of the wetlands. Each one of these factors cause ecological disturbances to the wetlands at a frequency and intensity that is unmanageable for the local flora and fauna. There are currently certain measures that are being taken into consideration to slow or stop the erosion of the Louisiana coastline.
... consider some ideas of what can be done to further enhance the management of the coastal issue. Using the research action plan, I aim to acquire a sophisticated understanding of longshore drift, coastal management and implementations of coastal issues, through the research action plan. Most importantly, I will include various diagrams explaining how the process of longshore drift occurs and what implementations it has on coastal environments, accompanied by an explanation of how the issue is being managed, a detailed outline of the geographical processes involved and a discussion of the impacts of the issue and why it is important.
This vegetation also provides much cover for fish. The aquatic plants provide a great source of food supply and act as a nursery for young fish (“Native” par. 5). Vegetation serves many purposes in fish habitat; besides keeping fish safe. It also helps keep the lakes clean. Aquatic plants cycle the water and help absorb pollutants. Another great benefit of these aquatic plants are that they help hold sediment and the banks of the lakes in place while providing oxygen into the water (“Invasive” par. 7-8). Unfortunately invasive species are destroying such vegetation. The Common Carp or “Cyprinus carpio” is one such fish that is causing great damages to lakes all around the world.
Geologically speaking, Louisiana is a very young state. Environmentally speaking, Louisiana is a very fragile state. Louisiana has always been dependent upon the nutrient rich deposits from the Mississippi River to build up the land. Centuries ago the Mississippi River periodically changed its course, building up Louisiana one delta at a time. The erosional forces of the Gulf of Mexico and annual hurricanes depleted Louisiana’s coastline, but the mighty Mississippi River would replenish the land losses. Such is the relationship that forces of nature have with one another. Place mankind in the mix, and the relationship becomes stressed and dysfunctional. The present day Louisiana coastline is a mere shadow of its former self. Let’s look at how Louisiana came to its current demise and what is being done to rectify the situation.
Coastal erosion is a growing problem along the Gulf Coast. Louisiana is one of the coastal states most affected by coastal erosion. Ninety percent of wetland loss in the nation occurs in Louisiana, losing 25-35 square miles per year. At that rate, Louisiana will lose 640,000 more acres by 2050. Many factors contribute to this land loss, such as rising sea levels, subsidence, hurricane storm surge, cold fronts, and human interference. Cold fronts and hurricanes can both have detrimental consequences on the coast of Louisiana (Zhang 2004) (Restore or Retreat 2012). This research shows whether cold fronts or hurricanes have a larger effect on coastal erosion. The researcher will describe how historical and current satellite imagery help in determining the changes in the Louisiana coast. Based on previous research, the researcher believes that hurricanes have more of an effect on coastal erosion than cold fronts due to the high winds and storm surge.
Native plants in any given area have adapted to all the other organisms in a given area and genetically diverse ecosystems are generally maintained.
Surfers, swimmers and sunbathers use beaches for recreation. People fish off beaches for food. Since many people take their vacations at the beach, lots of beaches in tropical locations are important to their country’s economy. Entire cities, regions and countries depend on the money tourists spend while visiting the beach. Beaches are naturally very dynamic places, but people try to control them and build permanent structures, such as houses, restaurants, shops and hotels, on or near the shore. The natural erosion and deposition of beaches becomes a problem. Beaches con disappear over time, or even over night during severe storms. Beaches are areas of loose sediment (sand, gravel, cobbles) controlled by ocean processes. Most beaches have several characteristic features. First are offshore bars, which help protect beaches from erosion. Next is the foreshore, which rises from the water toward the crest of the next feature; a berm. On low-lying shores, dunes form behind beaches. Dunes look like rolling hills of sand and are blown into place by the wind. New, smaller dunes are often changing shape as the wind continues to affect them. Waves and currents move the accumulated sediment constantly creating, eroding and changing the coastlines.

Everyone one has a different background weather it’s a matter of principles, religion, or culture. Marriage is a legal union between two people who promise to love and care for each other for life. There’s a big process that comes to play when you make a decision of marrying your significant other. In the generality of the marriage process everyone has I different perspective of getting to know our partners. The biggest of them all being, if living together before marriage is better than marriage first. My personal belief and principles are that marriage should come first before moving in with the person. You should be sure that your partner is the one you want to share life with, make sure that your comfortable around them enough to marry them, and that you prove you both have enough respect for each other to be sure that what you got is real enough to marry them before moving in.
