Coastal Erosion And Informative Essay Outline: Coastal Louisiana

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

The characteristic warming climate of the Late Pleistocene and Early Holocene resulted in rising sea levels which contributed to the formation of the various deltas in the New Orleans area (Dunbar, Britsch, 2008). The natural formation of these deltas produced coastal wetlands that represent 30% of coastal wetlands currently in the United States (Cigler, 2007). In addition to these wetlands, the Mississippi River was surrounded by substantial forest growth (Pabis, 1998).

There are 2 types of beaches. One is erosion dominant and the other is deposition

* The Skillion, mainly the headland and rock platform, which is part of a preserved area of land known as “the Haven” which also contains the rugby oval. The man type of erosion that affects this is from the sea.

The more coastal erosion there is, the higher the chance is for saltwater contaminating freshwater resources and the salt from the ocean can cause soil to be uninhabitable to plants (Again this can affect agriculture). Coastal erosion is not only an issue for water resources, it’s also a direct issue for the communities. The communities on islands lay very close to the coast and important infrastructures are one of them. Islands cannot get all of their resources from the local farmers, so they import it via plane or boat. The problem with that is the airports and ports are all on the coast. Coastal erosion has the power to ruin airport runways and docks of the harbors and ports; this means that eventually communities will be starved of basic necessities and there will be no way of getting in basic needs. Not only will airports be ruined, so will our tourism industry. Coastal erosion will eventually ruin the beaches that attract tourists. Island communities depend on the tourism industry because that industry brings in a lot of money every year. Without tourists, communities will struggle financially. Lastly, the ecosystem of the islands will suffer the

tides. There are also many programs which help to ensure the stabilization of dunes, these include the planting of new vegetation to combat erosion, fencing and designated

Louisiana is a state consisting of about 4,523,628 people. This number taken prior to Hurricane Katrina that occurred in 2005. As of 2015, the estimated population of Louisiana is 4,670, 724. The area of the state of Louisiana is about 43, 562 square miles. With its neighboring states of Texas, Arkansas, and Mississippi, Louisiana is located within the southeast part of the United States. The state’s first geologist was Francis V. Hopkins. Along with his assistant, Colonel Charles H. Lockett, Hopkins published the first topographical and geological maps of Louisiana. Louisiana has a variety of natural resources. Some examples of these natural resources are forests, salt, oil reserves, natural gas, and sulfur.

The processes of erosion are wind, water, mass movements, glacier ice, and ocean waves. Wind erosion occurs when gusts of wind carry smaller sizes of sediment to different places. Wind erosion typically takes place in “...mostly in flat,

I would have to say trying to stabilize the different shorelines can possible contribute to its erosion over time. The various techniques for helping to preserve our n shorelines could possibly include building a habitat somewhat artificially to help protect the shoreline. As well, someone may wish to secure the local vegetation in a range that will likewise give an environment to diversion and natural life in the region. However, one would say these processes are temporary as a result the movement of sediment is always changing. All the same, it is a phenomenal approach to attempt to secure the shoreline.

The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the creation and maintenance of habitats. Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. The finer-grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle

One of the main causes for Desertification is something named Erosion. The definition for Erosion is when the

The coast is the buffer between terrestrial land and the marine, it is the boundary of where land meets water which is known as the coastline. Tides, waves and currents are what help form coastlines. However, when waves meet or crash on the shore, they erode the land, leaving behind tiny parts of the sea such as shells, seaweed and marine life. Although, over the past 30 years central beaches are continually eroding because sand is pushed along the coast by waves. (BAC Australia, n.d) Coastlines are badly affected by erosion and The Coast Protection Board is urgently needed to protect and manage Adelaide’s beaches. Without them managing the beaches, several of Adelaide’s southern metropolitan beaches will be left with very little sand on them.

This chemical based erosion occurs only with certain types of rock such as chalk or limestone, which are high in calcite. The acidity of the seawater causes a chemical reaction in the mineral, eating away at it. Another form of erosion is abrasion. This occurs when the sediment suspended in the water is thrown against the shore by waves. The sediments grind against the land, weakening the structural integrity of the coastline. Attrition is also a form of erosion. It’s the continued wave action hurls stones and other material at the land, which smooths and breaks up the rocks on the coast, dislodging them from one another. These in turn collide with other rocks on the

Coastal erosion is a major problem in Sri Lanka. A fairly small island by itself, coastal erosion will lead to even less land for Sri Lanka. The coastal districts also contribute to more than 40% of Sri Lanka’s GDP. As such, if severe coastal erosion occurs, it would negatively affect Sri Lanka’s economy.

The coastline are undergoing changes through time which can be attributed to natural processes while others are attributed to human activities though most of them are due to both factors. This calls for human intervention which involves attempts to stabilize or what can be termed as hardening of the shoreline. This approach taken will lead to various long-lasting consequences on the natural system both locally as well as the area surrounding; these effects can be both positive and negative. This paper looks at various techniques and efforts that have been used in the stabilization of shores throughout the world and further establish if they are temporary or permanent. Finally it will look at how development of coastal areas has played a role to shoreline erosion.
