Beach renourishment

With sea levels rising, renourishment of beaches has become a billion dollar per year industry.  What is this process and when is it a good investment?

Beach erosion is replaced by dredging sand typically from offshore to renourish the beach.  The process is costly several million dollars per mile on the typical shorefront.  With sea level rising at 3.2 mm/year this puts more and more pressure on beaches; which means more beaches need renourishing and the new sand may not endure.  Thirty years ago there was one renourished beach, Miami Beach.  Today on the east coast there are not many major beaches that have not been renourished.  A list with costs is provided by Western Carolina University. Below are some visual examples or renourished beaches.  The key to determining if it is a good investment is:

  • What is the duration of the repaired beach?
  • Does it prevent damage?
  • Value of real estate it protects?

  1. The process of beach renourishment entails using sediment such as sand to replace and restore beach territory that has been damaged by erosion. It is a good investment when it threatens the survival of development, land, animals, and humans that settle along shorelines. For example, Miami Beach in Florida has gone through numerous renourishment episodes because there is extensive development near the coast. Through erosion and sea-level rise, many people’s lives would be at risk and the properties that surround the ocean would be completely destroyed without renourishment. Animals and plants around the area would also be in great danger if these renourishment episodes are not performed as erosion and sea-level rise increases.

  2. Beach renourishment is a process by which dredging sand, primarily from offshore, is used to fill in lost sand caused by erosion after a major storm hits the beach. Investing the money needed to properly renourish a beach is a good idea if that beach will not be able to withstand potential future storm damage without the help of the renourishment. The renourishment process can certainly be costly; however, if done correctly, the positive impact on the beach will tremendously outweigh the cost. For example, Long Island Beach suffered significant damage after it was hit by Hurricane Sandy. Workers had no other choice but to use funding to renourish the beach because without it, Long Island Beach would be completely destroyed if and when another storm hit.

  3. Renourishment of beaches is a process in which the beach is restored with sand as it was lost through drift or erosion. Beach renourishment moves the point of erosion farther seaward which gives more time before erosion destroys the beach. To renourish a beach it can take anywhere from three to six months. Beach renourishment is good for beaches that have a high real estate. It creates greater protection from the storm. It also widens the beach making the beach a more ideal place for tourists to go to. For example, Myrtle Beach has gone through the renourishment process, as it is a large travel destination. Beach renourishment allows the tourists of Myrtle Beach to keep coming back and enjoy their vacation. As tourists bring money to Myrtle Beach it makes it worth it for renourishment of Myrtle Beach to be done.

  4. Beach Renourishment is a process that sand lost through longshore drift or erosion is replaced from other sources. It is a great investment for a popular and heavily popular beach. This is a very expensive project but should be done every so often in order to have a safe and healthy beach.

  5. Sand from offshore replaces beach erosion in order to renourish the beach. Beach renourishment is a good investment depending on the duration of the repaired beach, whether the renourishment prevents damage, and the value of the real estate it protects. Because renourishment is so expensive and has to be done every couple of years, many think that beach renourishment is not worth it. However, beaches that are popular tourist destinations often do have their beaches renourished in order to keep tourists coming back. For example, beaches in Cancun, Mexico were renourished after damage caused by Hurricane Wilma.

  6. Without beach renourishment, there wouldn’t be a “buffer” between the harsh waves and good real-estate on say islands, popular beaches, and peninsulas. Damage to the beach could lead to inland erosion and potential flooding in places that are below sea-level. Renourishment prevents any further damage due to high-tide, tropical storms (hurricanes, spouts, coastal storms), and sea-level rise thanks to glacial melting.

  7. Beach Renourishment is dredging sand typically from offshore to renourish the beach. The process is costly several million dollars per mile on the typical shorefront. Beach nourishment has the potential to promote recreation and tourism through beach widening. This may serve to enhance pre-existing tourism or may serve to attract tourists to the area, encouraging development. The renourishment process is very costly, so it is important to be done right to benefit from the expensive cost.

  8. Beach renourishment is when sand is brought in from offshore to help rebuild the beach. They often use other structures underneath the sand to help keep it all in place, but eventually erosion still causes it to wash away. because of this it is only a temporary fix, but is definitely worth it in communities that rely heavily upon the local beaches to bring business in and make a living. an example of a beach that has been renourished is Myrtle Beach, SC who started their project in July 2017.

  9. The process of beach renourishment is to prevent any damage to the beach or the residences that lay beside it. By refilling the areas that were damaged by storms, erosion, and other situations like those, you are making the beach wider and stronger. In the end it is an expensive but good investment because you are preventing anymore future damage caused by storms.

  10. The process of renourishment is when the sand lost through earth’s factors of erosion and others is replaced through other sources. The idea of replacing the sand allows a temporary fix to the beach to prevent harmful and even deadly instances to occur to the areas surrounding the beach and coastal areas. Renourishment is a good investment when they know how frequently the beach needs to be fixed and if it is necessary, it is also used to prevent damage and value to real estate surrounding if there are many homes. This need for renourishment is becoming more common due to global warming and the ice sheets and glaciers melting.

  11. The process of beach renourishment begins with a loss of sand due to erosion or longshore drift and the only way to recover the beach is by adding more sand from other sources. The renourishment can result in a wider beach thus helping in reducing storm damage and protecting upland structures from natural disasters such as tsunamis or storm surges. I believe it is a good investment to renourish some beaches especially beaches that have high tourist activity. For example, Miami is a city that draws millions of people into the city especially due to the city being located directly on a beautiful beach. Since the beach is the driving factor for most of the income being produced in Miami, spending a lot of money to have the beach renourished and remaining to look beautiful even if a storm hits, such as Maria, then the city will not have to worry about tourists not considering Miami as the highly respected vacation spot it is today.

  12. Without Beach renourishment, we wouldn’t have a lot of the luxurious beaches that we have today. I honestly never knew that beach renourishment was a thing, however when you really think about the environment around us, it is disappearing right underneath our feet. It’s kind of scary to know that we purposely need to fix the land around us, even though we were the ones that kind of killed it first.

  14. Beach renourishment is when a dredge transits offshore to a borrow area (a place on the seafloor were there’s suitable sand that we can pump onto a beach). The dredge sucks up that sand, holds it in a hopper (a container in the dredge), comes back toward the shore and pumps it onto the beach through submerged pipe and through baskets. And then bull dozers and land equipment maneuver the sand and push it into a dune and a berm that’s protected and helps reduce storm damages.

    A stabilized beach requires a constant source of supply otherwise erosion impacts will quickly relocate sand elsewhere. If renourishment is done, constant care must be done to the beach dry width. Renourishment is a good investment when it prevents places like Long Beach Island to be signicantly damaged when tropical storms or superstorms hit the coast. A protective berm and dune system can save the island if done properly.

  18. Beach renourishment is the process by which sediment, usually sand, lost through erosion or drift is replaced from other sources. Beach renourishment is primarily done by dredging. Dredging is when sand is digged, or pumped, from the bottom of the ocean to the area of renourishment. This is where the Army Corps of Engineers and other experts of machinery push the sand to fill the areas that have been eroded and smooth the top layer off. This is a very time-consuming process but ultimately can prevent storms or the increases of sea level in the future to wash away coastlines. Although it is very expensive, beach renourishment is a necessity in order to have beaches keep attracting tourists. Beach renourishment is a good investment to some of the most highly populated beaches and the ones that are prone to the most erosion. An example of a beach/port that has been nourished four times is Port Canaveral Harbor Sand Bypass. It is a good investment to keep nourishing this area because this is where some of the biggest cruise lines go to be boarded.

  19. Beach renourishment is when beach erosion or LST decreases the amount of sand on a beach and construction crews go in and supply the beach with new sand in which they brought in from either the ocean, or they got it from somewhere else. It is a good investment if you are looking at it from a real estate and attraction point of view because without it no money will be made on these popular beaches. However, overall it is not a good idea. It is a very costly expense and not only does it have to happen often, it isn’t technically healthy for the beach.

  20. I believe that beach renourishment is not always the best investment but i understand why we need to do it. I understand that without it there would be consequences such as flooding and causing lands to be below sea level. Yet, in a realistic approach we are only stalling the inevitable. We spend billions on this renourishment only to have the water flow over the land eventually. While it can prevent damage in the future, I only worry if it’s truly worth it. For example, Pawley Beach has had done renourishment three times in three years and the pictures do not show much of a difference on google earth. Real estate is right on the beach and is below sea level so there won’t be too much renourishment can really do if it has already failed three times before.

  24. Renourishment allows us to effectively control a variety of variables regarding a beach. The shore serves as a buffer between the ocean and any real estate that may lie along the shore. This process also allows us to combat rising sea levels in an effort to protect property. Sandbridge Beach, VA is a great example of how effective renourishment can be. This beach is known for its extensive renourishments projects that seem to improve the beach overall each time. The beach evolved over time from a seawall to a full beach with the slow formation of dunes. Efforts like these will become more common as sea level continues to rise.

  26. The reason we need to renourish our beaches is to keep the shore from coming inland. If it wasn’t for renourishment’s people would lose their homes, there would also be a lot of roads, crops and beaches lost. It may be an expensive project to conduct but without it we could lose a lot. If our coast were to be hit by a big storm and we didn’t renourish, we would lose the beach a long with a lot more homes and businesses.

  27. Beach renourishment occurs when the sand on the beach decreases from things like erosion and sand gets added on with other materials because without it the beach could become too damaged and also it could cause flooding. Taking care of a beach is very expensive but it needs to be done so it can reduce things like flooding.

  28. Renourishment of beaches is necessary due to drifting and/or erosion over a certain period of time. Sand, usually from offshore, is brought in to manually restore the beach’s structure. In addition, this also helps with erosion in the future, as the point of erosion is placed further out from the beach, so erosion takes a longer period of time to potentially affect the beach. Although renourishment is a rather expensive project, it is worth the investment on beaches that particularly have expensive real estate. Any beach that has a high tourist population should invest in this process when necessary to ensure and maintain satisfaction from its visitors and residents.
