Coastal erosion is a huge problem. You might be asking yourself why you should be worried about the condition of some beach, but in truth it does have an impact on the economy that you might not have even though of. Did you know that people live along coastlines mostly for the beaches? With the threat of coastal erosion, many people may end up moving elsewhere, which will cause a downfall of that particular area. That's why it is so important to make sure coastal erosion is stopped in its tracks.
Breakers can be placed in the water at certain points to slow down the waves. Naturally this isn't going to stop the erosion, but it will slow it down. The one problem with this method is that you will absolutely need to obtain a permit from the state before you begin. If you do not, then you may end up with some serious legal trouble on your hands.
A living shoreline is always going to help. Make sure you plant plenty of seaweed and create an environment that sea creatures will be attracted to. More life means less chance of erosion, which is exactly what you're going for.
Beach nourishment is a great option for stopping erosion. The best thing you can do is transplant sand from other areas. In some cases you will be able to purchase sand in bulk, which is a great way to keep your beach looking nice and healthy.
Wind breaks are always a good idea. These can be small fences that you set back from the beach a little bit. More than likely you've seen these somewhere before, probably at one of the more popular beaches.
Barrier walls can be placed at the beach if you're not entirely worried about aesthetics. This will stop the waves from hitting the sand and eroding it over time. It may not look great, but it will do the job, especially if you have a house on the beach that you need to protect.
