![]() Most of these structures last between 30 and 50 years. Well, breakwaters are breaking (pun intended) that belief. They are used for protecting the coastline from storm surges, swells, and tides that could cause erosion to the beach they’re also used for calming the water for vessels.Įverything submerged in water doesn’t seem to last long, right? Offshore breakwaters are detached from the land and built parallel to the coastline. They’re used for keeping port waters calm.Īt a harbor, it’s common to see onshore breakwaters create a squared space–with an opening–for boats to safely dock. Onshore breakwaters, as the name suggests, are attached to the shore. The structures are known for being very secure, even in rough conditions, and they can be used in deep seas. Monolithic (also referred to as vertical breakwaters) have a vertical wall built from a rubble foundation. These filter layers are made up of piles of other rocks or concrete structures, which, in a perfect world, keep the core part of the structure intact. Rubble-mound breakwaters are designed with a mound-shaped core (made of stone, concrete, or rocks) that is protected by filter layers. So, let’s take a dive into what each of these descriptions means to give you a better understanding. What Are the Types of Breakwaters?īreakwaters are generally separated into two categories: Rubble-Mound Breakwaters and Monolithic Breakwaters.īut within those categories, they can also be separated by being onshore or offshore structures. So, now that you know the answer to the question of what is a breakwater, keep an eye out for them the next time you’re near a harbor or dockyard! 2. ![]() They have allowed several towns to develop prosperous dockyards and harbors. Thanks to these structures, the water behind them (closest to the coast) is much calmer. However, modern breakwaters, as we know them today, hit the scene in the 18 th century, making them a relatively new invention. Researchers have found evidence of the Roman Empire using them along the coasts of Italy around the first century. Sometimes they are detached structures, and sometimes they are connected to the land.īreakwaters have been used for thousands of years. The structures are typically made of stone and rocks (wood has also been used), and they’re usually placed in shallow water to make the building process as easy as possible. What is a Breakwater?Ī breakwater is a barrier placed off the coastline to provide protection against swells, storms, currents, and tides. Put on your sailor hat because we’re heading out to sea! 1. So, we’re not only going to answer the question of what is a breakwater, but we’re also going to check out everything you could ever need to know about them! They’re fascinating structures that many people don’t stop to appreciate or dive into. If you’ve been to a harbor, you’ve like seen a breakwater before.īut no breakwater is the same, and they’re scattered along coasts around the world, taking on various designs. ![]() One of these successful solutions is breakwaters.īreakwaters are large walls constructed off the coastline to reduce the power of incoming swells. Instead, engineers have devised solutions to protect coastlines from violent swells, giving way to bustling port towns and important harbors. The ocean is a mighty force that’s not to be taken lightly, which is why we have breakwaters.Įvery few years, we see just how destructive a ferocious swell can be, flooding coastal towns and tearing through harbors.īut humans are reluctant to back down from the formidable, salty opponent. ![]()
