Different designs of man-made tsunami barriers include building reefs and forests to above-ground and submerged seawalls. [9] Starting just weeks after the disaster, in January 2005, India began planting Casuarina and coconut saplings on its coast as a natural barrier against future disasters like the 2004 Indian Ocean earthquake.

A natural barrier is a physical feature that protects or hinders travel through or over. Mountains , swamps , deserts and ice fields are among the clearest examples of natural barriers.
Lagoons are areas that are separated from larger water by natural barriers such as coral reefs or sandbars. There are two types of lagoons, coastal and oceanic/atoll lagoons. [23] A coastal lagoon is, as the definition above, simply a body of water that is separated from the ocean by a barrier.

Natural harbours are formed by such barriers as headlands or reefs. Artificial harbours can be created with the help of breakwaters. Artificial harbours can be created with the help of breakwaters. Mobile harbours, such as the D-Day Mulberry harbours , were floated into position and acted as breakwaters.
An aquatic sill (or an oceanic sill) is a sea floor barrier of relatively shallow depth (tens to hundreds of meters) that restricts water movement between benthic zones of an oceanic basin or lake bottom. [1] There are roughly 400 sills in the Earth's oceans, covering 0.01% of the seafloor. [2]
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. [1] Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone.
It reduces erosion on the other, i.e. downdrift, side by reducing the speed and power of the waves striking the shore. It is a physical barrier to stop sediment transport in the direction of longshore drift (also called longshore transport). If a groyne is correctly designed, then the amount of material it can hold will be limited, and excess ...
