In this Earth, about 60% of it’s population lives along coasts. But, erosion may occur along the coast and causes the land to retreat inland and affect the building along the coast. Thus, there is a need to protect them. Coastal protection measures is divided into two groups, the hard engineering and the soft engineering.
Hard engineering means the building of structures that could prevent erosion, such as Seawalls, Breakwaters, Groynes, and Gabions. In other hand, the soft engineering is a cheaper option than hard engineering and it applies knowledge of natural processes to protect the coast. Examples are Stablising coastal dunes, Planting mangroves, Beach nourishment, and by Encouraging the growth of coral reefs.
