Seawalls are traditional coastal protection structures, while artificial reefs, beach nourishment, and groynes are considered innovative technologies.

Artificial reefs serve multiple purposes, including reducing wave energy, providing habitat for marine life, and improving water quality.

Sand is the primary material used in beach nourishment projects, as it is naturally found on beaches and can be easily transported and placed.

Groynes are structures built perpendicular to the shoreline to trap sand and prevent erosion.

Innovative technologies for coastal erosion management offer several advantages, including being more environmentally friendly, cost-effective, and effective than traditional methods.

The main challenge associated with the use of innovative technologies for coastal erosion management is the lack of scientific evidence to support their effectiveness.

Mangrove restoration is an example of a nature-based solution for coastal erosion management, as it involves restoring mangrove forests, which provide natural protection against erosion.

The primary goal of coastal erosion management is to protect coastal property and infrastructure, preserve coastal ecosystems, and improve water quality.

Coastal erosion is caused by a combination of factors, including sea level rise, storms, and human activities such as coastal development and dredging.

Seawalls are an example of a hard engineering structure for coastal erosion management, as they are built to physically protect the shoreline from erosion.

The main advantage of using soft engineering techniques for coastal erosion management is that they are more environmentally friendly than hard engineering structures.

Dune restoration is an example of a soft engineering technique for coastal erosion management, as it involves restoring natural dunes, which provide protection against erosion.

Vegetation plays a crucial role in coastal erosion management by stabilizing the shoreline, reducing wave energy, and providing habitat for marine life.

Zoning regulations are an example of a non-structural measure for coastal erosion management, as they restrict development in areas that are vulnerable to erosion.

Public participation is important in coastal erosion management because it helps to ensure that the needs of the community are met, increase awareness of coastal erosion issues, and build support for coastal erosion management projects.
