The Current Levels of Shoreline Hardening and Explain the Growth of Coastal Populations

Princy Bandla

Shoreline hardening causes beach loss globally and it will accelerate with sea level rise (SLR), causing more sea loss if management practices are not changed. To develop the beach conservation efforts, the present and future shoreline hardening phenomenon on sandy beaches need deeper analysis. A shoreline change model driven by incremental SLR is used to simulate future changes in the position of an administrative hazard zone, as a proxy for risk of hardening at all sandy beaches on the island of hardening can be triggered when evidence of erosion is within 6.1 m of certain structures, allowing an applicant to request emergency protection. The results show an increase in shoreline vulnerability to the hardening with SLR governed by the backshore land use patterns.
