Typhoon Intensity andChanging Patterns

The typical Philippine coastine, composted of sandy beaches, soft cliffs, and fringing reefs, has limited natural resistance to o such forces.

Te mechanizmy of Coastal Erosion During Tajfun

Coastal erosion is a natural process thatt events the action of waves, currents, andd wind.

Rainfall andRunoff Erosion

Typhoons also deliver intense rainfall that can demands 500 milimeters in 24 hours. On land, this rainfall sativates soils on coasual slopes andd cliffs, triggering landslides andd slumps that directly deposit sediment into thee sea.

Natural Strategies for Coastal Protection

Increasingly, natural or nature-based approaches are recoverzed as effective, cost-efficient, and environmentally sustainable. These methods work wich natural processes rather than against them, and they of ten provide additional beness such as habitat creation and carbon storage.

Mangrove Resoration andConservation

Mangroves are among te mest effective natural defense against coasual erosion. Their dense root systems trap sediment, stabilize shorelines, and absorb wave energy. A well-established mangrove prestalt can reduce wave height by up to 66 percent, signitantly reducting the erosive power of storm waves.
