An Integrated Multi-Factor Coupling Approach for Marine Dynamic Disaster Assessment in China’s Coastal Waters

Marine dynamic disasters, such as storm surges and huge waves, can cause large economic human losses. The assessment of marine disasters is, thus, important, but improvements to its reliability are needed. current study improved integrated the from perspective multi-factor coupling. Using a weighted index system, disaster indicator system suitable for China’s coastal waters was established, method calculating weight indicators proposed rapid assessment. To reduce deviation in waters, coupling algorithm proposed. This obtained amplitude variations wave orbital motion horizontal vertical directions, which used evaluate influence background terrain slope on ocean waves. Landsat 8 remote sensing images were carry out an object-oriented extraction raft cage aquaculture areas waters. density then main basis vulnerability Finally, whole verified during typical surge process around Shandong Peninsula China. coupled also added increased risk value by average 12% High Sea States case study.
