The influence of coral reefs and climate change on wave-driven flooding of tropical coastlines

摘要: A numerical model, XBeach, calibrated and validated on field data collected at Roi-Namur Island Kwajalein Atoll in the Republic of Marshall Islands, was used to examine effects different coral reef characteristics potential coastal hazards caused by wave-driven flooding how these may be altered projected climate change. The results presented herein suggest that coasts fronted relatively narrow reefs with steep fore slopes (~1:10 steeper) deeper, smoother flats are expected experience highest wave runup. Wave runup increases for higher water levels (sea level rise), waves, lower bed roughness (coral degradation), which all Rising sea change will therefore have a significant negative impact ability mitigate future.
