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