[ Abstract ]Significant buffering of the impact of tsunamis by coral
reefs is suggested by limited observations and some
anecdotal reports, particularly following the 2004 Indian
Ocean tsunami. Here we simulate tsunami run-up on
idealized topographies in one and two dimensions using a
nonlinear shallow water model and show that a sufficiently
wide barrier reef within a meter or two of the surface
reduces run-up on land on the order of 50%. We studied
topographies representative of volcanic islands (islands with
no continental shelf) but our conclusions may pertain to
other topographies. Effectiveness depends on the amplitude
and wavelength of the incident tsunami, as well as the
geometry and health of the reef and the offshore distance of
the reef. Reducing the threat to reefs from anthropogenic
nutrients, sedimentation, fishing practices, channelbuilding,
and global warming would help to protect some
islands against tsunamis.
