|a This paper investigates changes in shoreline evolution caused by changes
in wave climate. In particular, a number of nearshore wave climate scenarios corresponding
to a ‘present’ (1961–1990) and a future time-slice (2071–2100) are used to
drive a beach evolution model to determine monthly and seasonal statistics. To limit
the number of variables, an idealised shoreline segment is adopted. The nearshore
wave climate scenarios are generated from wind climate scenarios through point
wave hindcast and inshore transformation. The original wind forcing comes from
regional climate change model experiments of different resolutions and/or driving
global climate models, representing different greenhouse-gas emission scenarios. It
corresponds to a location offshore the south central coast of England. Hypothesis
tests are applied to map the degree of evidence of future change in wave and shoreline
statistics relative to the present. Differential statistics resulting from different
global climate models and future emission scenarios are also investigated. Further,
simple, fast, and straightforward methods that are capable of accommodating a great
number of climate change scenarios with limited data reduction requirements are
proposed to tackle the problem under consideration. The results of this study show
that there are statistically significant changes in nearshore wave climate conditions
and beach alignment between current and future climate scenarios. Changes aremost
notable during late summer for the medium-high future emission scenario and late
winter for the medium-low. Despite frequent disagreement between global climate
change models on the statistical significance of a change, all experiments agreed
in future seasonal trends. Finally, a point of importance for coastal management, material shoreline changes are generally linked to significant changes in future wave
direction rather than wave height. |
