The cross-shore variation of the local reflection coefficient R is examined under the
assumptions of normally incident wind waves on beaches with alongshore uniform
bathymetry. The existing three-gauge method is modified to estimate R for the sloping
bottom. A new method is developed to estimate the incident and reflected root-mean-square
(RMS) wave heights from the measured RMS wave height and wave setup. These methods
are used to analyze six runs from the large-scale SUPERTANK data set. The estimated …
