Abstract
Analogue wave records and associated wave spectra from field measurements of wave transformation across two nearshore bar systems in Georgian Bay, Ontario, show considerable growth of energy in the higher harmonics; in addition, there appears to be a regular spatial pattern of energy transfer between the peak frequency and the first higher harmonics with a length dimension equal to the spacing between the bars. Model predictions of bar number and spacing, starting with an initially planar slope, correlate well with the field measurements, for the two sets of wave conditions and mean slopes; in addition the model is able to predict profile changes reflecting seasonal changes in wave climate.; in addition the model is able to predict profile changes reflecting seasonal changes in wave climate.
