Three tests consisting of fifty 400-s runs were conducted in a small-scale wave flume to examine the effect of net cross-shore sand transport on an equilibrium profile. The profile changes among the tests were relatively small. An analytical model for an equilibrium profile with net cross-shore sand transport is developed. The model predicts the horizontal shift of the equilibrium profile under net cross-shore sand transport. The model calibrated using the tests are used to estimate the seaward shift of shoreline on periodically-nourished beaches of prototype scale. The estimated shift is minimal but will need to be verified using field data
