selected here representing a wide range of wave and beach conditions (Cases
1, 3, 4, and 7). Kraus and Larson (1991) summarized the experimental
arrangement and conditions, measured wave height, mean water level, and
longshore current used in the comparisons. For reference, the wave
conditions in the horizontal portion of the basin during the experimental cases
studied are listed in Table 4. In summary, Case 1 encompassed large incident
wave angles and smooth bottom; Case 3, large wave heights and smooth
bottom; Case 4, an average wave condition and smooth bottom; and Case 7,
an average wave condition and rough bottom.

Because Visser's experiments were run with monochromatic waves, not
involving the additional complexity of random waves breaking at different
locations across the profile, it is an excellent data set to evaluate model
performance with respect to features such as the wave-current interaction and
the roller model. Kraus and Larson (1991) investigated both a linear and
