Abstract Wave setup and swash statistics were calculated from 154 runup time series measured on a moderately
steep beach under incident waves varying from 0.4 to 4.0 m significant wave height. When scaled by the
incident wave height, setup, swash height, and total runup (the sum of setup and half the swash height)
were found to vary linearly with the surf zone similarity parameter ξ₀ = β(H₀/L₀)¯½ The foreshore
slope appeared the appropriate value for the calculation of ξ₀, although the setup data showed some
influence of an offshore bar at low tide. For low Irribaren numbers the swash height in the incident
frequency band becomes saturated, while for high Irribaren numbers, no such signs of saturations were
seen. Thus the infragravity band appears to become dominant in the swash below some value of ξ₀. For
these data, that value is approximately 1.75, although there is considerable scatter associated with that
estimate.
