Quick look: Stockdon, Hilary F.; Holman, Rob A. Video-based observations of wave runup, setup, and swash from 10 dynamically diverse field experiments are presented. These data were used to develop widely applicable empirical parameterizations for wave setup, incident band swash height, infragravity band swash height, and the 2-percent exceedance level for wave runup.
