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. Details regarding the experiments, data analysis, and empirical parameterizations can be found in Stockdon and others (2006).
Runup, swash, and setup observations were collected using video techniques developed at the Coastal Imaging Lab at Oregon State University and previously tested against in-situ runup instruments (Holman and Guza, 1984; Holland and others, 1995). Cross-shore transects of pixel intensity were sampled at 1 or 2 hertz over 17- to 120-minute record lengths, depending on the site. Longer time series were broken into 17-minute records in order to minimize the effects of changing tide levels on the location of wave breaking and on the location wave swash on the foreshore.
The leading edge of swash (runup/rundown) was digitized on timestacks of pixel intensity and then converted to time series of water-level elevation. Measured tidal curves were removed from each time series, making elevation statistics relative to the still-water level. Setup and swash statistics were calculated from the 17-minute continuous water-level record. The time average of the record defined the wave setup, <η>. After removing <η>, significant swash height was calculated from the spectra. The incident and infragravity components of swash were calculated using a frequency cutoff of 0.05 hertz. Runup statistics were defined as the elevation of individual water-level maxima above the still-water level, merging contributions from both setup and swash. The 2-percent exceedance value for runup, R2, was calculated from the cumulative probability density function of runup elevations.
To allow for inter-comparisons of deep-water equivalent wave heights between different field sites where wave conditions were measured in varying water depths, an effective deep-water significant wave height, H0, was calculated for each water-level time series. Significant wave height from local buoys and instrument arrays, Hs, was reverse-shoaled to deep water using linear wave theory, assuming a shore-normal approach. The peak wave period, To, corresponding to Hs, was also extracted at the time of each water-level record.
The foreshore beach slope, βƒ, was measured over the portion of the profile where runup was observed. It was defined as the average slope over a region ±2σ around <η>, where σ is the standard deviation of the continuous water-level record.

Data from 10 field experiments, representing a wide range of morphologic and hydrodynamic conditions, were analyzed for this study:
The data are available as text files.
Each experiment-specific file contains: date (yymmdd), time (GMT), 2-percent exceedance value for runup (meters), setup (meters), total swash excursion (meters), incident swash (meters), infragravity swash (meters), significant deep-water wave height (meters), peak wave period (seconds), and foreshore beach slope (radians). A description of the variables is given in readme.pdf (282-KB PDF). Download the free Adobe Reader for viewing PDF files.
