Plots are produced using tide data from the NOAA La Jolla, CA tide station and wave data from the CDIP regional wave model. The runup, or vertical level reached by 2% of waves (R2%) is calculated using the following estimate from Stockdon et al (2006):
R2% = 0.043 (H0L0)1/2
where H0 is the incident wave significant height, T is the wave period, and L0 = (g/2pi)T2 is the deep water wavelength. In this instance, Tmean is used instead of Tpeak used in Stockdon, to eliminate jumps in R2% in bimodal waves with approximately equal sea and swell energy. The maximum water level is defined as the tide + R2%. H0 and L0 are calculated using parameters from the CDIP regional wave model in 10m depth and averaged over a 500m alongshore section. Predicted tides from the NOAA station are adjusted by adding in the difference between the last monthly mean MSL value and the MSL datum (1983-2001) for the La Jolla, CA tide station.
