DELILAH Runup Spectra and 



Beach Profiles 



The following spectra (Figure Al) were computed from video runup 

 time series measurements made on FRF profile line 995m. Most runs were of 

 120-min duration and have spectral estimates have 93 degrees of freedom (dof). 

 Shorter duration runs can be identified with fewer dof, the shortest was 90 

 minutes with 65 dof. Spectral analysis was done using segment (ensemble) and 

 frequency band averaging (Bendat and Piersol 1971). 1 The spectra have a 

 resolution of approximately 0.005 Hz. Statistics shown for infragravity (0.001- 

 0.04 Hz), swell (0.05-0.15 Hz), and sea (0.15-0.32 Hz) frequency bands. 



Beach profiles (solid thin line) from the DELILAH experiment are show 

 in Figure A2. The range of swash excursion is indicated with a thick line drawn 

 on the profile. The dotted horizontal lines indicate the NGVD vertical datum 

 and mean tide level recorded at 8-m depth (inverted triangle). An estimate of 

 setup can be made from the elevation difference between the average runup 

 (circle) and the mean tide level. The mean runup cross-shore position (X) and 

 elevation (Z) are listed in the tables. The Iribarren number (£,) beach slope, and 

 FLj,, (measured at 8-m depth) are also listed for each run.
