Figure 1 1 . Edge wave k-f spectra solutions showing a steepening of modal 

 dispersion lines from plane beach solution. Mode 0, 1, and 2 

 numerical (measured depth profile, asterisks) and analytical 

 (planar depth profile, solid) dispersion solutions are plotted (from 

 Oltman-Shay and Howd 1993)
