Figure 14. Average wave height for no pit, pit 1, and pit 2.
Figure 14. Weighted average significant wave height for the (A) baseline, no pit bathymetry, (B) bathymetry including borrow pit 1 (change from baseline shown in D), and (C) bathymetry including borrow pit 2 (change from baseline shown in E). Borrow pits are outlined in white. The average is created from the output of individual scenarios, weighted by their percentage occurrence over the time period December 1995 through December 2013 (fig. 2). The pits create a shadowing effect originating from the corners.
