Figure 22, example mobility map
Figure 22. Mobility ratio (table 2, metric 5) in the northern Gulf of Mexico alongshore Alabama and Florida for a midlevel threshold of 2.5-centimeter surface residual balls (SRBs; table 1) for scenarios A, H3_D6 and B, H4_D6 (fig. 2). Areas with a mobility ratio of 1 (in pink) indicate where the mobility threshold was exceeded. Whereas the mobility threshold is exceeded only in small sections in very shallow water in A, the large wave heights result in mobility along the coast as well as over shallow bar and ebb tidal delta features in B.
