The CB4 coastal belt extends approximately 3095 m and includes thin red lines that separate the individual domain segments. This coastal belt is divided into five BCCS (Biophysical Cross-shore Classification System) domains, the largest of which (Namada) is characterized by the cross-shore catenary sequence: 2Cr_fr,paF_saBe_caDv_coM_fo,sr. The adjacent coastal belt (CB5) is delineated by a thicker red line. All codifications for CB4 can be keyed using Table 1 and the summary data for this coastal belt corresponds directly with Table 4.
