The 176.2-km long coastal belt throughout the Rocha Department extends from the southern border of Brazil southward and includes the Rocha Super Domain with an archetype codification of Beach-Dune-Wetland-Lagoon (Be-Du-W-L). Red lines separate the individual domain segments that were classified throughout the department. This coastal belt is divided into 13 Biophysical Cross-shore Classification System (BCCS) domains, the largest of which is a littoral cell (Domain 2-9) that is characterized by the cross-shore catenary sequence Be_siR_seDu_bo,foW_mr,sl. The La Paloma Divergence Zone separates littoral cells in Domains 2-9 and 2-11. Rock promontory outcroppings are shown with light-orange caret symbols along the coast. All codifications can be keyed using Table 1, and morphometric analysis of the Rocha Department corresponds directly with Table 2.
