Beach Morphodynamics and Profile Sequence for a Headland Bay Coast

This paper presents a sequence of beach profile for a headlands and bay coast. Shape analyses of the embayed beach, identification of the predominant wave direction, beach and nearshore profiles, sedimentology characteristics, hydrodynamic conditions at the beaches, morphodynamics and morphometric data for 17 beaches on central-north coast of Santa Catarina, Brazil, were obtained. Beaches are classified in three main groups: (1) exposed; (2) semi-exposed; and (3) sheltered. The exposed beaches had an indentation ratio smaller than 0.39 and the dominant south waves are approximately parallel to the coast (angle smaller than$40 \textdegree$). The beaches can be divided into three mainly groups, (a) Reflective beaches have coarse sand (0.59mm-0.94mm) and steeper nearshore slope (1:40) associated with a very narrow coastal plain (
