Aspects of Coastal Morphology

Abstract

Much of the early literature on coastal morphology was concerned with classification of types of coast and unfortunately this interest continues. It is contended that familiarity with coasts on a broad basis and understanding of shore processes will not be sufficient to justify taxonomic generalizations for many years. Quaternary landforms of erosional origin must be related to sea stands much lower than today's, but Recent depositional forms originated mainly during the last few thousand years. Maximum development of estuaries—features rare during most of geologic history—occurred during Quaternary high stands of the seas, as at present. Most of these are subject to rapid extinction by alluviation. Delta stream patterns differ from those of flood plains in origin and appearance. Selected topics in beach morphology are discussed. The volume of sand on beaches is being rapidly diminished.
