Once more on longshore drift at open oceanic coasts

Abstract

Using space images data on West Afr.ica coast and referring to A. Guilcher article on Angola, O. K. Leontyev and M. V. Belodedenko came to conclusion opposite to this of P. A. Kaplin a. o., the latter say that usually there is no longshore drift of debris at open oceanic coasts, and large built-up coastal forms are not connected with the drift. Analyzing the same data the authors of the given paper argue that West African coast dynamics can be explained not by longshore drift (as O. K. Leontyev and Belodedenko assumed) but by transversal movement of debris (from sea to land). The large built-up coastal forms may have but external resemblance to the forms, created by longshore drift. In fact, they result from continuous debris supply from sea floor towards the coast.
