ACCRETION - EROSION IN THE BEACHES OF THE CANARY ISLANDS (SPAIN)

Abstract

In the beaches under study on the island of Grand Canary, we are identifying and measuring the intertidal annual cyclic processes of accretion and erosion, starting from the topographical movements of the strand. These processes: a) We are analyzing and interpreting these in the framework of the physical and geographical interdependences, and as responses to the more internal evolutions of the morphodynamics, in the sedimentary environments in question, b) and permitting the definition and calculation of some indices of sedimentary gains and losses, of interest to coastal planning and management.
