A Note on Shore Protection and Beach Utilization on Sand Cays in Maldives

Abstract

Aerial photographs of coral islands in Maldives were taken to investigate the streak pattern developing on the shallow coral reef surrounding small islands. These streak patterns correspond well with the streamlines of the nearshore currents induced by wave breaking. The direction of the littoral transport was determined from these streak patterns. Beach erosion caused by the effect of the construction of impermeable jetties was investigated and plan ning method to prevent beach erosion was discussed.
