Abstract

Studies of coastal erosion and coastal management can be put on a firm physical basis only after methods have been developed for closely estimating the energy expended in actual unidirectional net littoral transport of sediment. Such measures have now been obtained for six coastal drift cells. The results, for a 68-year period, vary from a minimum of 0.6 x 104 ergs (very low energy) to a maximum of 340 x 104 ergs (moderately high energy) per cell.
