RELATIONSHIPS BETWEEN SHORELINE CHANGE RATE, WAVE ENERGY FLUX AND LONGSHORE CURRENT VELOCITY IN LONG-TERM SHORELINE CHANGE

Abstract

The characteristics of shoreline change, offshore wave energy flux and longshore current velocity were investigated with a 15-year data set. Also, the frequency components lower than 0.001 Hz of them were reconstructed, and the relationships between shoreline change rate, wave energy flux and longshore current velocity were considered. The shoreline change rate has correlations with the wave energy flux and the longshore current velocity. Moreover, the comparisons of the wave energy flux and the longshore current velocity suggested that the shoreline change rate was influenced by both the wave energy flux and the longshore current velocity.
