FIELD OBSERVATIONS OF SEDIMENT PARTICLE MOVEMENTS IN THE SWASH ZONE USING FLUORESCENT SAND

Abstract

Many studies have been conducted to investigate sediment transport mechanisms in and out of surf zones. However, detailed studies on sediment transport dynamics that track the movement of each sediment particle in the swash zone are limited. In this study, fluorescent sand tracers were introduced into the surf and swash zones, and sand in the swash zone was sampled every few hours. In addition, the currents and wave heights were observed to investigate the sediment movement dynamics in the swash zone.
