AN EXPERIMENTAL STUDY OF FLOW CHARACTERISTICS IN AN ARTIFICIAL HOLLOW REEF

Abstract

A series of experiments for understanding hydraulic characteristics inside of artificial hollow reef was conducted. The mean velocity and turbulent components in the reef were measured by the Particle Image Velocimetry (PIV). The dependence of wave characteristics are investigated for estimation of transmission coefficinets of the incident waves. The experimental data shows steady offshore current in the reef and indicates the downward flow into the mound of the reef.
