Turbulence Dynamics in Irregular Breaking Waves

Abstract

Our long-term goals are to provide a detailed picture of the breaking and decay of irregular waves in a laboratory surf zone, and of the generation and evolution of the related turbulent flow fields. Our current work focuses on measurement of the temporal and spatial distributions of wave-induced stresses and turbulent stresses under regular and irregular waves on a plane beach using a two-component laser Doppler anemometer (LDA), and measurement of coherent structures under breaking waves using a stereoscopic particle image (PIV) velocimetry system.
