Pollution transport in coastal regions is controlled by a wide range of fluid mechanical processes, including rip tides and currents. These processes will predominately lead to advection of particles, droplets and bubbles by mean flows. A fundamental mechanism of particle transport by water waves has recently been isolated. Inviscid waves transport neutrally buoyant particles (subject to drag force) with a mean speed in the direction of wave propagation and a mean drift velocity away from the free surface. This has important consequences for pollution transport because buoyant particles and droplets experience a reduced rise speed near the free surface, and there are circumstances when particles are trapped at an equilibrium depth and transported to the sea floor (in shallow waters) where they adhere to sediments.The aim of this project is to study the fundamental question of the effect of how particles, droplets and bubbles are transported by waves under conditions likely to occur in the ocean where wave steepness, chromaticity and randomness are important. A laboratory experimental study is proposed to test the new theoretical descriptions. The validated descriptions will be applied, using published field data on wave characteristics, to predict and aid in the interpretation of field data.
