Effect of Wave Height on Cross-Shore Solute Mixing

Abstract

The investigations reported relate to a series of hydrodynamic and fluorometric tracing experiments carried out in the U.K. Coastal Research Facility, located at H. R. Wallingford Ltd. Detailed measurements were made to examine the cross-shore spreading of a solute mostly outside the surf zone for shore-normal waves combined with a long-shore current. Data are presented that characterize the solute transport processes and quantify the contribution of wave activity to the mixing processes in the coastal zone. Results suggest that the mixing increases with the square of the wave height,
