WAVES PRODUCED BY OCEAN-GOING VESSELS: A LABORATORY AND FIELD STUDY

Abstract

In restricted waterways, for example in the St. Lawrence River, the question is raised as to the proportion of river bank erosion caused by shipping as opposed to wind generated waves, tidal currents, and ice break-up. This study is an attempt to ascertain the size of waves, H, and draw-down, A, generated by a vessel as a fraction of the speed, tT, the size and shape of the vessel, of the draught, D, and depth of water, d, and the distance from the sailing line to where the waves are measured, x.
