Offshore design often involves the use of maximum wave height for a given water depth, yet the presence of a current is usually neglected. A constant current, having the same magnitude over the water depth, can be simply included in design by relating the wave propagating on a current to an equivalent wave propagating in still water. By relating the maximum height values for still water to those on a current, a breaking index curve is generated for waves on uniform currents. The effect of the current on the wave crest displacement is also examined. Finally, a curve is presented to show the magnitude of the maximum opposing currents for which wave groups can propagate upstream. Two examples are provided to illustrate the use of the results.
