dc.descriptionAbstract: This report details an approximate method for calculating the directional spectrum of waves encountering a current in shallow water. The wave trains in the directional spectrum are assumed to be linear and Gaussian; development of the spectrum requires that the Haves also be short crested. The bathymetry is assumed to consist of straight parallel contours. The Miche breaking criterion is imposed to determine the upper limit of wave height and to establish an expression for the breaking wave elevation in terms of the ideal wave's elevation and the second time derivative of elevation. Snell's Law is used for wave refraction. Two examples are given: one for a Hallops directional spectrum encountering a shear current, and one with an upwelling current. Results are presented in graphical form.-
