Studies on the wave transformation by currents : -A culculating method of the weve direction and velocity

The equation (8) and (16) were respectively conducted for calculation of wave process and direction in a territory with currents. As a result of calculation applied these equations to the graphical construction method (see reference 4), calculated and experimental values were in conformity for the model (deep water) with free currents (see Fig. 12). Therefore, this calculating method will be a useful technique as to explain a phenomenon of wave behavior (especially the direction of the wave propagation) in the sea region with currents. Although this cannnot explain whether the velocity distribution of model currents coincides with the actual currents or not, presuming to the results of the method applied to the model coast (sea region contained the Shiida land-reclamation), it seems to be generally applied to the any coast (shallow water) with currents.
