Abstract
Numerical wave refraction programs permit a detailed study of the transformation of wave energy as waves move from deep water to shallow water. By eliminating the subjectivity that is present with hand drawn diagrams the effect of small variations in the initial assumptions and wave conditions can be investigated. The effects of wave refraction of tide level changes and bottom friction are investigated here. It is demonstrated that a uniform increase in water level as would be caused by tidal fluctuations can cause a significant change in the wave refraction pattern for a given nearshore region. A computing procedure in developed to permit numerical refraction programs to account for bottom friction. The reduction in wave height caused by bottom friction depends primarily on bottom slope; this relation is shown in tabular and graphical form.
