Book Description
Excerpt from Development of a Method for Numerical Calculation of Wave Refraction A linear-interpolation scheme (using the least-squares method) is used in determination of wave velocity at a given point along a ray. Ray curvature is then calculated at this point and an iteration procedure is solved to obtain the position of the next point. The ray terminates at the shore or grid border. An example of usage of the programs is presented in which 52 rays for waves of 4 and 6 - second period, from six different deep - water origin points, are brought into the Atlantic shore line of the City of Virginia Beach, Virginia. The procedure outlined is in the developmental stage, and suggestions for improvements are given that should offer a quick, accurate, and objective method of constructing wave rays.

Book Description
A procedure is described for calculation of wave refraction using observed or hindcast deepwater wave characteristics, and highspeed computer programs. An example of the method is presented in which wave rays are brought from deep water in the Atlantic Ocean to the shore at Virginia Beach, Virginia. The method is in the developmental stage but promises rapid and accurate calculation for routine determinations. (Author).

Book Description
Reported here is an experimental investigation to assess the limits of applicability of linear wave refraction theory in a convergence zone. One bottom topography with parallel circular contours symmetric about the center of the tank was utilized and three wave periods (1, 2, and 3 sec) were tested along with three wave heights for each period. All tests were conducted for nonbreaking waves. Data were obtained at 100 locations within the model basin for each condition tested. The data were analyzed on the basic assumption that the total energy was equally partitioned between potential energy and kinetic energy. The basic computation performed was to calculate the potential energy transmitted per unit width over one wave period. Measurements of the reflected energy from the underwater topographic variations indicated that such reflections were negligible. This was verified by computations utilizing the long wave theory as well as a theory not requiring the long wave assumption. The theoretical computations indicated that the reflection coefficient was between 0.002 and 0.01 for the 3-sec waves, while the measured data indicated that it was between the scatter of the data (less than 0.02). A computation of the viscous dissipation of energy at the bottom indicated an amplitude attenuation of approximately 3 percent during propagation over the entire length of the measurement area. The experimental data indicated an amplitude attenuation of less than 5 percent due to the combined effects of reflection and bottom friction. ...
