The theory and numerical methods are presented for determining the paths of gravity water wave packets. A ray curvature expression is used to determine the wave packet trajectories where the speed of the packet is given by G domegadk cos phi. The symbol omega denotes the angular frequency, k is the wave number, and phi is the difference between the direction of the wave packet and the direction of the wavelets within the packet. At each point of the wave packet trajectory the wavelet direction is determined using Snells law with phase velocity. The wave height is computed along the wave packet paths accounting for the effects of shoaling, refraction, and energy dissipation. The computer program is described and sample printouts and plots are presented. Author
