Abstract : The report documents the incorporation of group velocity into an existing digital computer program which uses phase velocity for calculating gravity water wave rays. Multiperiod rays are used instead of single-period rays. The original gravity water wave refraction program on which this report is based was written in FORTRAN II for the IBM 7094. Development of mathematical expressions that were used to incorporate group velocity into the original computer program are given. (Author)
