Abstract	Abstract : This report describes the operation and use of a new numerical model, GNWave. This model was designed to simulate the evolution of a train of two- dimensional waves in waters of arbitrary bottom topography, varying from shallow water to waters of moderate depth. The program uses the Green-Naghdi theory of fluid sheets as its model, and integrates a set of coupled, nonlinear partial differential equations in time to perform the simulation of surface gravity waves. Report 1 in this series, entitled 'Application of the Green-Naghdi theory of fluid sheets to shallow water wave problems', contains a detailed description of the mathematical basis of GNWave model. The model GNWave has been shown to reproduce with engineering accuracy the evolution of a wave of permanent form, from small amplitudes up to almost breaking conditions. The numerical model is portable with little or no changes to a wide variety of platforms, and has successfully been tested on high-end PC's and VAX and CRAY mainframe systems. The governing equations were programmed using Fortran as the language. The program consists of a main program and a number of modules to perform the calculations. A functional flow chart of individual routines involved in the computation is included herein. The main routine directs the sequence of the calculation, including the reading of the input and integration of the equations, and performs some post-processing.
