Abstract : The report presents an operational description of the single-layer vertically integrated Hydrodynamical-Numerical (HN) model. The model is an adaptation of one developed by Professor Walter Hansen, University of Hamburg, and tested over the course of two decades. The description includes the setting up of the model for a given area and the selection and preparation of input data. A brief background of the hydrodynamical formulas and their finite difference forms are also presented. For coastal applications, it is now possible to run the model with three open boundaries. Another new feature makes possible the inclusion of the permanent (thermohaline component) current as well as tidal and wind currents. The transport and diffusion equation is included in the new program. Thus, the program can be used for computing the distribution of pollutants. The program (see Appendix C) is written in FORTRAN and thus will run on almost any computer. (Modified author abstract)
