Abstract: The program for a two dimensional finite difference estuarine model was adapted for use on a modified IBM-PC/XT microcomputer. Commercially available hardware and supporting software were used to expand the working memory of an IBM-PC/XT to 2 megabytes, and to create a 32 bit microprocessor with computational speeds comparable to those of a VAX 11/750 and 11/780 for simple arithmetic operations. Previous applications of the model, written in FORTRAN, had been restricted to IBM, AMDAHL, and Sperry UNIVAC mainframe systems. Use of the model on the microcomputer was successful and produced useable results. The application of hardware and software, including a brief description of the hydrodynamic model, is presented. Operating lessons learned from the use of microcomputers for this type of modeling application are also discussed.
