Description of the Optimized EPRF Multi-Layer Hydrodynamical-Numerical Model,
Abstract
The multi-layer hydrodynamic-numerical (HN) model described here is a redesigned and optimized version of the multi-layer codes developed by the Environmental Prediction Research Facility (EPRF) using the finite difference scheme. The model described is written in FORTRAN IV for CDC computers. The model is divided into three phases linked by a single intermediate tape. Phase I, which initializes the intermediate tape by writing on it the computed symbolic water height field, the water depth fields at U and V points, and the time O water height and velocity fields, is run on EPRF's CDC 3100 computer. Phase II, which computes time and space dependent terms, is run on either the CDC 6500 or the CDC 7600. Phase III is used to analyze, display and compare printed and plotted model results. It also runs on EPRF's CDC 3100 computer and produces plots on a CALCOMP pen plotter.
