Book Description
As a part of the New York (NY) Bight Feasibility Study, a three-dimensional, time-varying numerical hydrodynamic and transport model of the NY Bight was developed by the U.S. Army Engineer Waterways Experiment Station. For this purpose, the three-dimensional hydrodynamic model CH3D-WES was used, along with a boundary-fitted grid in the horizontal and 5-10 sigma layers in the vertical. The model was calibrated and verified with the field data measured in April and May 1976. As a demonstration of the feasibility of long-term simulation, hydrodynamics and transport were modeled for the period April - October 1976. Model results were furnished as input to a water quality model of the NY Bight, which reproduced successfully the hypoxic event of 1976. This user's reference manual presents a brief description of the theory of the numerical model and its various features. The structure of the computer code, the function of various subroutines, the formats of input data, various data files required, and available output options are described in detail. For illustrative purposes, sample listings of input files are furnished for an example case simulating hydrodynamics and transport in the NY Bight for the month of April 1976. (AN).
