Aspects of SIMSYS2D
A System for Two-Dimensional Flow Computation
SIMSYS2D is a system for two-dimensional simulation of hydrodynamics and water quality in well-mixed estuaries, coastal seas, harbors, and inland waters. It uses the vertically integrated hydrodynamic and transport equations of dissolved substances and computes the land-water boundaries from the local water levels and depths. The system has many features that allow rapid engineering investigations. Nearly all location-dependent variables can be mapped during or after a simulation, and all time series can be plotted in many ways using menu-driven plot programs. The structure of the system is very flexible and permits insertion of other computational algorithms. Experience has shown that hydraulic engineers can operate the system effectively after only a few days' instruction.
