SIMSYS2D: A Two-Dimensional Flow and Water Quality Simulation System

The SIMSYS2D system is designed for the two-dimensional simulation of hydrodynamics and water quality in well-mixed estuaries, coastal seas, harbors, and inland waters. The system can simulate the hydrodynamics in complicated geographical areas and the land/water boundary is determined by the model during simulation. The system accounts for sources of discharges, for tidal flats, for islands or dams, for time varying or time invarying flow restrictions in which sub or super critical flow occurs and such as generated by openings in dams, sluices, or stormsurge barriers. The system is designed for planning, design and execution of engineering works and for the assessment of the impact thereof. The input and results of simulations are well documented in printed reports and graphical displays. The latter are of high quality and can be incorporated in engineering reports. The SIMSYS2D system consists of nine programs; data is passed between these programs. In addition to these programs, a number of programs for extended data processing and data input preparation are being used.
