The Most Versatile Surface Water and Contaminant Transport Modeling Software Commercially Available!
AQUASEA is a software package developed to solve the shallow water flow and transport equations using the Galerkin finite element method. AQUASEA was first developed in 1983 to solve two-dimensional problems, and since 1992, it has been continuously upgraded and tested worldwide on the most difficult modeling problems. The latest development of AQUASEA is a version which runs in Windows 95/98/2000 or Windows NT. It has been specifically configured and compiled to provide maximum efficiency in model set up and fast model run times. The Windows environment provides not only a multi-platform capability but also an assured industry-standard user interface for future developments. AQUASEA consists of the following two models:
The AQUASEA flow model can simulate water level variations and flows in response to various forcing functions in lakes, estuaries, bays and coastal areas. The water levels and flows are approximated in a numerical finite element grid and calculated on the basis of information on the bathymetry, bed resistance coefficients, wind field and boundary conditions.
The AQUASEA transport-dispersion model simulates the spreading of a substance in the environment under the influence of the fluid flow and the existing dispersion processes. The substance may be a pollutant of any kind, conservative or non-conservative, inorganic or organic salt, heat suspended sediment, dissolved oxygen, inorganic phosphorus, nitrogen and other water quality parameters.
Tidal Flow in Estuaries and Coastal Areas, Wind-Driven Circulation in Lakes and Harbor Oscillations. The main input into this model consists of the bed bathymetry which can be digitized directly from admiralty charts. Rivers and outlets may be included as point sources. Wind stress may vary in space and time.
Transport of Mass, Heat and Suspended Sediment. The transported matter can be biological, radioactive, thermal, saline, or suspended sediment. Subsequent behavior might include decay of biological or radioactive matter, the cooling of the thermal flow or the settling of the suspended material.
AQUASEA has a restart capability which means that the solution of the flow or transport equation can be stopped at any stage and the calculated results observed. The program can then be restarted.
AQUASEA is based on the solution of the two-dimensional shallow water equations including bed resistance, wind stress, Coriolis force, and nonlinear convective terms. The transport model includes sources, decay, and convective and dispersive transport.
Minimum requirements for practical use are a Pentium computer with a 166 MHz processor, 32 MB of RAM, 250 MB hard disk and Windows 95/98/2000 or Windows NT.
