AQUASEA is a program to solve tidal flow problems in estuaries and coastal areas, lake circulation, and problems involving transport of mass, heat and suspended solids. The package includes various graphical preprocessors to make preparation of data as easy as possible, along with graphical postprocessors. A wide variety of pointing devices (mouse, digitizers, etc.) and hardcopy devices (printers, plotters) are supported through the use of the HALO Professional Graphics Library.

FEATURES


The package can be used without any further knowledge of input and output file formats. File formats, however, are fully documented.
All input files to the AQUASEA package are ASCII files which allow the user to view them with most any text editor. The output files are either ASCII or binary. Utility programs that convert binary files to ASCII files are supplied with the software.
AQUASEA solves transient ground-water flow with inhomogeneous and anisotropic flow conditions. The model can have a large number of pumping and injection wells and areal variation of all parameters. Time variation of pumping/injection and infiltration rate is allowed. Boundary conditions may by prescribed nodal head and prescribed flow as a function of time or head-dependent flow.
AQUASEA solves the transient transport of contaminants and heat with convection, decay, adsorption and velocity dependent dispersion. Boundary conditions may be either prescribed nodal concentration (temperature) or prescribed dispersive mass (heat) flux.
AQUASEA has the ability to calculate both pathlines and timelines to give the user a quick estimate of, for example, transport of contaminants without solving the transport equation.

EXAMPLES AND APPLICATIONS

PROBLEM TYPES

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.
The program 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.
The model 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.

Requirements

486/Pentium with 4 MB RAM, math coprocessor, hard disk, and VGA graphics card and display. Optional hardware supported includes mouse, digitizer, dot matrix and laser printers, and Hewlett Packard or compatible plotters for hardcopy output. A Workstation version is available for UNIX Workstations. AQUASEA includes the executable version, full color graphics, extensive user's manual, and technical support. If you need a version which will do more than 10,000 nodes, please contact us. AQUASEA can run within a DOS environment of Windows.
