WATER QUALITY ANALYSIS SIMULATION PROGRAM
Description:
The Water Quality Analysis Simulation Program (WASP6), an enhancement of the original WASP (Di Toro et al., 1983; Connolly and Winfield,1984; Ambrose, R.B. et al.,1988). This model helps users interpret and predict water quality responses to natural phenomena and man-made pollution for various pollution management decisions. WASP6 is a dynamic compartment-modeling program for aquatic systems, including both the water column and the underlying benthos. WASP allows the user to investigate 1, 2, and 3 dimensional systems, and a variety of pollutant types. The state variables for the given modules are given in the table below. The time-varying processes of advection, dispersion, point and diffuse mass loading and boundary exchange are represented in the model. WASP also can be linked with hydrodynamic and sediment transport models that can provide flows, depths, velocities, and temperature, salinity and sediment fluxes.
WASP has been used to examine eutrophication of Tampa Bay, FL; phosphorus loading to Lake Okeechobee, FL; eutrophication of the Neuse River Estuary, NC; eutrophication Coosa River and Reservoirs, AL; PCB pollution of the Great Lakes, eutrophication of the Potomac Estuary, kepone pollution of the James River Estuary, volatile organic pollution of the Delaware Estuary, and heavy metal pollution of the Deep River, North Carolina, mercury in the Savannah River, GA. WASP is routinely used for TMDL determinations and waste load allocations.

Model Detail:
Model Evaluation
:WASP has been tested against analytical solutions, and has been peer reviewed by such groups as the National Council on Air and Stream Improvement (NCASI), Army Corp of Engineers, South Florida Water Management District.
The model has an application history that spans 30 years and is used routinely in the US and world.

Model Guidance Documents
:Watershed and Water Quality Modeling Technical Support Center maintains a WASP Users Manual and is included with the installation package. The Users Manual is periodically updated as the model is enhanced.
Model Decision Documents
:WASP has been routinely used throughout the US and World for water quality modeling. Searches of the literature should provide more details about specific applications of the model.

Model Inputs
:Waterbody segmented in computational boxes, forcing functions such as: flow, dispersions, boundary concentrations, water temperature, light, kinetic constants and initial conditions. More complex the application the greater the input requirements.
Model Outputs
:User selects the output variables from the model. All model output can be viewed using a graphical/tabular post processor that is included with the model. It is easy to take results from the WASP model to other models or other software for analysis and/or publication.
Model Computer Requirements:
Model Operating Systems Needs
:Microsoft Windows 95 or Higher
Model Hardware Needs
:Standard Desktop System. Higher performance machine maybe need for large simulations.
Model Programming Language(s)
:Graphical User Interface and Model Post Processor C++, utility programs and simulation models FORTRAN.
other_req
:Optional Software Water Resources Database (WRDB). Database designed to store environmental information; WASP can query time series data from WRDB or plot model predictions vs. field data stored in WRDB.
