Network Flexibility Applicable to most water body types at some level of complexity 0D, 1D, 2D, 3D including branching

Most Water Quality Problems Conventional Water Quality: DO, nutrients, eutrophication, heat Toxicants: organics, metals, mercury-specific module

Separation of Processes

Transport (Advection, Exchange/Dispersion, Solids) Kinetics

External Links to Models and Spreadsheets Has internal, simple hydrodynamic modeling approaches for water

routing Dams and impoundments Tidal influence and reverse flows

WASP AdvantagesWASP Advantages


5/11


Does not handle some variables and processes: Segment drying (mudflats, flood plains) Metals speciation reactions (special module, META4),

Calculations done outside WASP and then transferred in Currently limited to 3 chemical species and 3 solids types

Potentially large external hydrodynamic files Forces WASP delineation and time steps

Separate eutrophication and toxicant fate modules Cannot readily be run in batch mode

Requires manual calibration and parameter estimation and

sensitivity and uncertainty analysis Introduction of new algorithms and processes can be slow and

limited to the current WASP architecture.
