Wasp is a variable complexity modeling system

WASP is a Variable Complexity Modeling System

  • When building a water body model, adjust complexity to match the problem.

    • More Complex Aquatic Systems

    • More Complex Chemical or Interaction

    • More Complex Management Questions


Components of a complex water body modeling framework

Components of a Complex Water Body Modeling Framework

  • Watershed loading models

  • Hydrodynamic and transport models

  • Contaminant fate models

  • Food web bioaccumulation models


Processes that control complexity

Processes that Control Complexity

  • Network Spatial Variability

  • Time Variability

  • Transport Patterns

  • Loading Patterns

  • Chemical Interactions


Wasp transport scheme

WASP Transport Scheme

  • Six Different Flow Fields

    • Surface Water

    • Porewater

    • 3 Solids Transport Fields

    • Evaporation/Precipitation


Wasp transport scheme1

WASP Transport Scheme

  • Flows in WASP can be

    • Specified in the input dataset

    • Read from a hydrodynamic interface file created by another model or program
