MIGRATEv9 INTRODUCTION
Using the MIGRATEv9 software, contaminant transport from multiple sources, either at the surface or buried, can be modeled quickly and accurately in two
dimensions.
Unlike finite-element and finite-difference formulations, MIGRATEv9 does not require the use of a "time-marching" procedure. MIGRATEv9 uses a finite-layer
technique that provides numerically accurate and stable results while requiring relatively little computational and data entry effort.
In addition to advective-dispersive transport, MIGRATEv9 can consider sorption, radioactive and biological decay, and transport through fractures. One or more
landfills, buried waste deposits, spills, or disposal ponds can be modeled. These contaminant sources may be adjacent or offset from each other. Model properties may be either constant or transient, with the concentrations
calculated at specified times, depths, and distances.
MIGRATEv9 APPLICATIONS
- Automatically calculate the maximum plume concentration at any time, depth or distance.
- Model contaminant transport through fractured layers.
- Model extensions to existing landfills.
- Demonstrate the effects of varying waste facility cover strategies.
- Perform risk assessment for soil management programs.
MIGRATEv9 STANDARD FEATURES
- Model contaminant sources as surface boundary conditions or as a physically buried layer.
- Have the source concentration deplete with time or remain constant.
- Remove leachate using a leachate collection system.
- Specify both horizontal and vertical velocities and hydrodynamic dispersion coefficients for each layer.
- Model nonconservative species using linear sorption.
- Include 1-D, 2-D, or 3-D fractures in any layer.
- Simulate secondary leachate collection systems using a passive sink in any layer.
