MIGRATEv10 vs POLLUTEv10: Fractured Layer with Sorption Comparison
Overview This example compares results from MIGRATEv10 and POLLUTEv10 for a fractured soil layer with sorption. This is one of the more complex transport scenarios, combining: The result is a system where contaminants can move rapidly through fractures while simultaneously being retarded and stored in the soil matrix. Model Setup Both models simulate a two-layer…

MIGRATEv10 vs POLLUTEv10: Finite Mass Source Comparison
Overview This example compares finite mass transport results from MIGRATEv10 and POLLUTEv10. Unlike constant source cases, this scenario represents a limited contaminant inventory, where concentrations rise, peak, and then decline as the source is depleted. The key objective is to evaluate how both models predict: Model Setup Both models use identical physical conditions: This configuration…

MIGRATEv10 vs POLLUTEv10: Pure Diffusion Comparison
Overview In this example, we compare pure diffusion results generated using MIGRATEv10 and POLLUTEv10 under identical conditions. The objective is to verify consistency between the two models and highlight key differences in their capabilities. Both simulations consider contaminant transport through a 4 m thick layer under pure diffusion (no advection), with constant concentration boundary conditions…

MIGRATEv10 vs POLLUTEv10: Advective–Diffusive Transport Comparison
Overview This example compares advective–diffusive transport results from MIGRATEv10 and POLLUTEv10 using identical input conditions. The goal is to evaluate consistency between the two models while highlighting key differences in how they represent contaminant transport. Unlike pure diffusion, this case includes advection, resulting in much faster contaminant migration and earlier breakthrough at depth. Model Setup…

MIGRATEv10 vs POLLUTEv10: Hydraulic Trap (Finite Mass Source) Comparison
Overview This example compares results from MIGRATEv10 and POLLUTEv10 for a hydraulic trap scenario with a finite mass source. A hydraulic trap occurs when upward (negative) advective velocity counteracts downward contaminant migration. In this case: This creates a system where contaminants are partially retained, significantly altering breakthrough behavior compared to standard downward flow cases. Model…
