Inferring subsurface heterogeneity from push-drift tracer tests
Scott K. Hansen, Velimir V. Vesselinov, Paul W. Reimus +1
We consider the late-time tailing in a tracer test performed with a push-drift methodology (i.e., quasi-radial injection followed by drift under natural gradient). Numerical simula…
Characterizing the impact of model error in hydrogeologic time series recovery inverse problems
Scott K. Hansen, Jiachuan He, Velimir V. Vesselinov
Hydrogeologic models are commonly over-smoothed relative to reality, owing to the difficulty of obtaining accurate high-resolution information about the subsurface. When used in an…
Local equilibrium and retardation revisited
Scott K. Hansen, Velimir V. Vesselinov
In modeling solute transport with mobile-immobile mass transfer (MIMT), it is common to use an advection-dispersion equation (ADE) with a retardation factor, or retarded ADE. This…
CHROTRAN: A mathematical and computational model for in situ heavy metal remediation in heterogeneous aquifers
Scott K. Hansen, Sachin Pandey, Satish Karra +1
Groundwater contamination by heavy metals is a critical environmental problem for which in situ remediation is frequently the only viable treatment option. For such interventions,…
