The Chapman Conference will focus on the following questions, grouped into two major categories, using results from field-scale experiments in highly heterogeneous aquifers as one basis for discussion:

1. What have we learned from field-scale tracer experiments in highly heterogeneous aquifers and where do we go from here?

  • What are the key physical processes and transport mechanisms at MADE and other well-studied sites?
  • Can those processes be identified with the aid of models based on different conceptualizations?
  • What have we learned about the effectiveness of various aquifer characterization strategies to provide the data necessary to predict various aspects of plume behavior (e.g., longitudinal mass distribution, local concentration, solute flux)?
  • How can we use field experiment results to help guide the design of future experiments (e.g., density and extent of measurements) at highly heterogeneous sites?
  • How can we improve experimental techniques (e.g., well tests, direct-push profiling, geophysics) and adapt them to the prediction of specific transport features?

2. What modeling approaches are most effective for simulating groundwater transport through highly heterogeneous media and quantifying associated uncertainties, and what information is needed to parameterize these models?

  • Can transport models underlain by the local advection-dispersion equation (ADE) provide adequate prediction of transport when coupled with aquifer data of sufficient detail?
  • Are there promising alternative models that could be used in a predictive fashion, without calibration to tracer data?
  • Can models be developed that predict local concentration distributions statistically, rather than global measures of the plume solely?
  • Can models be extended to more complex flows (e.g. unsteady, slowly varying in space, flow to a pumping well)?
  • How can we best characterize and incorporate other processes such as retention (mass transfer) and transformation (biodegradation) into transport models?

The conference will include morning and evening oral sessions.  The arrangement of the sessions will depend on the number of contributions.  All oral sessions would be in a plenary format.  Posters would be on display throughout the conference but, beginning with the morning session on Day 2, mid-morning breaks would be designated specifically as times for authors to be at their posters.

Fields of Interest

We encourage researchers who have been directly involved in field-scale transport experiments at MADE and elsewhere and others working on aquifer characterization and contaminant transport modeling to attend. We aim to draw a variety of participants ranging from senior to early-career scientists and graduate students.
