2007 Ground Water Summit

Wednesday, May 2, 2007: 1:00 p.m.-4:00 p.m.
Pecos (Albuquerque Convention Center)
Aquifers and Aquifer Processes, Characterization, and Modeling II
The session is intended for presentations of new ideas, insights, and understanding concerning aquifers, their physical, chemical, and microbial heterogeneity; and processes including flow, reactions, and mass transport. The session will also include presentations of new ideas and approaches for characterizing and modeling aquifers and aquifer processes. A wide range of relevant scales and a wide range of tools for characterization and modeling should be covered among the presentations. The session will highlight the state of both science and professional practice in these areas.
