10. EQM 002: Parallel TABS MDS Model for Simulating Large Scale Environmental Transport Processes • Funding Status: Fully funded at $170,665 over 11/01/01 — 9/30/02 • P.I.: Prasada Rao • Civil & Environmental Engineering • Duke University, Durham, NC Objective: To deliver a parallel version of TABS MDS model integrated with an iterative solver and preconditioner • EQM002 Milestones—progress: • The code now has an accurate parallel iterative solver. • The parallel code development is in progress • EQM002 Deliverables • The work is progressing satisfactorily with no problems thus far • The parallel code will be delivered in 09/02 Contract Year 1 Review

11. EQM 003: Enhancements to the Adaptive Hydrology Model and CE-QUAL-ICM In this project, we will provide enhancements to the Adaptive Hydrology (ADH) Model, a hydrodynamics code written by engineers at the ERDC, and CE-QUAL-ICM, a water quality model also developed at the ERDC. The planned enhancements include incorporation of reactive strategies and air-water models and transport methods in CE-QUAL-ICM • Funding Status: Fully funded at reduced level of $128,506 over 11/01/01—10/30/02 • P.I.: Mary Wheeler and Clint Dawson • EQM003 Milestones—progress: • Reactive transport module delivered to Charlie Berger in January 2001 for incorporation into ADH • DG methods implemented for transport in CE-QUAL-ICM and ADCIRC • Two-phase air-water model developed • EQM003 Deliverables • Written progress reports • Incorporation and testing of DG and other two-point, upwind schemes in CE-QUAL-ICM and reactive transport module incorporated into ADH • Comparison to Richards’ equation model Contract Year 1 Review

13. Staffing • Mary Wheeler is FAPOC • Clint Dawson is Sr. Researcher • Phu Luong was on-site from inception through 18 Feb 2002 • Jeff Hensley assumed on-site duties 15 Apr 2002 • Victor Parr has been on staff since inception • Two post-doctoral researchers will be leaving in the summer, to be replaced shortly thereafter • Two graduate students have also been employed Contract Year 1 Review

14. Summary • Much time and effort spent getting contracts in place • EQM on-site staffing in good shape • Projects are proceeding as planned, with reduced efforts due to budget cuts • EQM team members are highly visible in the community and involved with DOD users • Some projects, identified as high priority by EQM users, have been cut drastically;  e.g., multiphysics couplings and conservative projections algorithms (UTPROJ) • Funding issues have made staff retention and planning difficult Contract Year 1 Review
