Description:

The proposed project activities include:

·Development of a high performance groundwater flow model based on the analytic element method (AEM), with an emphasis on MPI-based portability.
·Development and comparison of automated calibration/optimization tools based on: 1) nonlinear regression and 2) the genetic algorithm.
·Development of a GIS-based graphical user interface for the modeling system.
·Extensive testing of the modeling system on 3 high-performance parallel computing platforms: the SGI Origin, the IBM SP, and a heterogeneous Sun workstation cluster.
·Application of the modeling tools to a case study of regional groundwater flow in the Niagara Falls/Lake Ontario region, including comparisons with previous efforts based on the traditional finite difference approach.

Expected Results:

In addition to research reports and journal articles documenting the above activities, the project will produce a public domain modeling system that has been extensively tested on 3 leading edge massively parallel platforms, thus ensuring portability to nearly any parallel environment. The calibration/optimization algorithm will take advantage of the unique features of AEM and the inherently parallel genetic algorithm, thus extending the power of automated inverse methods to very large-scale regional problems. The project will also promote the development and use of AEM models through a national workshop and regional distance learning course, and be coordinated with concurrent EPA initiatives in ecosystem modeling, particularly the Multimedia Integrated Modeling System (MIMS).
