A Numerical Simulation of Groundwater Flow and Contaminant Transport on the CRAY T3D and C90 Supercomputers

Abstract

Numerical simulations of groundwater flow and chemical transport through three-dimensional heterogeneous porous media are described. The authors employ two CRAY supercomputers for different parts of the decoupled calculation: the flow field is computed on the T3D massively parallel computer, and the contaminant migration is simulated on the C90 vector supercomputer. The authors compare simulation results for subsurface models based on homogeneous and heterogeneous conceptual models and find that the heterogeneities have a profound impact on the character of contaminant migration.
