(emsl2558)Parameterization of Subsurface Flow and Transport Models for Multi-Scale Simulation
EMSL Project ID
2558a
Abstract
Field-scale modeling of multi-fluid flow and transport processes in subsurface environments to address DOE's contaminant remediation and waste management problems generally involves one or more of the following conditions: (1) large simulation domains, (2) the need to assess the integrated effects of contaminant migration from multiple waste disposal sites, (3) lack of data characterizing the small-scale variability of highly heterogeneous subsurface materials, and (4) a general requirement to assess uncertainties in the modeling results. Accurate parameterization and simulation of very large domains containing highly heterogeneous sediments has proven to be a particularly challenging problem, from both experimental and computational standpoints. The primary objectives of this research are: (1) to develop a framework and software tools for systematizing the process of model parameterization for multi-scale simulation of multi-fluid flow and transport processes in the heterogeneous subsurface, (2) to develop new methods and algorithms for estimating effective (upscaled) model parameters, and (3) to test and refine the methods by comparing simulation results to data from well-controlled field experiments.
