Abstract
Two numerical simulation techniques have been used to identify a suitable method to assist in the characterization of DNAPL movement within fractured porous rock aquifers. Both MODFLOW and UTCHEM software modeling suites were used to simulate different scenarios in fracture dip and hydraulic conductivities. The complexity and the physical structure of fracture characterization were shown to have a significant effect on modeling results, to the extent that fracture zone should be characterized fully before simulation models are used for DNAPL simulations. Sensitivity analysis was conducted on both the hydraulic conductivity and fracture dip values. DNAPL movement in the subsurface showed a high sensitivity to fracture dip variation.
