Calibrated Unsaturated Zone Properties

The purpose of this report is to document the calibrated property sets for unsaturated zone (UZ) flow and transport process models (UZ models). The calibration of the property sets is performed through inverse modeling using a previously validated model. This work followed, and was planned in Technical Work Plan for: Unsaturated Zone Flow, Drift Seepage and Unsaturated Zone Transport Modeling (BSC 2006 [DIRS 177465], Sections 1 and 2.1.2). However, this analysis report deviates from the technical work plan (TWP) (BSC 2006 [DIRS 177465]), which states the calibrated property sets are to be documented as an appendix to UZ Flow Models and Submodels (SNL 2007 [DIRS 175177]). The deviation is that this analysis is documented as a separate analysis report. This deviation is expected to improve the efficiency of documentating the analysis activities, and reviewing and checking the document. Direct inputs to this report were derived from the following upstream analysis and model reports (Section 4):
• Analysis ofHydrologic Properties Data (BSC 2004 [DIRS 170038])
• Development of Numerical Grids for UZ Flow and Transport Modeling (BSC 2004
[DIRS 169855])
• Simulation of Net Infiltration for Present-Day and Potential Future Climates (SNL 2007 [DIRS 174294])
• Geologic Framework Model (GFM2000) (BSC 2004 [DIRS 170029].
