AB: The boundary conditions for the base-case and alternate conceptual site-scale saturated zone flow models for the area surrounding the Yucca Mountain repository are specified through analyses of the Death Valley Regional Flow System (DVRFS) models, the site-scale unsaturated zone (UZ) models, and recharge below Fortymile Wash. The base-case site-scale saturated zone flow model is supplied data that are extracted from the 1997 DVRFS, the 1997 UZ model, and from data relating to infiltration through Fortymile Wash. The alternate conceptual site-scale saturated zone flow model is supplied data extracted from the 2001 DVRFS, the 2003 UZ model, and again from Fortymile Wash. Corrected total infiltration rates for the base-case site-scale saturated zone flow model total 24.4~kg/s with 6.7~kg/s coming from below the 1997 UZ model footprint and 2.0~kg/s from flow infiltrating through Fortymile Wash. Infiltration into the alternate conceptual site-scale saturated zone flow model is 77.3~kg/s with 5.6~kg/s coming from below the 2003 UZ model, and 1.9~kg/s through Fortymile Wash. Lateral recharge flux target boundary conditions are extracted from the 1997 DVRFS for the base-case saturated zone site-scale model and from the 2001 DVRFS model for the alternate conceptual model saturated zone site-scale model and both distributions and magnitudes vary greatly. {\st This work was supported by the Yucca Mountain Site Characterization Office as part of the Civilian Radioactive Waste Program, which is managed by the U.S. Department of Energy, Yucca Mountain Site Characterization Project.
