“…Fracture data from these and other studies in the NTS region are compiled in SNJV (2005c). Fracture data for the tunnel complexes were also collected during investigations for the WTP (e.g., Davis, 1962;Hasler, 1963;and Fairer et al, 1979). Hydrogeologic designations in the RM-SM framework model are based to a large degree on the fracture characteristics described in these data sets.…”
