A porous block of volcanic tuff with an embedded fracture was used to perform laboratory-scale water and gas flow experiments for the purpose of obtaining unsaturated fractured rock characterization parameters. Rock matrix properties included porosity, hydraulic diffusivity and the gas-phase diffusion coefficient. Fracture properties included apertures, transmissivity, hydraulic conductivity, and air-entry pressure. Gas tracer experiments using argon and helium are presented for estimating fracture hydraulic conductivity, fracture apertures and rock matrix porosities. 4 refs., 3 figs., 1 tab.
