Abstract

Formulation and application of a procedure for characterizing the spatial distribution of aperture within a single fracture in rock are discussed. A simultaneous-inversion approach is used to construct the aperture distribution that best replicates the variability apparent in measured hydraulic and electrical data. The procedure is applied to data obtained from laboratory tests conducted on a natural fracture in granite. Three aperture distributions with similar macroscopic characteristics are inferred from the data. Corroboration of these distributions is obtained from the simulation of tracer transport within the fracture and comparison of the simulated results with measured data. -from Authors
