Abstract:
One approach for modeling saturated and unsaturated flow in natural rock fractures is to employ a discrete fracture model, wherein a fracture network is built on assumptions for aperture frequency distributions, fracture spacings, and fracture connections. My research was undertaken to attempt to validate the discrete fracture approach by studying the aperture configuration of a natural fracture in welded tuff to determine if any characteristic properties could be identified. The objectives of my research were threefold: (1) to profile the surface of a fracture, (2) to develop and demonstrate a methodology for translating profiles of fracture surfaces into an array of apertures, and (3) to analyze the statistical properties of the calculated apertures to identify characteristic properties. The results of my research suggest that characteristic properties measured for a single section of a fracture cannot be readily extrapolated to adjacent sections, let alone the fracture as a whole.
