... the aperture distribution. The mean apertures of fracture specimens are obtained by conducting statistic analysis on the aperture distributions. Constant hydraulic head flow tests on fracture specimens are also performed for inversion calculation of the hydraulic aperture. Comparisons between the mean aperture...
