Abstract
Studies on the groundwater flow in fractured rocks were reviewed, with a focus on breakthrough, mixing and dispersion properties of the tracer (or solute) in fractures. A few findings obtained from collective analyses of the published results are shown. Many previous papers using the tracer approach showed breakthrough curves with a rapid concentration peak followed by a tailing. Referring to the available test results, the present paper demonstrates that the peak arrival time and the recovery time (or the tailing duration) are highly correlated with R2=0.82. A comprehensive rearranging of much data on longitudinal dispersivity reported in the literatures revealed that there existed a significant positive correlation between the dispersivity and the testing scale with R2=0.76.
