The evaluation of the advection-dispersion in fractures and diffusion into the matrix from fractures is important to describe the mass transport processes in fractured porous media such as sedimentary rocks. However, it is often difficult to uniquely determine a number of parameters relevant to these phenomena, such as fracture aperture, dispersivity coefficient, and matrix diffusion coefficient, from a data set of a single tracer test. In this paper, a one-dimensional multiple tracer test for single fracture in a sedimentary rock block was conducted under the condition of injection rate for the unique parameter estimation suggested by authors. And the new efficient test procedure using both multiple tracer and multiple flow rate tests was suggested.
