When we deal with the solute dispersion problems in rock ground, the evaluation of dispersion coefficient becomes important as well as the determination of hydraulic parameters like the permeability. This paper presents how to determine the dispersion coefficient of rocks in a laboratory, and the values of dispersion coefficients for many kinds of rocks collected from different locations in this country were determined by using a newly designed apparatus. The results in this study are summarized as follows : 1) The utility of apparatus proposed in this study was confirmed by the experimental results. 2) The rock dispersion coefficients were 4.75×10^<-6>〜4.80×10^<-9> m^2/s for all rock samples. 3) The dispersion coefficient increases with increasing Reynolds number.
