ABSTRACTThe present status of the recently introduced gas method equipment for migration studies of fractured and porous media is briefly reviewed together with advances in the experimental techniques. The conditions under which matrix diffusion can be observed in both gas flow and water flow experiments are discussed in some detail. Results for a gas flow experiment are shown, and explained with a numerical model which incorporates the effects of hydrodynamic dispersion and matrix diffusion. The necessary parameters for a corresponding water flow experiment are also briefly discussed.

1. INTRODUCTION. Interest in the use of video displays for nautical chart presentation has increased rapidly during the last two years. Eaton et al. at the Second International Hydrographic Technical Conference provided a list of ten different systems already in production. Oshima speaking at a Workshop on the subject in Canada, early in 1985, mentioned that some 4000 Japanese fishing boats and 150 merchant vessels now carry electronic charts of varying degrees of complexity.
