Abstract

Double-porosity is an important characteristic in soil that is found to influence the migration of fluids within the soil. Of late, a number of laboratory experiment studies have been carried out on the flow of water through soil media with double-porosity characteristics as well as on the mechanical aspects of the double-porosity structure of the soil. This paper first introduces the double-porosity concept as apposite to soil and then presents a review of the experimental studies mentioned. It is concluded that there is still a significant gap in the literature with regards to laboratory experiments conducted in double-porosity soil using liquids that are immiscible with water.

 

Key words: Aggregated soil, dual-porosity, fluid flow, porous media.
