✦ Synopsis

The mathematical base of the double porosity concept, consisting of the continuity and equilibrium equation respectively, is briefly reviewed. A quasi-steady-state transfer function, the so-called leakage term, is used. Important aspects of the developed code, based on the double porosity theory, are presented together with two hypothetical example problems. The resulting trend of the settlements are compared to those from previous work and was found to be significantly different. However, the implications are that the present study exhibits a more realistic prediction for the settlement.

## Abstract A new discrete‐fracture multiphase flow model developed allows incorporation of fractures in a spatially explicit fashion. It is an alternative to conventional dual‐porosity, dual‐permeability models used most often to model fractured subsurface systems. The model was applied to a water
