- Summary
- A numerical model is presented to simulate compaction of shallow groundwater systems. The model combines a general three-dimensional fluid flow field with a one-dimensional deformation of the porous medium. The governing equation is solved with an Integrated Finite Difference Method using a mixed explicit-implicit iteration scheme for advancing in the time domain. The model can handle heterogeneous flow regions with complex geometry, and with time dependent variation of material properties and boundary conditions. Five illustrative examples are provided to demonstrate the applicability of the model to problems of relevance in studying land subsidence.
