A 2-D and 3-D Composite Dimensional Fully Coupled Surface and Subsurface Flow Model

3-d Modeling of Coupled Subsurface Flow-stress by Mixed Finite Elements

The accurate simulation of coupling between flow and stress in saturated porous media is a major issue in a broad variety of fields, ranging from reservoir engineering to biomechanics. Despite the intensive research carried out in recent years, the numerical solution to the partial differential equations governing the behaviour of real fluid saturated heterogeneous porous media still represents...

Heterogeneous Substructuring Methods for Coupled Surface and Subsurface Flow

The exchange of groundand surface water plays a crucial role in a variety of practically relevant processes ranging from flood protection measures to preservation of ecosystem health in natural and human-impacted water resources systems. Commonly accepted models are based on the shallow water equations for overland flow and the Richards equation for saturated–unsaturated subsurface flow with su...

Numerical Modelling of Coupled Surface and Subsurface Flow Systems

This paper presents and compares several numerical solutions of the coupled system of Navier-Stokes and Darcy equations. The schemes are based on combinations of the finite element method and the discontinuous Galerkin method. Accuracy and robustness of the methods are investigated for heterogeneous porous media. The importance of local mass conservation for filtration problems is also discussed.
