Uncertainty analysis for seawater intrusion in fractured coastal aquifers: Effects of fracture location, aperture, density and hydrodynamic parameters
Behshad Koohbor,Marwan Fahs,Behzad Ataie-Ashtiani,Behzad Ataie-Ashtiani,Benjamin Belfort,Craig T. Simmons,Anis Younes,Anis Younes +7 more
TL;DR: In this article, the authors used polynomial chaos expansion (PCE) to perform uncertainty analysis for seawater intrusion in fractured coastal aquifers (FCAs) which is simulated using the coupled discrete fracture network (DFN) and variable-density flow (VDF) models.

Comparison of Equivalent Conductivities for Numerical Simulation of One-Dimensional Unsaturated Flow
TL;DR: In this paper, a mixed hybrid finite element solution with different formulations for the equivalent hydraulic conductivity in an attempt to more accurately simulate variably saturated flow was implemented for sharp infiltration fronts.
An efficient lumped mixed hybrid finite element formulation for variably saturated groundwater flow.
TL;DR: In this paper, the authors used the mixed hybrid finite element (MHFE) method, which allows a simultaneous approximation of both pressure head and velocity and can handle general irregular grids with highly heterogeneous permeability.

TL;DR: In this paper, Younes et al. proposed a new mass-lumping scheme for the mixed hybrid finite element (MHFE) method for unsaturated groundwater flow, which can simultaneously approximate both the pressure head and its gradient.

On equivalent hydraulic conductivity for oscillation–free solutions of Richard’s equation
TL;DR: An adaptive algorithm is presented, which adapts the conductivity in function of the monotonicity condition, i.e., a variable criterion based on the Conductivity averaging technique and the piezometric head variation, which can be implemented in existing multidimensional codes.
