TL;DR: In this paper, the authors proposed a variable density flow and solute transport simulation of aquifer systems containing narrow transition zones between freshwater and saltwater using Galerkin finite element methodology.

TL;DR: In this article, a simulation-management methodology is demonstrated for the rehabilitation of aquifers that have been subjected to chemical contamination, where finite element groundwater flow and contaminant transport simulation are combined with nonlinear optimization.

TL;DR: It is shown that, on the basis of current greenhouse gas emission rates, the nonlinear interactions between sea-level rise and wave dynamics over reefs will lead to the annual wave-driven overwash of most atoll islands by the mid-21st century.

TL;DR: In this article, the U.S. Geological Survey's SUTRA computer code was modified to simulate fully saturated, coupled porewater-energy transport, with freezing and melting pore water, and includes proportional heat capacity and thermal conductivity of water and ice, decreasing matrix permeability due to ice formation and latent heat.
