Bioremediation of tetra-and trichloroethene-contaminated aquifers is requently hampered due to incomplete dechlorination to the more toxic dichloroethene (DCE) and vinyl chloride (VC), indicating insufficient knowledge about the biological mechanisms relat ...
Semi-analytical solutions are presented for flow to a well in an extensive homogeneous and anisotropic unconfined-fractured aquifer system separated by an aquitard. The pumping well is of infinitesimal radius and screened in either the overlying unconfined ...
Due to the heterogeneity of natural groundwater systems, any quantitative description of aquifer hydraulic properties is subject to uncertainty. Consequently, prediction of groundwater contaminant transport is also subject to uncertainty. Stochastic approa ...
Switzerland is exceptionally subjected to landslides; indeed, about 10% of its area is considered as unstable. Making this observation, its Department of the Environment (BAFU) introduces in 1997 a method to realize landslide hazard maps. It is routinely u ...
The behavior of As in the subsurface environment was examined along a transect of groundwater monitoring wells at a Superfund site, where enhanced reductive dechlorination (ERD) is being used for the remediation of groundwater contaminated with chlorinated ...
Evaluation of aquifer yields with the conventional time- drawdown method is based on the assumption of Theisian or infinite radial flow (IRF) of ground water to a well. However, long-term aquifer yields are controlled by heterogeneities and boundary condit ...
Due to the heterogeneity of natural groundwater systems, any quantitative description of aquifer hydraulic properties is subject to uncertainty. Consequently, prediction of groundwater transport is also subject to uncertainty. Stochastic approaches to tran ...

Groundwater microbial community samples are traditionally collected using pumping techniques optimized for groundwater chemistry assessment, although the impact of groundwater pumping parameters on apparent bacterial community structures (BCSs) is not real ...
A Navier-Stokes hydrodynamic model with a VOF method and a turbulence closure solver was used to simulate wave motion on permeable beaches. Coastal aquifer dynamics, the interactions between the groundwater and the seawater, and the effects of wave motions ...
