A quasi-optimal sparse grids procedure for groundwater flows

In this work we explore the extension of the quasi-optimal sparse grids method proposed in our previous work "On the optimal polynomial approximation of stochastic PDEs by Galerkin and Collocation methods" to a Darcy problem where the permeability is model ...

Material Point Method for Coupled Hydromechanical Problems

Samila Sanjeevanie Bandara

This paper describes a new formulation of the material point method (MPM) for solving coupled hydromechanical problems of fluid-saturated soil subjected to large deformation. A soil-pore fluid coupled MPM algorithm based on Biot's mixture theory is propose ...

On-site biostimulation evaluation of a remediated perchloroethene-contaminated acquifer located in Jablunkov, Czech Republic

Isabelle Fäh

Chlorinated ethenes solvents (CEs) are one of the most common contaminants identified in groundwater ecosystems. Long used as a degreaser in industry, perchloroethene (PCE) and trichloroethene (TCE) are particularly persistent in the environment as recalci ...

Scales and drivers of temporal

Tom Ian Battin, Hannes Markus Peter

The role of inland waters for the global carbon cycle is now recognized and evidence increasingly suggests that stream ecosystems disproportionately contribute to the carbon cycle. Understanding the dynamics and drivers of stream water partial pressure of ...

Assessment of the water resource in Tambarga (Burkina Faso) based on stable isotope analysis

Tabea Schutter

Assessment of available water is the basis that allows for sustainable management of the water resource. Special need concerns the assessment of groundwater resources, about which, often little is known. The present study aims to explore the water resource ...

Memory of past random wave conditions in submarine groundwater discharge

David Andrew Barry, Clare Robinson

Submarine groundwater discharge (SGD) is an integral part of the hydrological cycle and represents an important aspect of land-ocean interactions. We used a numerical model to simulate flow and salt transport in a nearshore groundwater aquifer under varyin ...

Influence of tides and waves on the fate of nutrients in a nearshore aquifer: Numerical simulations

David Andrew Barry, Clare Robinson

A numerical investigation is presented that demonstrates the influence of tides and waves on the transport and transformation of nutrients (NO3-; NH4+; PO43-) in a homogeneous unconfined nearshore aquifer and subsequent fluxes to the sea. Simulations of an ...

Calcarenite as a possible host rock for CO2 sequestration

Roman Makhnenko

Deep saline aquifers have a great potential for geologic carbon dioxide (CO2) sequestration and proper assessment of host and cap rock is needed to guarantee that the procedure is safe. Temperatures and pressures at which most of the possible host rocks ex ...

Assessment of bioremediation potential and monitoring of biological reductive dechlorination in sites contaminated with chlorinated ethenes

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski

Chlorinated ethenes (CEs), such as perchloroethene (PCE) and trichloroethene, are one of the most common classes of groundwater contaminants. In this project, the contaminant biodegradation capacities of two aquifers, presenting both dichloroethene (DCE) a ...
