Approximate analytical solutions for assessing the effects of unsaturated flow on seawater extent in thin unconfined coastal aquifers

David Andrew Barry, Zhaoyang Luo

This study develops approximate analytical solutions for seawater extent in unconfined coastal aquifers considering unsaturated flow, and assuming steady-state, sharp-interface conditions, for both constant flux (flux-controlled aquifers) and constant head ...

Impacts of climate change on Swiss alluvial aquifers - A quantitative forecast focused on natural and artificial groundwater recharge by surface water infiltration

Carl Love Mikael Råman Vinnå, Sebastiano Piccolroaz

The sensitivity of future groundwater recharge and temperature development was investigated for three alluvial aquifers in the urban agglomeration of the city of Basel, Switzerland. For selected climate projections groundwater recharge and the associated t ...

Semi-analytical solution of flow to a well in an unconfined-fractured aquifer system separated by an aquitard

David Andrew Barry

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 ...

Numerical methods for hydraulic fracture propagation: a review of recent trends

Brice Tanguy Alphonse Lecampion

Development of numerical methods for hydraulic fracture simulation has accelerated in the past two decades. Recent advances in hydraulic fracture modeling and simulation are driven by increased industry and research activity in oil and gas, a drive toward ...

Using Heat as a Tracer to Characterize Streambed Water Fluxes of the Brenta River (Italy)

Andrea Rinaldo

This work deals with the characterization of the spatial and temporal variability of water exchange fluxes from/to the Brenta river streambed (Veneto, Italy), critically important to regional water resources management. The aquifer system is structurally q ...

Effect of groundwater flow on the THM behavior of an energy pile

Lyesse Laloui, Fabrice Dupray, Mélanie Baehler

Bridges are one of the road structures that are most exposed to icing, a problem that is widely dealt with through salting, a technique that reduce the lifespan of the bridge. Seasonal storage of solar heat energy captured directly through the asphalt laye ...

Implementation of variably saturated flow into PHREEQC for the simulation of biogeochemical reactions in the vadose zone

David Andrew Barry, Laurin Wissmeier

A software tool for the simulation of one-dimensional unsaturated flow and solute transport together with biogeochemical reactions in the vadose zone was developed by integrating a numerical solution of Richards' equation into the geochemical modelling fra ...

Discussion of 'Diagnostic curve for confined aquifer parameters from early drawdowns' by Sushil K. Singh

David Andrew Barry, Laurin Wissmeier

The determination of aquifer parameters is fundamental to groundwater resources assessment. This important topic has received much attention in the literature over many years. Singh (2008) presented a method for determination of parameters for an ideal con ...

Effects of crab burrows on pore water flows in salt marshes

David Andrew Barry

Macro-pores such as crab burrows are found commonly distributed in salt marsh sediments. Their disturbance on the soil structure is likely to influence both pore water flows and solute transport in salt marshes; however, the effects of crab burrows are not ...

Geological heterogeneity in landslides : characterization and flow modelling

Significant progress has been made these last decades in the development of hydrogeological numerical flow modelling for describing the hydrodynamic behaviour of landslides. However, these new sophisticated methods are still very seldom used in the problem ...

Reactive transport in unsaturated Soil: Comprehensive modelling of the dynamic spatial and temporal mass balance of water and chemical components

David Andrew Barry, Laurin Wissmeier

By implementing the moisture-based form of Richards' equation into the geochemical modelling framework PHREEQC, a generic tool for the simulation of one-dimensional flow and solute transport in the vadose zone undergoing complex geochemical reactions was d ...
