Characterizing Aquifer Heterogeneity Using Bacterial and Bacteriophage Tracers

Pierre Rossi

Gravel aquifers act as important potable water sources in central western Europe, yet they are subject to numerous contamination pressures. Compositional and textural heterogeneity makes protection zone delineation around groundwater supplies in these unit ...

Evaluation of geochemical and hydrogeological processes by geochemical modeling in an area affected by evaporite karstification

The Ebro Valley in the outskirts of Zaragoza (NE Spain) is severely affected by evaporite karstification, leading to multiple problems related to subsidence and sinkhole formation. In this work, a combination of inverse (mixing + mass-balance) and forward ...

Long-term in-situ oxidation of biogenic uraninite in an alluvial aquifer: impact of dissolved oxygen and calcium

Rizlan Bernier-Latmani, Daniel Scott Alessi, Elena Suvorova Buffat, Harish Veeramani

Oxidative dissolution controls uranium release to (sub)oxic pore waters from biogenic uraninite produced by natural or engineered processes, such as bioremediation Laboratory studies show that uraninite dissolution is profoundly influenced by dissolved oxy ...

Analytical approximation for the recession of a sloping aquifer

David Andrew Barry, Marc Parlange

An approximation is obtained for the recession of a sloping aquifer. The analytical approximation can provide a useful tool to analyze data and obtain physical properties of the aquifer. In contrast to the case of a horizontal aquifer, when plotting the ti ...

Speciation and reactivity of uranium products formed during in situ bioremediation in a shallow alluvial aquifer

Rizlan Bernier-Latmani, Daniel Scott Alessi, Elena Suvorova Buffat

In this study, we report the results of in situ U(VI) bioreduction experiments at the Integrated Field Research Challenge site in Rifle, Colorado, USA. Columns filled with sediments were deployed into a groundwater well at the site and, after a period of c ...

The importance of hydraulic groundwater theory in catchment hydrology: The legacy of Wilfried Brutsaert and Jean-Yves Parlange

Alexis Berne

Based on a literature overview, this paper summarizes the impact and legacy of the contributions of Wilfried Brutsaert and Jean-Yves Parlange (Cornell University) with respect to the current state-of-the-art understanding in hydraulic groundwater theory. F ...

Evaporation from a shallow water table: Diurnal dynamics of water and heat at the surface of drying sand

Marc Parlange, Ivan Lunati, Chad Higgins

Accurate estimates of water losses by evaporation from shallow water tables are important for hydrological, agricultural, and climatic purposes. An experiment was conducted in a weighing lysimeter to characterize the diurnal dynamics of evaporation under n ...
