Effect of Groundwater on Landslide Triggering

Cornelia Sara Brönnimann

Landslides belong to the most important natural hazards in all mountainous regions. It is wellknown that water is one of the major triggers of landslides. Numerous landslide studies discuss different effects that water may have on slope stability: decreasi ...

Oxidative dissolution of biogenic uraninite in groundwater at Old Rifle, CO

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani

Reductive bioremediation is currently being explored as a possible strategy for uranium-contaminated aquifers such as the Old Rifle site (Colorado). The stability of U(IV) phases under oxidizing conditions is key to the performance of this procedure. An in ...

Experimental investigation of a breaking size segregation wave in a dry granular flow

Christophe Ancey, Nicolas Andreini, Gaël Epely Chauvin, Sébastien Bustamante

The objective of this paper is to provide evidence of the existence of breaking size-segregation waves in dry granular flows down inclined chutes. A flume was initially filled to a constant depth with a bimodal mixture of spherical particles that were reta ...

Design methodology accounting for the effects of porous medium heterogeneity on hydraulic residence time and biodegradation in horizontal subsurface flow constructed wetlands

David Andrew Barry, Luca Rossi, Alessandro Brovelli, Otoniel Carranza Diaz

Horizontal flow constructed wetlands are engineered systems capable of eliminating a wide range of pollutants from the aquatic environment. Nevertheless, poor hydrodynamic behavior is commonly found resulting in preferential pathways and variations in both ...

Composition, stability, and measurement of reduced uranium phases for groundwater bioremediation at Old Rifle, CO

Rizlan Bernier-Latmani

Reductive biostimulation is currently being explored as a possible remediation strategy for U-contaminated groundwater, and is being investigated at a field site in Rifle, CO, USA. The long-term stability of the resulting U(IV) phases is a key component of ...

Aeroelasticity at Reversed Flow Conditions – Part 1: Numerical and Experimental Investigations of a Compressor Cascade with Controlled Vibration

Peter Ott, Virginie Anne Chenaux

The prediction of flutter and forced response at normal flow conditions has become a standard procedure during the design of compressor airfoils. But at severe off-design conditions, the flow field becomes very complex, especially during the surge blow-dow ...

Geochemical processes controlling arsenic mobility in groundwater: A case study of arsenic mobilization and natural attenuation

Janet Gordon Hering

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 ...

Bacterial life in a stagnant PCE-contaminated aquifer

Christof Holliger, Pierre Rossi, Noam Shani

Chlorinated ethenes (CEs) represent a major environmental concern in most industrialized countries. These compounds, used as solvents and degreasing agents since the 1940s, have been released accidentally into the environment. Being recalcitrant to aerobic ...

Influence of physical factors and geochemical conditions on groundwater acidification during enhanced reductive dechlorination

David Andrew Barry, Alessandro Brovelli, Clare Robinson

Enhanced reductive dehalogenation is an attractive in-situ treatment technology for chlorinated contaminants. The process includes two acid-forming microbial reactions, that is, fermentation of an organic substrate to hydrogen and short chain fatty acids f ...
