On-field chemical profiling of volatile and odorous compounds in water pollution cases: toward a forensic in situ approach

Luiz Felippe De Alencastro, William Lacour

With 6% of Europe's freshwater resources, Switzerland is often considered the ‘water tower of Europe’. There are 57’600 farms and 750 wastewater treatment plants (WWTP) in the country. When manure or raw wastewater enters aquatic environment, accidently or ...

Coupled inverse modeling of a controlled irrigation experiment using multiple hydro-geophysical data

Gabriele Manoli, Damiano Pasetto, Matteo Rossi

Geophysical surveys can provide useful, albeit indirect, information on vadose zone processes. However, the ability to provide a quantitative description of the subsurface hydrological phenomena requires to fully integrate geophysical data into hydrologica ...

Chemical profiling of manure: toward source inference in environmental fraud cases?

Luiz Felippe De Alencastro, Nicolas Estoppey, Adrien Schopfer, William Lacour

With 6% of Europe's freshwater resources, Switzerland is often considered the ‘water tower of Europe’. Over 8 millions residents rely on more than 57’600 farms to provide meat, milk, or eggs, with 1.58 million cattle, 1.58 million swine or 9.39 million pou ...

Modeling of Hydrological Processes in Arid Agricultural Regions

David Andrew Barry

Understanding of hydrological processes, including consideration of interactions between vegetation growth and water transfer in the root zone, underpins efficient use of water resources in arid-zone agriculture. Water transfers take place in the soil-plan ...

An iterative particle filter approach for coupled hydro-geophysical inversion of a controlled infiltration experiment

Gabriele Manoli, Damiano Pasetto, Matteo Rossi

The modeling of unsaturated groundwater flow is affected by a high degree of uncertainty related to both measurement and model errors. Geophysical methods such as Electrical Resistivity Tomography (ERT) can provide useful indirect information on the hydrol ...

Comparison of stream temperature modeling approaches: the case of a high Alpine watershed

Michael Lehning, Wolf Hendrik Huwald, Francesco Comola, Aurélien Gallice

Stream temperature controls important aspects of the riverine habitat, such as the rate of spawning or death of many fish species, or the concentration of numerous dissolved substances. In the current context of accelerating climate change, the future evol ...

Modeling reactive transport of reclaimed water through large soil columns with different low-permeability layers

David Andrew Barry

The efficacy of different proportions of silt-loam/bentonite mixtures overlying a vadose zone in controlling solute leaching to groundwater was quantified. Laboratory experiments were carried out using three large soil columns, each packed with 200-cm-thic ...

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 ...

A review of the fate of micropollutants in wastewater treatment plants

David Andrew Barry, Christof Holliger, Luca Rossi, Jonas Margot

Municipal wastewaters are contaminated by a wide range of chemicals, from surfactants to heavy metals, including pharmaceutical residues, personal care products, various household chemicals, and biocides/pesticides. Their release into the environment, wher ...

Prolonged river water pollution due to variable-density flow and solute transport in the riverbed

David Andrew Barry

A laboratory experiment and numerical modeling were used to examine effects of density gradients on hyporheic flow and solute transport under the condition of a solute pulse input to a river with regular bed forms. Relatively low-density gradients due to a ...
