An experimental investigation on the water retention behaviour of a silty soil for the computation of the lateral earth thrust on a retaining wall

Lyesse Laloui, Alessio Ferrari, Gianluca Speranza

Retaining structures often interact with soils in unsaturated conditions and their performance is influenced by environmental actions. Currently, geotechnical analysis and design approaches mainly consider the soils either totally dry or totally saturated. ...

Modelling pumped-storage effects on thermal structure, ice cover and water quality of lakes and reservoirs in a changing climate

Ulrike Kobler

New renewable electricity is nowadays often generated by photovoltaics and wind. Yet, their intermittent nature calls for energy storage, which is today still provided to ~95% by pumped-storage (PS) hydropower plants. However, PS is known to affect abiotic ...

High amounts of antibiotic resistance genes and Class I integrons are disseminated in rivers of the Mekong delta (Viet Nam) from the effluents of intensive shrimp farms

Pierre Rossi, Florian Frédéric Vincent Breider, Emmanuelle Rohrbach

In the Mekong delta, intensive shrimp farming rely heavily on a wide panel of antibiotics (ABs) to prevent disease epidemics. Consequently, large amounts of antibiotic multi-resistant bacteria are emerging, threatening adjacent aquatic habitats used for ir ...

Velocities, Residence Times, Tracer Breakthroughs in a Vegetated Lysimeter: A Multitracer Experiment

Andrea Rinaldo, Michaël Bensimon, Paolo Benettin, Pierre Claude Jean Queloz

Flow velocities, residence times, and tracer breakthroughs at the lysimeter scale are affected by matrix properties and preferential flow. Despite their relevance to transport processes, however, the relative timing of preferential flow, and its link to tr ...

Effects of groundwater on desalinization in coastal reservoir and adjacent aquifer

David Andrew Barry, Jing Xu

Coastal reservoir provides the additional storage capacity of freshwater in coastal zone which greatly alleviate the water shortage in stressed areas, and the salinization of reservoir water degrade the utility of coastal reservoir. Salinization may result ...

Human domination of the global water cycle absent from depictions and perceptions

Camille Roland Marie Minaudo

Human water use, climate change and land conversion have created a water crisis for billions of individuals and many ecosystems worldwide. Global water stocks and fluxes are estimated empirically and with computer models, but this information is conveyed t ...

Safely Managed Hygiene: A Risk-Based Assessment of Handwashing Water Quality

Matthew Eric Verbyla, Timothy R. Julian

Sustainable Development Goal (SDG) Indicator 6.2.1 requires household handwashing facilities to have soap and water, but there are no guidelines for handwashing water quality. In contrast, drinking water quality guidelines are defined: water must be "free ...

Testing diﬀerent (e)DNA metabarcoding approaches to assess aquatic oligochaete diversity and the biological quality of sediments

Régis Lionel Vivien

Aquatic oligochaetes are important bioindicators of sediment quality in watercourses and lakes, but their morphological identiﬁcation to the species level is challenging and sometimes impossible. The use of DNA barcoding and metabarcoding could greatly fac ...

The utility of flow cytometry for potable reuse

Tamar Kohn, Krista Rule Wigginton, Brian Pecson

Protecting public health from pathogens is critical when treating wastewater to drinking water standards (i.e., planned water reuse). Viruses are a principal concern, yet real-time monitoring strategies do not currently measure virus removal through reuse ...

A Tale of Two Treatments: The Multiple Barrier Approach to Removing Chemical Contaminants During Potable Water Reuse

Urs von Gunten

In response to water scarcity and an increased recognition of the risks associated with the presence of chemical contaminants, environmental engineers have developed advanced water treatment systems that are capable of converting municipal wastewater efflu ...
