Associations between inorganic arsenic in rice and groundwater arsenic in the Mekong Delta

Rizlan Bernier-Latmani, Matthew Charles Reid

There is growing concern regarding human dietary exposure to arsenic (As) via consumption of rice. The concentration and speciation of As in rice are highly variable, and models describing rice As speciation as a function of environmental covariates remain ...

Groundwater can have a critical role in sustaining the functioning of natural ecosystems during droughts, especially in dry and seasonally dry climates. However, the response to droughts of ecosystems embedded in urban areas is not well known. This study i ...

2020

The hierarchy of channel networks in landscapes displays features that are characteristic of nonequilibrium complex systems. Here we show that a sequence of increasingly complex ridge and valley networks is produced by a system of partial differential equa ...

Mitigation of impact of a major benzene spill into a river through flow control and in-situ activated carbon absorption

David Andrew Barry, Yue Yang

Benzene is a toxic contaminant and can harm many aquatic species and cause serious damages to the river eco-system, if released to rivers. In 2012, a major spill accident occurred on the Huaihe River in Eastern China with 3 tons of benzene released to the ...

2020

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 ...

A decade of progress and turning points in the understanding of bio-improved soils: A review

Lyesse Laloui, Dimitrios Terzis

Research and practice in the broader fields of civil and geotechnical engineering had long ignored the presence of living microorganisms in the subsurface and the way it impacts conventional practices. In the last 10 years, the term “microbial induced calc ...

Linear scaling of precipitation-driven soil erosion in laboratory flumes

David Andrew Barry, Seifeddine Jomaa

The proportionality between raindrop-driven soil erosion delivery and area of soil exposed to raindrops under a uniform precipitation rate was investigated in terms of individual size classes using laboratory flume experiments. In particular, we examined t ...

Soil surface morphology evolution under spatially non-uniform rainfall

David Andrew Barry, Andrea Rinaldo, Mohsen Cheraghi

We evaluated the applicability of a large-scale river network evolution model used to simulate morphological changes of a laboratory-scale landscape on which there were no visible rills. Previously, such models were used only at the landscape scale, or in ...

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 ...
