Waterborne virus transport and the associated risks in a large lake

Tamar Kohn, Timothy R. Julian, Xavier Fernandez Cassi, Chaojie Li

Waterborne enteric viruses in lakes, especially at recreational water sites, may have a negative impact on human health. However, their fate and transport in lakes are poorly understood. In this study, we propose a coupled water quality and quantitative mi ...

Impact of sodium gluconate on white cement-slag systems with Na2SO4

Karen Scrivener, Berta Mota Gassó

Sodium gluconate has been shown to compensate the impact of alkalis on the long term strength development of cement pastes. This work studies the impact of sodium gluconate combined with Na2SO4 on the microstructural development of white cement-slag system ...

Chemical composition, nutrient-balancing and biological treatment of hand washing greywater

Odile Marie Clotilde Hervás de Nalda-Larivé

On-site biological hand washing water treatment can improve global access to safe hand washing water, but requires a thorough understanding of the chemical composition of the water to be treated, and an effective treatment strategy. This study first presen ...

Decomposing the Bulk Electrical Conductivity of Streamflow To Recover Individual Solute Concentrations at High Frequency

Paolo Benettin

The ability to evaluate stream hydrochemistry is often constrained by the capacity to sample streamwater at an adequate frequency. While technology is no longer a limiting factor, costs and sample management can still be a barrier to high-resolution water ...

Young runoff fractions control streamwater age and solute concentration dynamics

Andrea Rinaldo, Paolo Benettin

We introduce a new representation of coupled solute and water age dynamics at the catchment scale, which shows how the contributions of young runoff waters can be directly referenced to observed water quality patterns. The methodology stems from recent tre ...

Dynamic water allocation policies improve the global efficiency of storage systems

Paolo Perona, Amin Niayifar

Water impoundment by dams strongly affects the river natural flow regime, its attributes and the related ecosystem biodiversity. Fostering the sustainability of water uses e.g., hydropower systems thus implies searching for innovative operational policies ...

Transit times-the link between hydrology and water quality at the catchment scale

Paolo Benettin

In spite of trying to understand processes in the same spatial domain, the catchment hydrology and water quality scientific communities are relatively disconnected and so are their respective models. This is emphasized by an inadequate representation of tr ...

Linking water age and solute dynamics in streamflow at the Hubbard Brook Experimental Forest, NH, USA

Andrea Rinaldo, Paolo Benettin

We combine experimental and modeling results from a headwater catchment at the Hubbard Brook Experimental Forest (HBEF), New Hampshire, USA, to explore the link between stream solute dynamics and water age. A theoretical framework based on water age dynami ...

The economic impact of climate driven changes in water availability in Switzerland

Marc Vielle, Camille Gonseth, Anne-Kathrin Faust

The broad objective of this study is to estimate the economic impact of changes in water availability due to climate change in Switzerland with a 2050 time horizon. To do so, the sectoral structure of the computable general equilibrium model GEMINI-E3 is b ...

Water Saving and Energy Reduction through Pressure Management in Urban Water Distribution Networks

Koen Blanckaert

Water shortages and climate change are worldwide issues. Reduction in water leakage in distribution networks as well as the associated energy saving and environmental impacts have recently received increased attention by scientists and water industries. Pr ...

Influence of geometry shape factor on trapping and flushing efficiencies

Anton Schleiss, Sameh Ahmad Kantoush

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped a ...

Ab initio simulation of particle momentum distributions in high-pressure water

Michele Ceriotti

Applying pressure to water reduces the average oxygen-oxygen distance, and facilitates the delocalisation of protons along the hydrogen bond. This pressure-induced delocalisation is further enhanced by the quantum nature of hydrogen nuclei, which is very s ...

Evolution of the global virtual water trade network

Andrea Rinaldo

Global freshwater resources are under increasing pressure from economic development, population growth, and climate change. The international trade of water-intensive products (e.g., agricultural commodities) or virtual water trade has been suggested as a ...

Temporal dynamics of blue and green virtual water trade networks

Andrea Rinaldo

Global food security increasingly relies on the trade of food commodities. Freshwater resources are essential to agricultural production and are thus embodied in the trade of food commodities, referred to as "virtual water trade." Agricultural production p ...

Base case process development for energy efficiency improvement, application to a Kraft pulping mill. Part II: Benchmarking analysis

François Maréchal

A new procedure for benchmarking analysis has been developed to evaluate the energy efficiency of a chemical process. Benchmarking is performed to identify process inefficiencies before developing energy enhancement measures. The new procedure combines typ ...

Semi-empirical model for channel bed evolution due to lateral discharge withdrawal

Anton Schleiss, Burkhard Rosier

Side weirs and overtopable levees are widely used to increase flood routing along a channel or river. The lateral loss of water reduces the sediment transport capacity leading to the formation of a local sediment deposit close to the overflow. Since the ex ...

One-Dimensional Numerical Modelling Of Mobile Bed Evolution In A Flume With A Side Weir

Anton Schleiss, Burkhard Rosier

Side weirs are widely used to control flow processes along a channel or river. The lateral loss of water reduces the sediment transport capacity in the main-channel leading to local sediment deposition near the overflow. The design discharge to be diverted ...
