  • Weather Data Has Multiple Uses in Water Management

    According to their website, Central Utah Water Conservancy District (CUWCD) is "proud of its role in managing the water in its jurisdiction and using technology, intelligence and hard work to ensure the best possible balance for man and nature.” As part of this management and use of technology, Orion Weather Stations are located at Jordanelle Dam and Utah Lake Pumping Station with three ...

  • Fabrication of polysiloxane-modified polyurethane sponge as low-cost organics/water separation and selective absorption material

    Through sol-gel and dip-coating processes, commercial polyurethane sponge modified by polysiloxane was fabricated under low temperature (60 °C) and atmosphere. The contact angle of the obtained polysiloxane/polyurethane sponge is 145 ± 5°. Hence, the polysiloxane/polyurethane sponge could float on water and selectively absorb organics from the surface of the water, indicating simultaneous ...

  • Optimal operation of a multi-reservoir system for environmental water demand of a river-connected lake

    Dongting Lake, a large river-connected lake in the Yangtze River watershed, plays important roles in flood control, drought mitigation, and biodiversity conservation. Its ecosystem has recently been severely affected by upstream water resource development such as reservoir operations. In this study, an optimization model is developed for the operation of a multi-reservoir system, including the ...

  • Application of spatial Markov chains to the analysis of the temporal–spatial evolution of soil erosion

    Soil and water conservation in the Three Gorges Reservoir Area of China is important, and soil erosion is a significant issue. In the present study, spatial Markov chains were applied to explore the impacts of the regional context on soil erosion in the Xiangxi River watershed, and Thematic Mapper remote sensing data from 1999 and 2007 were employed. The results indicated that the observed ...

  • How to choose the most cost-effective methods for improving water quality

    Agricultural run-off can contain pesticides, sediment particles and nitrates and is a major threat to the health of the sea. Although there are policy frameworks to reduce run-off water, they often don’t clearly explain how to maximise benefits. A new study provides an economic framework that prioritises methods based on their cost-effectiveness, which could help policymakers to reduce the ...

  • Performance evaluation of a low-cost odour trap installed in waterless urinals

    Waterless urinals save precious fresh water normally used for flushing and reduce odour levels in restrooms. However, existing models of waterless urinals available on the market are expensive and maintenance costs of the odour traps of these urinals are also quite high. Experiments conducted using a low cost membrane-based waterless-urinal odour prevention trap available in India revealed a ...

  • Use of bauxite residue (red mud) as a low cost sorbent for sulfide removal in polluted water remediation

    Sulfide is an important pollutant in aqueous systems. Sulfide removal from polluted waters is required prior to discharge. Red mud (RM) is a solid waste of bauxite processing that is rich in reactive iron oxides and consequently has the potential to be used to remove sulfide from aqueous systems. A series of experiments was undertaken using raw and sintered RM to remove sulfide from waters. RM ...
