  • Strategies for the electric regulation of pressure control valves

    In water distribution networks (WDNs), the classic pressure control valves (PCVs) are mechanical/hydraulic devices aimed at maintaining the target pressure just downstream or upstream of the PCV pipe, namely pressure reduction or sustaining valves. From a modelling standpoint, the major drawback of such local control is that classic PCVs may require target pressure varying over time with the ...

  • This polluted lake shows why we are all stakeholders when it comes to clean water

    When environmental protection gets short shrift, the price we pay can be staggering. When I visited Onondaga Lake in 1999 as part of research I did as a student at Cornell, there was no evidence the lake was once home to vibrant waterfront resorts. Yet, in the late 1800s and early 1900s, Onondaga was considered “ ...

  • Input-output model based ecological risk assessment for ecological risk management of watersheds: a case study in the Taihu Lake watershed, China

    To achieve advanced watershed ecological management, policy-makers have struggled to predict ecological impacts for a long time. As a process of ecosystem analysis, ecological risk assessment (ERA) has been widely adopted to analyse the possibility of adverse ecological effects. ERA has developed from considering only a few indicators in an area to multiple sources and receptors in large-scope ...

  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • Hydrometric network design using dual entropy multi-objective optimization in the Ottawa River Basin

    Water resources managers commonly rely on information collected by hydrometric networks without clear knowledge of their efficiency. Optimal water monitoring networks are still scarce especially in the Canadian context. Herein, a dual entropy multi-objective optimization (DEMO) method uses information theory to identify locations where the addition of a hydrometric station would optimally ...
