  • Free-surface flow simulations for discharge-based operation of hydraulic structure gates

    We combine non-hydrostatic flow simulations of the free surface with a discharge model based on elementary gate flow equations for decision support in the operation of hydraulic structure gates. A water level-based gate control used in most of today's general practice does not take into account the fact that gate operation scenarios producing similar total discharged volumes and similar ...

  • Oil-Water Separator with New Coalescing Media Handles High Load Stormwater at HydroElectric Powerplant to Yield Zero Oil Discharge

    Background Removal of oil from water before the water is discharged into a river or other body of water is an important environmental goal. In order to accomplish this, a major hydropower producer in the southern United States contracted with HydroQuip, Inc.* for the supply of a state of the art oil/water separator. The power plant had several goals, but the most important was that in ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • Treatment of Arsenic Contaminated Industrial Wastewaters

    Arsenic in industrial wastewater effluents is attracting greater regulatory attention. Depending on factors such as total maximum daily loads (TMDLs), the National Pollutant Discharge Elimination System (NPDES) discharge permit levels for arsenic may even be less than the drinking water standard of 10 µg/L. One of the industries affected by stringent arsenic discharge limits is coal-fired power ...

  • Managerial response to sea level rise in the tidal estuaries of the Indian Sundarbans: a geomorphological approach

    Tidal estuaries constrained by embankments in the Sundarbans have failed to respond to a >1 m sea level rise over the past 100 years since their construction. This paper shows that this has led to a disequilibrium morphology leading to channel erosion that has undermined embankments, causing mass failure, breaching and subsequent flooding during surge events. Predicted future sea level ...

  • Excavation, Retrieval, and Off-Site Disposal

    Introduction: Contaminated material is removed and transported to permitted off-site treatment and/or disposal facilities. Some pretreatment of the contaminated media usually is required in order to meet land disposal restrictions. Confined disposal facilities (CDFs) are engineered structure enclosed by dikes and designed to retain dredged materials. A CDF may have a large cell for ...

  • Water quality is key to the success of Cardiff Bay

    Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in April 1987. This article will examine the role that water quality has played in the remarkable transformation that has taken place in Cardiff and explain how monitoring technology has developed to the stage whereby any person, anywhere in the world, can view ...
