  • Generation of daily naturalized flow at ungaged control points

    The development of daily naturalized flow in the water rights analysis package (WRAP) model at ungaged stations has difficulties because of low daily flow measurement at gaged stations, low available monthly naturalized flow, and budget constraints. This study proposes a procedure for developing daily naturalized flow at ungaged stations. The soil and water assessment tool (SWAT) model was ...

  • Hydrologic and biogeochemical controls of river subsurface solutes under agriculturally enhanced ground water flow

    Received for publication October 17, 2008. The relative influences of hydrologic processes and biogeochemistry on the transport and retention of minor solutes were compared in the riverbed of the lower Merced River (California, USA). The subsurface of this reach receives ground water discharge and surface water infiltration due to an altered hydraulic setting resulting from agricultural ...

  • Hydrologic and biogeochemical controls of river subsurface solutes under agriculturally enhanced ground water flow

    The relative influences of hydrologic processes and biogeochemistry on the transport and retention of minor solutes were compared in the riverbed of the lower Merced River (California, USA). The subsurface of this reach receives ground water discharge and surface water infiltration due to an altered hydraulic setting resulting from agricultural irrigation. Filtered ground water samples were ...

  • Langham Industrial Controls Flow and Pressure Adaptor for Monitoring Customer Water Supply Performance

    The success of our manifold Pressure Adaptor has led to the development of our most recent product, the Manifold Flow and Pressure Adaptor. Langham Industrial Controls Ltd has recognised that there is a need within the water industry to measure both flow and pressure at the boundary box. This can now be achieved by connecting a manifold meter and dual channel data logger to the Langham ...

  • Modeled Flow Duration Variations, Pollutant Discharges, and Costs for Different Stormwater Controls

    ABSTRACTRunoff volume and pollutant discharges increase with development, with associated detrimental receiving water effects. These increases can be partially controlled by installing stormwater control practices, such as wet detention pond at outfalls, using conservation design controls such as grass swales and bioretention devices, and by improved development practices that reduce the amounts ...

  • Wireless Pakscan controls the flow at Nevada gold mine - Case Study

    A gold mine in Nevada USA has been able to take advantage of wireless Pakscan digital control for newly installed IQ intelligent electric valve actuators on the water filtration plant. The Newmont underground mine utilises Geotube® dewatering technology to separate sediment from both ground and extraction process water. The filter systems, which are installed above ground, are fabricated from ...

  • The impact of stormwater source-control strategies on the (low) flow regime of urban catchments

    Stormwater management strategies increasingly recognise the need to emulate the pre-development flow regime, in addition to reducing pollutant concentrations and loads. However, it is unclear whether current design approaches for stormwater source-control techniques are effective in restoring the whole flow regime, and in particular low flows, towards their pre-development levels. We therefore ...

  • The impact of water flow configuration on crystallisation in LiBr/H2O absorption water heater

    Lithium Bromide (LiBr) strong solution entering the absorber tends to crystallise when the absorber temperature is increased for a fixed evaporating pressure. This is considered the key technical barrier for the development of a LiBr absorption heat pump water heater. There are several approaches to avoid the crystallisation problem, such as chemical crystallisation inhibitors, heat and mass ...

  • 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. ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • Seasonal water quality vs. flow relationships in a small regulated stream

    The relationship of a water quality constituent with respect to flow measured at a stream monitoring station can give valuable information about the watershed and in-stream processes about the constituent in question. Seasonal dependency patterns often reveal relationships which would be unnoticed if all data are treated together. The aim of this study is to examine water quality constituent ...
