  • Uncertainty in design flood profiles derived by hydraulic modelling

    The scientific literature has widely shown that hydraulic modelling is affected by many sources of uncertainty (e.g. model structure, input data, model parameters). However, when hydraulic models are used for engineering purposes (e.g. flood defense design), there is still a tendency to make a deterministic use of them. More specifically, the prediction of flood design profiles is often based ...

  • Measuring the Dispersion Coefficient with Acoustic Doppler Current Profilers

    Abstract: A method is evaluated for estimating the longitudinal dispersion coefficient K from velocities and bathymetry measured with an acoustic Doppler current profiler #1;ADCP. If shear dispersion controls the mixing, the dispersion coefficient can be estimated from measurements of velocity and depth in a cross section. The dispersion coefficient has typically been measured by costly and ...

  • Shredder for solid and thick-walled profiles and pipes

    NEUE HERBOLD Maschinen- und Anlagenbau GmbH, Sinsheim, (www.neue-herbold.com), extends their machinery range by a new 4-shaft shredder with force feeding system. The 4-shaft shredder type HZR 1300/4 is able to size-reduce solid chunks and start-up lumps, as well as thick-walled profiles and pipes up to a diameter of 1200 mm x 1200 mm and up to a length of 6000 mm. The size ...

  • Numerical analysis of hydraulic jumps using OpenFOAM

    The present paper deals with a hydraulic jump study, characterization and numerical modeling. Hydraulic jumps constitute a common phenomenon in the hydraulics of open channels that increases the shear stress on streambeds, so promoting their erosion. A three-dimensional computational fluid dynamics model is proposed to analyze hydraulic jumps in horizontal smooth rectangular prismatic open-air ...

  • Integrating GIS and Hydraulic Modelling in Urban and Rural Applications

    Overview In the UK, numerical Hydraulic Modelling of the urban environment, water networks and rivers plays a vital role in providing the UK Water Industry with solutions for protecting the environment, meeting UK Government and European Regulations, meeting OPEX and CAPEX business targets, and improving the efficiency of Water Companies in managing their assets. Similarly, the UK water ...

  • Application of modified Manning formula in the determination of vertical profile velocity in natural rivers

    Seldom studied before, the vertical profile velocity is indicative of the flood process and nutrient transportation process. In this paper, a substitution of cross section hydraulic radius with vertical depth was made to the Manning formula, which was then applied in the vertical profile velocity determination. Simultaneously, the determination accuracy and its relationship with hydraulic ...

  • Effect of urban waste compost application on soil near-saturated hydraulic conductivity

    Received for publication February 22, 2008. Compost application tends to increase soil fertility and is likely to modify soil hydrodynamic properties by acting on soil structural porosity. Two composts, a municipal solid waste compost (MSW) and a co-compost of green wastes and sewage sludge (SGW), have been applied every other year for 6 yr to cultivated plots located on a silt loam soil in the ...

  • Hydraulic modeling - Bethel Park Municipal Authority - Case Study

    Treatment plant hydraulics is often overlooked as one of the most important aspects of treatment plant design, especially in plant upgrade scenarios where retrofitting new equipment or processes into the existing treatment train will create additional hydraulic restrictions.  Many existing plants already have a minimal amount of head available for passing peak flows through the system, which ...
