Orifice Spillway Aerator: Hydraulic Design
- Abstract: V. V. Bhosekar, V. Jothiprakash, and P. B. Deolalikar Orifice spillways are in vogue for the dams in the hilly regions where the spillway has to serve the dual function of flood disposal and flushing of sediment through the reservoir. Deep-seated orifice spillways are subjected to cavitation damage as the cavitation index drops below the critical cavit ... [J. Hydraul.

Predicting Longitudinal Dispersion Coefficient in Natural Streams Using M5[prime] Model Tree
- Abstract: Amir Etemad-Shahidi and Milad Taghipour The longitudinal dispersion coefficient is a key parameter in determining the distribution of pollution concentration, especially in temporally time-varying source cases after full cross-sectional mixing has occurred. Several studies have been performed to present simple formulas to predict it. Howe ... [J. Hydraul. Eng. doi:10.1061/(ASCE)HY.1943-7900.0000550] published Fri Jun 8, 2012.

SPH Modeling of Shallow Flow with Open Boundaries for Practical Flood Simulation
- Abstract: R. Vacondio, B. D. Rogers, P. K. Stansby et al. A smoothed particle hydrodynamics (SPH) numerical model for shallow water equations (SWEs) is presented for simulating flood inundation owing to rapidly varying flow, such as dam breaks, tsunamis, and levee breaches. Important theoretical and numerical developments have recently been made, and the m ... [J. Hydraul. Eng. doi:10.1061/(ASCE)HY.1943-7900.0000543] published Fri Jun 8, 2012.

Two-Phase Simulation of Wave-Induced Tunnel Scour beneath Marine Pipelines
- Abstract: Mohammad Hossein Kazeminezhad, Abbas Yeganeh-Bakhtiary, Amir Etemad-Shahidi et al. An Eulerian two-phase flow model was presented and employed to investigate wave-induced tunnel scour beneath marine pipelines. The model is based on the Euler-Euler coupled governing equations for the fluid and sediment phases, i.e., time-averaged continuity and momentum equations were solved for bo ... [J. Hydraul.

Hydraulic Analysis of Suspended Sediment Removal from Storm Water in a Standard Sump
- Abstract: Adam K. Howard, Omid Mohseni, John S. Gulliver et al. Standard sumps (manholes) are common features of urban storm water collection systems, and there are anecdotes suggesting that standard sumps can improve storm water quality. However, no data on the effectiveness of sumps as treatment devices for suspended sediment removal and the associated require ... [J. Hydraul.

Physical and Numerical Modeling of the Entrainment by a High-Concentration Mud Suspension
- Abstract: A. W. Bruens, J. C. Winterwerp, and C. Kranenburg This paper presents the results of a physical and numerical model study on the entrainment by a high-concentration, cohesive sediment suspension. This turbulent, near-bed suspension is referred to as a concentrated benthic suspension (CBS). In the current configuration, the CBS entrains low-concentr ... [J. Hydraul.

The Influence of Surface Tension on Air-Water Flows
- Abstract: I. W. M. Pothof, A. D. Schuit, and F. H. L. R. Clemens Stricter environmental regulations have led to new wastewater treatment plants and a centralisation of existing wastewater treatment plants. Therefore, pressurised wastewater mains have become an indispensable link between the collection systems and the treatment plants. In urban areas in particular ...

On-Line Monitoring of Steel-Lined Pressure Shafts by Using Pressure Transient Signals under Normal Operation Conditions
- Abstract: F. E. Hachem and A. J. Schleiss The local deterioration of the mechanical properties of steel-lined pressure shafts and tunnels induces a decrease of the celerity and an increase of the energy attenuation of water-hammer wave. This deterioration may arise from the weakening of the backfill concrete and the surrounding rock mass wh ...

Simplified Approach for the Optimal Sizing of Throttled Air Chambers
- Abstract: Giuseppe De Martino and Nicola Fontana Among water hammer damping devices, air chambers are often used in pumping plants to reduce pressure surges to acceptable values. The chamber is more effective if a throttling device is used, resulting in a reduction of the required volume. Using the rigid column theory (incompressible flow) and the ...

Laboratory experiments of sediment entrainment were carried out in a flume for different flow configurations with particle image velocimetry (PIV) used to measure the flow velocity. The experiments were done in low submergence condition. Measurements revealed that the vertical distribution of stream ...
