Characteristics of Propeller Jet Flow within Developing Scour Holes around an Open Quay
(American Society of Civil Engineers, 2018)By using the particle image velocimetry (PIV) technique, experimental results of the propeller jet flow field within a developing scour hole around an open quay are presented. The experiments were conducted with four toe ... -
Derivation and Validation of a Leakage Model for Longitudinal Slits in Polyethylene Pipes
(American Society of Civil Engineers, 2018)Although we do not understand the complex behavior of leaks in thick-walled plastic pipes, the ability to model them is essential to the assessment and mitigation of the real losses from drinking water–distribution systems. ... -
Erratum for “What Controls the Transition from Confined to Unconfined Flow? Analysis of Hydraulics in a Coastal River Delta” by Matthew Hiatt and Paola Passalacqua
(American Society of Civil Engineers, 2018) -
Detecting Thinner-Walled Pipe Sections Using a Spark Transient Pressure Wave Generator
(American Society of Civil Engineers, 2018)Research undertaken in the last two decades has demonstrated that hydraulic transient pressure waves, the phenomena behind water hammer, can be used as a tool for noninvasive and nondestructive condition assessment of long ... -

Design and Performance of a Radio Frequency Identification Scanning System for Sediment Tracking in a Purpose-Built Experimental Channel
(American Society of Civil Engineers, 2018)Sediment transport studies that use radio frequency identification (RFID) tracers are now common in hydraulic studies because of the information the technique provides on the spatial and temporal variability of sediment ... -
Review of <i>Hydraulicians in the USA 1800–2000: A Biographical Dictionary of Leaders in Hydraulic Engineering and Fluid Mechanics</i> by Willi H. Hager

Numerical Investigation of the Morphological Dynamics of a Step-and-Pool Riverbed Using DEM-MPS
(American Society of Civil Engineers, 2018)In mountain streams, riverbeds with a series of coarse gravel steps are common. The sequence flow pattern with a chute and pool is usually formed on series of steps, where a transition region from supercritical to subcritical ... -
Laboratory Calibration of Impact Plates for Measuring Gravel Bed Load Size and Mass
(American Society of Civil Engineers, 2017)Continuous monitoring of gravel transport in rivers is necessary for understanding the effect of dam removal on river systems. Impact plates, such as those deployed on the Elwha River in the state of Washington, are a ... -
Transitional Flow at Low-Head Ogee Spillway
(American Society of Civil Engineers, 2018)Low-head gated spillways provide controlled flow releases for defense against floods and a reliable supply of water for beneficial uses. In addition, a system of spillways in a large water resources system may be used for ... -
Design of a Throttled Surge Tank for Refurbishment by Increase of Installed Capacity at a High-Head Power Plant
(American Society of Civil Engineers, 2018)The Swiss confederation aims to phase out nuclear power production with its Energy Strategy 2050 program by increasing the renewable energy contribution to its overall energy generation. Hydroelectricity, which is the most ... -
One-Dimensional Particle Tracking with Streamline Preserving Junctions for Flows in Channel Networks
(American Society of Civil Engineers, 2018)A pseudo-three-dimensional particle tracking model of drifter paths has been developed to study the movement of scalars through a complex network of tidal channels and junctions. To better simulate dispersion caused by ... -
Internal Hydraulics of a Chlorine Jet Diffuser
(American Society of Civil Engineers, 2017)Multiport diffusers are used in many environmental applications to distribute a discharge flow uniformly through a number of jet nozzles into the same or another fluid. For example, a sewage diffuser can be designed to ... -
Optimizing the ASME Venturi Recovery Cone Angle to Minimize Head Loss
(American Society of Civil Engineers, 2018)Many flow-meter applications require accurate flow measurement (0.5% of actual flow or better), whereas other applications accept less-accurate flow measurements. Some applications attempt to minimize head loss, whereas a ... -
Erosion Velocity of Large Grains Subjected to a High Uniform Flow Velocity
(American Society of Civil Engineers, 2017)There is limited knowledge on the erosion rates of large grains. The available erosion models of granular material at large flow velocities are only validated up to a median particle diameter (d50) of 1.5 mm. To ... -
Applying Hypothesis of Self-Similarity for Flow-Resistance Law in Calabrian Gravel-Bed Rivers
(American Society of Civil Engineers, 2018)In this paper, the results of an investigation carried out to test the applicability of a flow-resistance law on gravel-bed rivers in southern Italy (fiumare) are reported. First, dimensional analysis and self-similarity ... -
Effects of Lateral and Vertical Constrictions on Flow in Rough Steep Channels with Bedload
(American Society of Civil Engineers, 2017)Two-phase flows occurring at flow constrictions such as bridges or open sediment check dams are complex, especially for steep rivers with bedload transport. Dangerous bedload deposition and backwater effects may occur in ... -
Estimated Splash and Training Wall Height Requirements for Stepped Chutes Applied to Embankment Dams
(American Society of Civil Engineers, 2017)Aging embankment dams are commonly plagued with insufficient spillway capacity. To provide increased spillway capacity, stepped chutes are frequently applied as an overtopping protection system for embankment dams. Stepped ... -
Reduced-Parameter Method for Maximum Entropy Analysis of Hydraulic Pipe Flow Networks
(American Society of Civil Engineers, 2018)A maximum entropy (MaxEnt) method is developed to predict flow rates or pressure gradients in hydraulic pipe networks without sufficient information to give a closed-form (deterministic) solution. This methodology substantially ...
