Three-Dimensional Turbulence Simulation of Flow in a V-Shaped Stepped Spillway
(American Society of Civil Engineers, 2017) -
Numerical Investigation of Circular Turbulent Jets in Shallow Water
(American Society of Civil Engineers, 2017)Knowledge of turbulent jets in shallow water depths is of utmost importance to adequately characterize municipal and industrial discharges. Propagation and dilution of such discharges are influenced by the presence of ... -
Resolved Simulation of a Granular-Fluid Flow with a Coupled SPH-DCDEM Model
(American Society of Civil Engineers, 2017) -
Two-Dimensional Large-Eddy Simulation of Density-Current Flow Propagating up a Slope
(American Society of Civil Engineers, 2017)A constant flow density current flowing on an inverse slope incline in the range of 1–6% slope is investigated using two-dimensional (2D) large-eddy simulations (LES). The dynamic Smagorinsky subgrid-scale model is used ... -
Geyser Formation by Release of Entrapped Air from Horizontal Pipe into Vertical Shaft
(American Society of Civil Engineers, 2017)Geysers are explosive eruptions of air-water mixture from manholes in drainage systems. When the design capacity of storm water drainage systems is exceeded during heavy rainfall, rapid inflows can lead to air-water ... -
Ring Diffuser to Dispense Antifoulants at Seawater Intakes
(American Society of Civil Engineers, 2017) -

Two-Dimensional Numerical Simulation of Bed-Load Transport of a Finite-Depth Sediment Layer: Applications to Channel Flushing
(American Society of Civil Engineers, 2017)Numerical modeling of bed-load transport in shallow flows, particularly oriented toward environmental flows, is an active field of research. Nevertheless, other possible applications exist. In particular, bed-load transport ... -

Extended Theory of Hydraulic Hysteresis in Open-Channel Flow
(American Society of Civil Engineers, 2017)The occurrence of hysteresis in a supercritical, open-channel flow approaching an obstacle has been recognized and investigated both experimentally and theoretically over the last few decades. However, the available theory ... -

Realistic Modeling of Leakage and Intrusion Flows through Leak Openings in Pipes
(American Society of Civil Engineers, 2017)The hydraulics of leakage and intrusion flows through leak openings in pipes is complicated by variations in the leak areas owing to changes in pressure. This paper argues that the pressure–area relationship can reasonably ... -
Experimental Study of the Eigenfrequency Shift Mechanism in a Blocked Pipe System
(American Society of Civil Engineers, 2017)Eigenfrequency shift in a pipe with a blockage is investigated experimentally. The experimental test rig consists of a reservoir-pipe-valve (RPV) system that contains a single partial blockage. Blockages with different ... -
Simple Modification of Manning-Strickler Formula for Large-Scale Roughness
(American Society of Civil Engineers, 2017)Large-scale roughness renders the flow resistance underestimated with the Manning-Strickler (MS) formula. This can be corrected simply by considering the roughness-induced flow constriction. Two modified MS formulas have ... -
Light Attenuation Model for Waters: Linear and Nonlinear Dependencies on Suspended Sediment
(American Society of Civil Engineers, 2017)Diffuse optical sensors estimate attenuation of natural light (solar irradiance) by measuring its vertical distribution in the water column, and the sensors are useful for estimating both suspended sediment concentration ... -
Erratum for “MacCormack-TVD Finite Difference Solution for Dam Break Hydraulics over Erodible Sediment Beds” by Chaojun Ouyang, Siming He, and Qiang Xu
(American Society of Civil Engineers, 2017) -
Quantitative Characterization of Streaky Structures in Open-Channel Flows
(American Society of Civil Engineers, 2017)Streaky structures have been reported in open-channel flows by various investigations in the inner and outer layer. Although the ubiquity of streaks is well recognized, it remains unclear how the streaky structures in the ... -
