Analytical Groundwater–Erosion Model
(American Society of Civil Engineers, 2026)AbstractThe failure mechanism of piping, which involves the formation of pipes and their subsequent growth from downstream to upstream, often occurs under river dikes and earth dams. When the water level is high, this ... -
Analytical Solution of Quasi-Two-Dimensional Method for Unsteady Transient Pressurized Pipe Flows in the Time Domain
(American Society of Civil Engineers, 2025)AbstractIn investigating the unsteady transient pressurized pipe flows, including the water hammer (WH) phenomenon, accurate prediction of the pressure head history, mean velocity, and wall shear stress is crucial. In this ... -
Laboratory Observations of Frazil Ice Accumulation during Freeze-Up Stage
(American Society of Civil Engineers, 2025)AbstractA series of experiments was conducted using a laboratory flume within the University of Ottawa cold room to measure accumulation of frazil ice and ice jamming for open channel flows over various bed materials and ... -
Failure Patterns of Protective Flexible Mattresses on a Riverbank under Water Flow Scouring. II: Multistage Identification and Quantification
(American Society of Civil Engineers, 2026)AbstractAnalyzing and quantifying failure patterns of bank protective flexible mattresses are of the paramount importance in bank stability assessments and early collapse warnings. Based on the experimental results presented ... -
Numerical Simulation of the Relationship between Sediment Movement States on Rippled Bed Surfaces and Flow Structures
(American Society of Civil Engineers, 2026)AbstractThe interactions between sediment transport and turbulent flow structures are closely related; however, quantitative research is lacking. In this study, large eddy simulation is combined with the discrete-element ... -
Santa María and the First Bridge Scour Formulas
(American Society of Civil Engineers, 2025)Forum papers are thought-provoking opinion pieces or essays founded in fact, sometimes containing speculation, on a civil engineering topic of general interest and relevance to the readership of the journal. The views ... -
Effect of Bimodal Gravel Size Distribution on the Clean-Out Depth of Sand
(American Society of Civil Engineers, 2025)AbstractThe clogging of the gravel surface layer in gravel-bedded channels with finer sediment (<2 mm) is a common problem that negatively impacts streambed habitat quality. Most existing measurements of surface-layer ... -
Influence of Length-to-Width Ratio on Flow and Turbulence in the Wake of Piles with Elongated Cross-Sections
(American Society of Civil Engineers, 2025)AbstractElongated circular bridge piers are commonly used in hydraulic structures. Their interaction with the incident flow for varying length-to-width ratios, especially in the wake region, has not been comprehensively ... -
Discussion of “Mixed Velocity Scale for Predicting Bed-Material Sediment Discharges in Open Channel Flows”
(American Society of Civil Engineers, 2025) -
Analyzing the Emptying Process of a Large-Scale Pipeline with Three-Dimensional CFD Simulations
(American Society of Civil Engineers, 2025)AbstractUnderstanding the physical mechanisms of air–water flow in pipelines is essential for optimizing the design of pressurized fluid transport systems. A three-dimensional (3D) computational fluid dynamics (CFD) model ... -
Estimation of Discharge Coefficients for Free-Flowing Compound Weirs with Upstream Horizontal Flow Contraction
(American Society of Civil Engineers, 2025)AbstractCompound weirs have been used as adjustable structures to divert flow, for example, through river branches at the river bifurcations. For this purpose, a wide variety of weir configurations can be used including ... -
Laboratory Application of Real-Time LiDAR Technology for Assessing Breach Morphology during the Failure of Earth Dams and Fluvial Dikes
(American Society of Civil Engineers, 2025)AbstractEmbankments such as fluvial dikes or dams may fail due to breaching caused by overtopping or internal erosion. The mechanisms associated with the temporal evolution of embankment breaching are still not fully ... -
Experimental Investigation of the Hydrodynamic Behavior of a Flexible Line of Floating Modules to Contain Wood Logs Upstream of Hydroelectric Plants
(American Society of Civil Engineers, 2025)AbstractThe containment of wood logs and debris floating in the river upstream of Brazil’s Santo Antônio hydroelectric plant is a major issue for the plant’s operation. Log booms are floating structures assembled in the ... -
Characterization and Modeling of Harmful Algal Blooms: A Review
(American Society of Civil Engineers, 2025)AbstractHarmful algal bloom (HAB) occurrences are continuing to increase globally, with often far-reaching environmental, economic, and social consequences. Given the detrimental effects due to their growing presence in ... -
Energy Dissipation and Turbulent Characteristics of Flow Regimes Downstream of a Submerged Weir at Multiple Slopes
(American Society of Civil Engineers, 2025)AbstractThe design of hydraulic structures typically does not account for the higher water levels that can occur during unforeseen floods. This research study places a strong emphasis on conducting experiments to characterize ... -
Effect of Vanes in a Channel Transition on Reducing Turbulence and Boundary Shear Stress
(American Society of Civil Engineers, 2025)AbstractErosion of open channels has been a common and costly problem. It occurs when the free-surface flow in a channel exerts turbulent boundary shear stress (BSS) on the channel bed or sidewalls exceeds a certain ... -
Friction Factors for Flow through Cracks in Concrete Hydraulic Structures
(American Society of Civil Engineers, 2025)AbstractFlow through cracks in a variety of concrete structures can be problematic for water resources infrastructure. Design of drainage systems to collect and remove such flow requires estimating flow rates through cracks. ... -
Self-Aerated Hydraulic Jumps in Closed Circular Pipe: Intrusive Measurement of Internal Air–Water Flow Properties
