Toward a Universal Energy Approach to Estimate Rate of Scour
(American Society of Civil Engineers, 2025)The paper presents a semiempirical method to estimate the rate of scour of earth materials, supplementing existing empirical and semiempirical methods that only quantify maximum scour depth. The premise is that the rate ... -
Strongly Coupled 2D and 3D Shallow Water Models: Theory and Verification
(American Society of Civil Engineers, 2025)We introduce a monolithic/strong, interfacial coupling formulation between two-dimensional (2D) and three-dimensional (3D) shallow water (SW) and transport models. This coupling becomes necessary in regions such as estuaries ... -
Radial Mixing in Steady and Accelerating Pipe Flows
(American Society of Civil Engineers, 2024)Understanding solute transport in pipe flows is essential for ensuring consistent water quality throughout the entire drinking water supply network. This study used four planar laser-induced fluorescence (PLIF) units for ... -
Proportional-Integral Control of Pressure-Reducing Valves Using Control Lyapunov Functions
(American Society of Civil Engineers, 2024)This work presents nonlinear and linear controls ensuring the global stability of a pressure-reducing valve. The global property using both nonlinear and linear controls is very important to guarantee stability even though ... -
Prediction of Geyser Occurrences in Covered Manholes of Urban Stormwater Systems
(American Society of Civil Engineers, 2025)Storm geysers are air–water eruptions from stormwater manholes during intense rainfalls, which raise public safety concerns. They arise from entrapped air release in stormwater tunnels as flow transitions from open to ... -
Physics-Informed Neural Networks for Steady-State Weir Flows Using the Serre–Green–Naghdi Equations
(American Society of Civil Engineers, 2025)This paper presents physics-informed neural networks (PINNs) to approximate the Serre–Green–Naghdi equations (SGNEs) that model steady-state weir flows. Four PINNs are proposed to solve the forward problem and three types ... -
Physics-Informed Neural Network Approach for Solving the One-Dimensional Unsteady Shallow-Water Equations in Riverine Systems
(American Society of Civil Engineers, 2025)In recent years, many researchers have used machine learning approaches to bridge the relationship between big data and physics in the practical engineering field. However, the widely used machine learning models are highly ... -
Turbulent Friction in Canonical Flows: State of the Science and Future Outlook
(American Society of Civil Engineers, 2024)Quantifying turbulent friction holds significant importance, not only for understanding the fundamental flow physics but also for enriching system performance across a wide range of engineering applications. This vision ... -
Experimental Tests of Lateral Bedload Transport Induced by a Yawed Submerged Vane Array in Open-Channel Flows
(American Society of Civil Engineers, 2024)This work proposes the use of an array of yawed porous vanes to control the lateral bedload transport by locally steering bedform migration and maximize the amount of sediments redirected toward a potential sediment ... -
Delineating Flood-Induced Sediment Scour in Bridge-Contracted Channels: Processes, Patterns, and Scour Depth under Various Scour Regimes
(American Society of Civil Engineers, 2024)Flooding water in extreme hydrometeorological events may be significantly contracted by bridge abutments and superstructures, leading to severe sediment scour and threatening structure stability. A series of large-scale ... -
Impact of Bed Scour on the Length and Stability of Rock Vanes and Bendway Weirs
(American Society of Civil Engineers, 2024)Consequences are presented from flume experiments regarding bed scour at rock vanes and bendway weirs constructed of loose rock placed on sand bed channels. The experiments involved three flow discharges adjusted to replicate ... -
Modeling Interactions between Hydraulic Transients and Inline Air Pockets in Water Pipelines: Dynamic Behavior and Energy Dissipation
(American Society of Civil Engineers, 2024)The existing one-dimensional model is inadequate in predicting the dynamic interactions between hydraulic transients and inline air pockets in water pipelines, leading to underestimated pressure dissipation in the modeling ... -
Exploring Hydraulic Impacts of Downstream Water Levels on the Drainage Capacity of a Stormwater Pipe
(American Society of Civil Engineers, 2024)This paper designs and builds a stormwater pipe-river/channel experimental system at the first attempt to observe hydraulic dynamics between pipe flow and downstream water levels under different steady state conditions. ... -
Acoustic Doppler Velocimetry in Transient Free-Surface Flows: Field and Laboratory Experience with Bores and Surges
