Applying a Passive Vibration Detection Technique to Assess Bridge Pier Scour
(American Society of Civil Engineers, 2026)AbstractTraditional underwater measurements typically require equipment installation in the soil surrounding the bridge pier, which is high-cost and susceptible to flood-induced damage. To overcome these challenges, this ... -
An Enhanced Gray Wolf Optimizer and Its Application to Parameter Calibration in Open-Channel Flow
(American Society of Civil Engineers, 2026)AbstractParameter calibration is a key issue in open-channel flow models. Manning’s roughness coefficient, a comprehensive indicator of flow resistance, is highly variable and location-dependent. An optimization objective ... -
Assessing the Applicability of Boussinesq-Type Models for Steep Obstacle Flow Simulations
(American Society of Civil Engineers, 2026)AbstractBoussinesq-type models improve hydrodynamic simulations by capturing nonhydrostatic effects, offering advantages over nonlinear shallow-water equations. However, their performance in rapidly varying flows over steep ... -
Evaluation of the Near-Bed Velocity Decay Resulting from a Confined Bow Thruster Jet Using PIV Measurements
(American Society of Civil Engineers, 2026)AbstractObservations in the field suggest that the existing guidelines for bed protection design may lead to overly conservative protections at berthing structures of inland vessels. In this study, physical scale model ... -
New 1D Unsteady Friction Model for Turbulent Rough Pipe Flows Undergoing Slow to Intermediate Acceleration–Deceleration: Closely Packed Uniform Hemispheres

Effect of Stratification and Crossflow on the Dynamics of Bubble Plumes
(American Society of Civil Engineers, 2026)AbstractBubble plumes in stratified environments are very common in both environmental and industrial processes, with stratification influencing the mixing and material transport mechanisms. In this study, Eulerian–Lagrangian ... -
Air–Water Flows in a Deep Tunnel Downstream of a Dropshaft
(American Society of Civil Engineers, 2025)AbstractDropshafts of deep tunnel systems can entrain a large amount of air, and the resulting air–water interactions cause potential safety issues. In this study, the air–water flow characteristics along a tunnel under ... -
Riverbank Stabilization with Bioengineering: Failure Processes and Design Suggestions from a Scaled Physical Model
(American Society of Civil Engineers, 2026)AbstractSoil and water bioengineering structures (SWBEs) implemented for riverbank stabilization are often designed based on field feedback and expert knowledge. These structures are weaker in the years just after ... -
Robust Implicit Finite-Volume Method for Transient Mixed-Flow Modeling in Water-Conveyance Tunnels
(American Society of Civil Engineers, 2025)AbstractThe accurate simulation of transient mixed flow is a crucial concern for the design and management of water-conveyance tunnels. The free-surface and pressurized flows are characterized by significant disparity in ... -
