Improving the Measurement of Air–Water Flow Properties Using Remote Distance Sensing Technology
(American Society of Civil Engineers, 2025)In recent years, the research interest in the application of remote sensing technology to highly aerated flows has been increasing because this technology holds the ultimate promise to enable safe and accurate measurements ... -
A Nonorthogonal Elastoplastic Model for Overconsolidated Clay
(American Society of Civil Engineers, 2025)The constitutive model in geotechnical engineering plays a critical role, driving the need for ongoing research and improvement. In this study, by utilizing a single yield curve and only one hardening parameter, a nonorthogonal ... -
Bulk Flow Parameterization of Temporally Evolving Turbulent Stratified Open Channel Flow Subject to Radiative Heating
(American Society of Civil Engineers, 2025)The transient response of an initially neutral turbulent open channel subject to sudden stable stratification through radiative surface heating is investigated through direct numerical simulations. We find the convergence ... -
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 ... -
Variational Mechanics Formulation for Stream Meander Mechanics under Stable State End Conditions
(American Society of Civil Engineers, 2025)A mechanical analog formulation for distributed vibrating systems is used to derive a relationship between the fundamental meander frequency (cycling/s) and stream flow parameters mass per unit length and stream length. ... -
Capacity and Noncapacity Sediment Transport Characteristics in the Overtopping-Induced Dam-Breaching Process
(American Society of Civil Engineers, 2025)Although the applicability of physically based noncapacity sediment transport models has received increasingly wide recognition, debate still exists: it was reported that for overtopping-induced dam-breaching flows, the ... -
Flow-Sediment Interaction and Formation Mechanism of Sediment Longitudinal Streaky Structures in Rough Channel Flows
(American Society of Civil Engineers, 2025)Bed-load streaky structures are typical bed morphological features, yet its formation mechanism remains unclear. To fill this knowledge gap, flume experiments were conducted to quantitatively identify the characteristics ... -
Erosion and Deposition around Porous Engineered Log Jams: Flume Experiments and Improved Predictive Formulas
(American Society of Civil Engineers, 2025)Wood reintroduction into rivers, such as the construction of engineered log jams (ELJs), is increasingly popular in river restoration. ELJs are widely used because they mimic natural hydraulics and are relatively easy to ... -
Experimental Investigation of Leakage Flow Behavior in Pipes Subjected to Negative Pressures
(American Society of Civil Engineers, 2025)An in-depth understanding of leak behavior in water distribution systems is essential for ensuring the long-term reliability and resilience of critical infrastructure. While previous research has extensively explored leak ... -
Close-Range Photogrammetry Application to Monitor Levee Erosion in Case of Wave Overtopping
(American Society of Civil Engineers, 2025)Coastal and riverine levees are prone to wave and steady-flow overtopping, which can result in breaching and consequential flooding of the hinterland. Full-scale field experiments on a levee are a sound approach to ... -
Modeling Breach Evolution in Noncohesive Earthen Dams by Overtopping
(American Society of Civil Engineers, 2025)A two-dimensional, finite-difference numerical model is developed to simulate the breach evolution of noncohesive optimally compacted earthen dams. The main feature of the model is the inclusion of a source term in the ... -
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 ... -
3D Seismic Displacement Analysis of Pile-Reinforced Slopes in Anisotropic Layered Soils
(American Society of Civil Engineers, 2025)This study aims to investigate the effects of antislide piles and cohesion anisotropy on seismic displacements of three-dimensional (3D) layered slopes. A discrete mechanism generated by the point-to-point technique is ... -
Engineered Step-Pool Sequences: Geometry, Failure Modes, and Stability
