Hydrodynamics and Length-Scale Distributions of a Random Cylinder Array
(American Society of Civil Engineers, 2025)In vegetated flows a reliable estimation of flow scales is crucial to understand and model mixing processes. This study presents velocity maps obtained using particle image velocimetry (PIV) within a cylinder array (diameters ... -
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 ... -
Flow Constrictions and Fish Behavior: Unraveling Undulatory Swimming Strategies in Accelerating Flow
(American Society of Civil Engineers, 2025)Section contractions in rivers often induce accelerated flows in nature, exerting substantial influence on the swimming behaviors of various fish species. This study focuses on the undulatory swimming strategies of fishes ... -
Experiments on Entrainment of Tailings into Suspension in an Annular Flume
(American Society of Civil Engineers, 2025)Sediment entrainment formulations developed for noncohesive materials have been widely applied to determine suspended loads in fluvial environments. Most relations were developed based on laboratory experiments and field ... -
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 ... -
Evaluating SWMM Modeling Performance for Rapid Flows on Tunnels with Geometric Discontinuities
(American Society of Civil Engineers, 2025)The EPA’s Storm Water Management Model (SWMM) has been applied across the globe for citywide stormwater modeling due to its robustness and versatility. Recent research indicated that SWMM, with proper setup, can be applied ... -
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 ... -
Engineered Step-Pool Sequences: Geometry, Failure Modes, and Stability
(American Society of Civil Engineers, 2025)Engineered step-pool sequences made from natural blocks to imitate the step-pool morphology of steep streams represent a nature-based alternative to concrete check dams. They potentially improve ecology and reduce construction ... -
Double Layer–Averaged Model of River Ice–Water Mixture Flow
(American Society of Civil Engineers, 2025)River ice–water mixture flows are commonly occurring natural phenomena that have the potential to cause serious hazards. To date, however, the interactive processes between ice and water have remained poorly understood. ... -
Critical Bed-Shear Stress of Mud–Sand Mixtures
(American Society of Civil Engineers, 2025)The critical bed-shear stress (cbs) for erosion of mud–sand bed mixtures was studied in laboratory and field conditions with currents, waves, and combined currents and waves. Three types of erosion were distinguished: ... -
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 ... -
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 ... -
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 ... -
Velocity Profiles in Gravel Beds Based on Refractive Index Matching Experiments
(American Society of Civil Engineers, 2025)The space-and time-averaged velocity profiles in gravel beds show some features that differentiates them from that established in smooth beds, but the obstruction posed by the gravel hampers the experimental measurements ... -
TVDLF Method to Simulate Two-Dimensional Flow through Large Hydrologic Systems with Wetlands and Hillslopes
(American Society of Civil Engineers, 2025)This paper presents a physical process-based integrated hydrologic model for multiyear simulations of surface and subsurface flow in large regional hydrologic systems with hillslopes, wetlands, natural, agricultural, and ... -
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
