EISSN:1943-7900|ISSN:0733-94290|Disc:The Journal of Hydraulic Engineering accepts original contributions that describe the analysis and solutions of problems in hydraulic engineering. Technical Notes may present a problem, without solution, of common interest. Topics range from flows in closed conduits to free-surface flows (canals, rivers, lakes, and estuaries) to environmental fluid dynamics. Topics include transport processes involving fluids (multiphase flows) such as sediment and contaminant transport, and heat and gas transfers. Emphasis is placed on the presentation of concepts, methods, techniques, and results that advance knowledge and/or are suitable for general application in the hydraulic engineering profession|Priority:12|Publisher:American Society of Civil Engineers|

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 ... -
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 ... -
Impact of Flood Loading and Initial Conditions on Transient Seepage Analyses
(American Society of Civil Engineers, 2025)Levee seepage analysis for design often uses steady-state analyses, which produce conservative results. Transient seepage analyses are appealing because they can account for time-dependent flood loadings. Uncoupled transient ... -
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 ... -
