Investigation on Flow Resistance of Large‐Scale Channels With Unmanaged Spontaneous Vegetation

Hydrological Processes, Volume 40, Issue 5, May 2026.
The hydraulic measurements of two surveys (November 1995 and June 1996) by Flippin‐Dudley et al. were used. A theoretical flow resistance equation was assessed for a large‐scale vegetated channel. The analysis demonstrated that the theoretical flow resistance equation allows an accurate estimate of the Darcy–Weisbach friction factor.

Machine Learning for Dynamic Pressure Coefficient Prediction in Vertical Water Jets

Fluids
Vertical water jets present significant challenges for hydraulic structures due to their potential to cause erosion and structural damage. This study aimed to predict the dimensionless pressure coefficient (Cp) of vertical water jets by examining the ...

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

Hydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

The prediction of wake wash in the towing tank [PDF]

, 2008
The wash or ship-generated waves from high speed craft has become a common subject in research and development of marine transportation. Since some time now the wake wash of high speed craft has become a problem in particular on inland or confined ...

Joint Angular Excursions and Angular Range Utilization During Stance‐Phase Locomotion in Terrestrial Mammals: A Comparative Morphofunctional Data Set

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 4, Page 361-376, May 2026.
This study quantifies stance‐phase joint angular excursions and angular utilization (AUI%) during walking in 182 terrestrial mammal species. Across mammals, total limb excursion during stance (TAE) decreases with increasing body mass, whereas AUI% remains broadly conserved, indicating similar proportional use of summed joint excursions to generate net ...

Investigation of heat transfer enhancement inside developing gravity-driven films along a vertical permeable plate subject to nonuniform suction

Advances in Mechanical Engineering, 2015
Flow and heat transfer through the boundary layers of a falling liquid film on a vertical permeable plate subject to nonuniform suction flow are analyzed in this work. The continuity, momentum, and energy equations are transformed to nonsimilar equations

On the Multiple Steady Flow States in Spindle Shaped Geometry of Bridge Foundations [PDF]

Journal of Applied Fluid Mechanics
Flow hysteresis in a channel with a supercritical flow in the vicinity of a spindle-shaped bridge foundation (SSBF) with a change in flow rate has been investigated in a laboratory for the first time.

Software to Support Remote Sensing of River Discharge Based on Critical Flow Theory

River Research and Applications, Volume 42, Issue 4, Page 915-928, May 2026.
ABSTRACT Water resource management requires accurate observations of streamflow but standard field methods for measuring river discharge ( Q ) can be costly and hazardous for equipment and personnel. Remote sensing has become a viable alternative, but many image‐based techniques require field data for calibration, and depth and velocity can seldom be ...

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Numerical Study of Flow Characteristics on Landward Levee Slopes Under Overtopping at Different Froude Numbers

Sci
Most levees are composed of earthen materials, making their structural stability vulnerable under flood conditions, especially in the case of overtopping. This study aims to analyze the relationship between the channel Froude number and the flow behavior
