Predicting Hydraulic Jump Length on Rough Beds Using Data-Driven Models [PDF]
Journal of Rehabilitation in Civil Engineering, 2018 The hydraulic jump can be used for some purpose such as dissipating the flow energy in order to prevent bed erosion; aerating water and facilitating the mixing procedure of chemical that used for water purification.

PREDICTING MOVABLE BED ROUGHNESS IN COASTAL WATERS [PDF]
Coastal Engineering Proceedings, 2011 Accurately predicting movable bed roughness is essential to the analyses of transport processes, but when the bottom is rippled, as it commonly is in the coastal environment, characterizing the roughness is less straightforward than when the bottom is flat.

Impact of bed roughness and sediment permeability on mass exchange across sediment-water interface
Shui kexue jinzhan, 2020 The mass exchange process across sediment-water interface (SWI) plays an important role in contaminant migration and transformation in natural waters. The mass exchange across the SWI for rough bed depends on both bed roughness and sediment permeability.

Fluids, 2021 When using point measurement for environmental or sediment laden flows, there is well-recognised risk for not having aligned measurements that causes misinterpretation of the measured velocity data. In reality, these kinds of mismeasurement mainly happen

Hydrodynamics of steep streams with planar coarse-grained beds: Turbulence, flow resistance, and implications for sediment transport [PDF]
, 2017 The hydraulics of steep mountain streams differ from lower gradient rivers due to shallow and rough flows, energetic subsurface flow, and macro-scale form drag from immobile boulders and channel- and bed-forms.

Bed shear stress measurements over rough fixed and mobile sediment beds in swash flows [PDF]
, 2014 Direct measurements of bed shear stress have been conducted over rough fixed and mobile sediment beds in dambreak driven swash flows. The comparison between rough fixed and mobile bed results indicated the significant importance of grain borne shear ...

Air–water low patterns of hydraulic jumps on uniform beds macroroughness [PDF]
, 2017 Hydraulic jumps are characterized by strong flow turbulence, flow aeration, and three-dimensional flow motions. Whereas comprehensive research into hydraulic jumps on smooth bed has improved the understanding of flow aeration and turbulence, limited ...
