Experimental evaluation of resistance of eroded bed in sediment laden open channel flow: Combined load transport case [PDF]

open access: yesEPJ Web of Conferences
A relation between the discharge and the flow depth in an open channel is quite sensitive to resistance (expressed by the friction coefficient) of the channel bottom.

Bed shear stress measurements over rough fixed and mobile sediment beds in swash flows [PDF]

open access: yes, 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 ...

Application of Satellite Sentinel-2 Images to Study Alternate Sandbars Movement at Lower Vistula River (Poland)

open access: yesRemote Sensing, 2021
The lower Vistula River was regulated in the years 1856–1878, at a distance of 718–939 km. The regulation plan did not take into consideration the large transport of the bed load. The channel was shaped using simplified geometry—too wide for the low flow

A Test Bed for Evaluating the Performance of IoT Networks [PDF]

open access: yes, 2020
The use of smaller, personal IoT networks has increased over the past several years. These devices demand a lot of resources but only have limited access. To establish and sustain a flexible network connection, 6LoWPAN with RPL protocol is commonly used.

Bed load transport by submerged jets [PDF]

open access: yesProceedings of the National Academy of Sciences, 1979
Some similarities are presented between the bed load transport of noncohesive grains in long rivers and at a local, jet-induced scour. Experiments are described in which a submerged two-dimensional slot nozzle, inclined downward, eroded a deep sand bed.

Probabilistic Modeling of Bed-Load Composition [PDF]

open access: yesJournal of Hydraulic Engineering, 2004
This paper proposes that the changes which occur in composition of the bed load during the transport of mixed-grain-size sediments are largely controlled by the distributions of critical entrainment shear stress for the various size fractions. This hypothesis is examined for a unimodal sediment mixture by calculating these distributions with a discrete

Experimental Study of Bed Shear Stress in Straight Channels Covered with Dunes of Different Sizes [PDF]

open access: yesعلوم آب و خاک, 2023
The formation of bed form in alluvial rivers due to sediment transport has a significant effect on the hydraulic parameters of the flow such as bed shear stress.

A Novel Efficient Method of Estimating Suspended‐To‐Total Sediment Load Fraction in Natural Rivers

open access: yesWater Resources Research, 2023
Sediment transport load monitoring is important in civil and environmental engineering fields. Monitoring the total load is difficult, especially because of the cost of the bed load transport measurement.
