Quantitative definition of Shields criterion for incipient sediment motion被引量:1
《International Journal of Sediment Research》2024年第1期61-69,共9页Nian-Sheng Cheng Chengxiao Lu Yesheng Lu Maoxing Wei Lichan Zheng 
the National Natural Science Foundation of China(Grant Nos.52339005,51979242,and 52109103).
The Shields diagram has been widely used in the description of the threshold condition for incipient sediment motion.Because the current definition of the Shields criterion is generally subjective,the relevant data ar...

Numerical simulation of incipient particle motion
《International Journal of Sediment Research》2020年第1期1-14,共14页Ali Nasrollahi Ali Akbar Salehi Neyshabouri Goodarz Ahmadi Masoud Montazeri Namin 
A two-dimensional(2D)computational model for simulation of incipient sediment motion for noncohesive uniform and non-uniform particles on a horizontal bed was developed using the Discrete Element Method(DEM).The model...

Velocity profiles and incipient motion of frazil particles under ice cover被引量:9
《International Journal of Sediment Research》2010年第1期39-51,共13页Jueyi SUI Jun WANG Yun HE Faye KROL 
supported by the National Natural Science Foundation of China (Grant number:50979021)
A series of experiments for the incipient motion of frazil particles under ice cover have been carried out in laboratory under different flow and boundary conditions. Measurements on flow velocities across the measuri...

METAMODELLING APPROACH TO DESIGN THE ALLUVIAL CHANNELS AT INCIPIENT MOTION被引量:1
《International Journal of Sediment Research》2007年第3期218-227,共10页Achanta Ramakrishna RAO Bimlesh KUMAR Gopu SREENIVASULU 
The design of an alluvial channel for critical conditions requires information about four basic parameters, i.e., particle size d, water depth y, energy slope Sf and average velocity u. Most of the investigators use a...
