On December 25, Vice President of WASER, Prof. Weiming Wu from the Clarkson University, visited the International Research and Training Center on Erosion and Sedimentation (IRTCES). During his visit, he was invited to give a seminar on the "Advances in Sediment Transport Dynamics – Sediment Entrainment" at the IRTCES. Experts and graduate students from the IRTCES and China Institute of Water Resources and Hydropower Research (IWHR) attended this seminar.

Prof. Qingbin Pan, Deputy Director of the IRTCES, hosted the seminar. He expressed his gratitude to Prof. Weiming Wu for his long-term support for the development of WASER and for joining hands with IWHR to promote international cooperation and talent cultivation in the field of sedimentation research.

During the seminar, Prof. Wu systematically sorted out the classical theory of sediment incipient and its development. He introduced the threshold conditions for individual particle entrainment, evaluated the applicability of different sediment entrainment formulas, summarized the different modified expressions of Shields Diagram, analyzed the incipient motion of nonuniform sediments with hiding and exposure correction factors, and explored the effects of exposure height, bed roughness, particle shape, shallow submergence, turbulence, and impulse duration on incipient motion.
Following his presentation, Prof. Wu had an energetic discussion with the attendees about how engineering-oriented sediment research can promote basic sediment theory research, and the differences in the sediment research between China and other countries.
