We describe the flow of sediment in river channels by replacing the complicated details of the turbulent water with probability arguments. Our major conclusions are that (1) sediment transport can be phrased in terms of the movements of individual sediment grains, (2) transport rates in river channels are inherently uncertain, and (3) sediment transport in rivers is directly analogous to a number of phenomena which we understand relatively well, such as molecules moving in air.

W.A.T.E.R. stands for Workshop on Advanced measurement Techniques and Experimental Research. It provides a structured approach for the learning and training platform to professionals with an experimental background in fluid mechanics. It offers an opportunity to learn about state-of-the-art instrumentation and measurement techniques and the latest developments in the field by partnering with academics, instrumentation manufacturers, and public sectors for sharing knowledge and good practices.
