This phenomenon is complex and consequently a theoretical study can only be performed in simplified cases. Therefore, this Topical Issue on Sediment Transport Mechanics has been designed and organized around the idea that the grain scale can provide insight over the whole phenomenological chain resulting from the interactions among the three phases (fluid, rough boundaries, and moving sediments).

A. BAGNOLD INTRODUCTION During the present century innumerable flume experi­ ments have been done, and a multitude of theories have been published in attempts to relate the rate of sediment transport by a stream of water to the strength of the water flow.

Sediments in waterborne transport are usually classified as fine if the grain size is less than 63 :m, based on the Wentworth Scale division between sands and silts. For transport purposes sediments are principally characterized by their size, by constituent composition, and by cohesion. The sediment transport capacity is calculated using the transport potential method. (This is akin to the procedure outlined in the section on depth-integrated sampling, above.)
