Sediment transport is a geological process involved in the morphological evolution of the surface of the earth. Fundamental and applied aspects concerning this process are of interest for human societies. Sediment transport can be triggered by a moving fluid on cohesive or noncohesive sediments produced by the weathering of landmasses. The transport of sediments is influenced by complex interactions between physical features of particles and properties of flow. For instance, the mechanics of flow close to the bed of a river or a sea is implied in the threshold of motion of sediments and in their migration downstream. Processes involved in sediment transport and the estimation of transport rates in rivers and coastal environments constitute major scientific issues. The development of new analytical devices in the recent years offers new perspectives for the evaluation of sediment transport rates by combining direct or indirect measurements performed on the field and semiempirical equations. These tools are promising for understanding of the physical processes involved in sediment transport.
