Mobilization Thresholds and Partial Transport of a Sand-Gravel Sediment
Twenty-eight coupled observations of flow, transport, and bed surface grain size distribution were made in a laboratory flume using a wide range of flows and a sediment with a very poorly sorted, bimodal grain size distribution. These observations permit the transport rates of individual size fractions to be scaled by the proportion of each size immediately available for transport on the bed su...
متن کاملCharacterization of bedload intermittency near the threshold of motion using a Lagrangian sediment transport model
At the smallest scales of sediment transport in rivers, the coherent structures of the turbulent boundary layer constitute the fundamental mechanisms of bedload transport, locally increasing the instantaneous hydrodynamic forces acting on sediment particles, and mobilizing them downstream. Near the critical threshold for initiating sediment motion, the interactions of the particles with these u...
متن کاملSediment transport-storage relations for degrading, gravel bed channels
[1] In a drainage network, sediment is transferred through a series of channel/valley segments (natural sediment storage reservoirs) that are distinguished from their neighbors by their particular capacity to store and transport sediment. We propose that the sediment transport capacity of each reservoir is a unique positive function of storage volume, which influences sediment mobility and avai...
متن کاملTransport of Gravel and Sediment Mixtures 3.1 Fluvial Phenomena Associated with Sediment Mixtures
When ASCE Manual No. 54, “Sedimentation Engineering,” was first published in 1975, the subject of the transport and sorting of heterogeneous sediments with wide grain size distributions was still in its infancy. This was particularly true in the case of bedload transport. The method of Einstein (1950) was one of the few available at the time capable of computing the entire grain size distributi...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
