Mid-channel bar growth and its relationship to local flow strength and direction

Auteur :
ASHWORTH, P.J.

Description :
This paper provides data on the spatial and temporal pattern of surface velocity as mid-channel bar growth is initiated downstream of a fixed junction scour in a generic scale flume model. These flume data and interpretations are compared to descriptions in the literature of the braiding process. A new model for mid-channel bar growth is presented which helps explain the long-term development of the confluence-diffluence unit.
