- Abstract:
- Braided rivers are associated with repeated separation and joining of individual river channels. In order to understand how river channels braid, it is necessary to understand the fluid dynamics associated with this process. Research to date has focused upon junctions within braided river systems. However, more recent investigations have shown that separation or bifurcation is a crucial, perhaps more important, aspect of the braiding process. In this research we will explore the morphological characteristics (e.g. planform shape, asymmetry) of bifurcations and undertake both scaled laboratory modelling and computational numerical modelling to understand: the flow processes present within bifurcations; the influence of upstream controls on bifurcation flow processes: and the downstream impacts of bifurcation flow structures. This will allow a physically-based understanding of the controls on bifurcation flow processes and an explanation of current observations of how bifurcations evolve (e.g. in terms of developing symmetry and asymmetry). The findings will also be interpreted in relation to system-scale models of bifurcation behaviour.
