Planform Change And Bedload Transport In Braiding Rivers, Lara Middleton
Planform Change And Bedload Transport In Braiding Rivers, Lara Middleton
Electronic Thesis and Dissertation Repository
Proglacial gravel-bed braided rivers have a dynamic planform composed of multiple unstable channels and ephemeral bars. The planform position is seen to change during high flows as the position of channels and bars is seen to change. These changes are produced as pulses of bedload transport are mobilized and transported downstream, causing an observable change in the river planform and morphology. While it is known that bedload transport, morphological change and planform change in a braided river are inter-related the relationships have not been quantified. The first component of this research was to build on previous results by re-analyzing daily …
