Morphological Bedload Transport In Gravel-Bed Braided Rivers, Sarah E. K. Peirce
Morphological Bedload Transport In Gravel-Bed Braided Rivers, Sarah E. K. Peirce
Electronic Thesis and Dissertation Repository
Gravel-bed braided rivers, defined by their multi-thread planform and dynamic morphology, are commonly found in proglacial mountainous areas. With little cohesive sediment and a lack of stabilizing vegetation, the dynamic morphology of these rivers is fundamentally the result of bedload transport processes but our understanding of the fundamental relationships between channel form and bedload processes remains incomplete. For example, the area of the bed actively transporting bedload, known as the active width, is strongly linked to bedload transport rates but these relationships have not been investigated systematically in braided rivers. This research builds on previous research to investigate the relationships …
