Channel morphology and bed load pulses in braided, gravel-bed streams

Auteur :
ASHMORE, P.

Description :
Small-scale hydraulic laboratory models based on Froude modelling criteria were used to investigate : 1) the influence of gradient and discharge on the average cross-sectional geometry and channel pattern of braided streams| b) the temporal variability of braided stream morphology at constant gradient and discharge| c) the relationship between this temporal variability in morphology, the occurrence of bed-load pulses and the nature of bed-load transfer processes in gravel-bed braided streams.
