Flow modelling to estimate suspended sediment travel times for two Canadian Deltas
The approximate travel times for suspended sediment transport through two multi-channel networks are estimated using flow modelling. The focus is on the movement of high sediment concentrations that travel rapidly downstream. Since suspended sediment transport through river confluences and bifurcati...

The approximate travel times for suspended sediment transport through two multi-channel networks are estimated using flow modelling.

Calibration of the flow model is discussed, with an emphasis on the incorporation of cross-section data, that are not referenced to a datum, using a continuous water surface profile.
