The wicked problem of suspended sediment profiles: a choice criterion

摘要

The study of suspended sediments in rivers is of very high importance for water quality management and it remains one of the most challenging subjects in hydraulic and environmental fields. Such a study requires a good understanding of the vertical distribution and velocity of suspended sediments.rnMore than one concentration profile can be found in the literature, and it is well known that they are highly sensitive to the parameters used to calculate them. Our present challenge is to make the optimal choice of concentration profile for given hydraulic hypotheses. This is not straightforward because of the underlying problem of the applicability of a profile built under given constraints on more general situations.
