How to set the reference concentration?

Hi, in the sediment transport model, when the cohesive settling flag is set to 0, so i want to how to set the reference setting velocity ? Thank you very much.

The setting of this parameter is dependent on your data. Typical values are from 1 to 10 m/day but can be as low as 0.1 m/day. If you don’t have data it is recommended you collect some. If that is not possible you will need to find some references with typical values for your system or equations to estimate the value.
