    Thank you very much. I really need this knowledge.

      Thanks Isaac. Yeah, these parameters are really important.

    Just a quick question, if we have a tailing facility (non-Newtonian fluid) and a water dam (Newtonian fluid), then how these two can be modelled as in "Unsteady Flow Data", just one flow regime can be defined for the whole system, i.e. Newtonian or Non-Newtonian flow regime. Please correct me if I am wrong and if there is any solution to model these combination of flow regimes. Thanks

      This may be the most common question we get about 2D and I really need to do a video on it. In the standard fixed-bed NN tool, no, you only get one global Cv. But you can "hack" this by setting up a simple "mobile bed" sediment model (we even added simplifying tools like "concentration only" mode and a "deposition limiter" that will use the sediment engine to use the AD equation to route your debris flow into clear water...mix with the clear water, update the concentration, and feedback on the NN parameters. I really need to do a video on this...but i'm not sure when I'll get to it.

    Hello, I have a problem I am trying dam breach analys and I had an hdf error. It gives “Error in the time window
    Hdf error trying to close hdf output file hdf5 diag: Error detected in hdf5”

      If you have multiple dams in line, you could either set different breach times, or, better, set breach elevations for both of them, and after the first dam breaches, it will automatically fill the downstream reservoir and breach that dam.

    When we give the upstream hydrograph data, what is the time duration that we give for the hydrograph. Is it the same as breach formation time as calculated by different methods.
