I’m having a problem when I’m running the SIAM. It always says “Error Solving Yang for sediment size 0.707…. mm for reach upstream and profile 1” and the list of sediment sizes goes on. I know that there is a limit for the sediment size for Yang’s equation to be effective, but even though the sediment is between the range, it still says the same thing stated above. How can I fix this? thank you.
