Hello everyone, I have 3 questions and I'll greatly appreciate if you can help me out on this:
1. I would like know if you can create a channel model with different surface material on HEC-RAS software?
I have attached an image showing a section of the channel with a steel sheet pile on one side and a gravel bed.
2. What shall I do in order for the manning's coefficient be a factor in the model?
3. Do the manning's coefficient of the surface material in contact with the water flow affect the HEC-RAS MODEL? If it does, in what way? Is it the velocity? or the water depth of the HEC-RAS model output as shown on the profile?
Thanks
