Dear Sir:
I test the normal depth BC with a simple straight long rectangular reach (B=4m, s=0.001, Q=12cms, n=0.015). But I found the depth calculated from RAS (h=1.19m) wasn’t equal to real normal depth. I don’t know why.
I also test another simile xsection reach and got the same result.
Would someone please help me? Thank you
