I am not able to figure out how to use charts to arrive at normal depth for open channel problems with a circular cross section.
I am able to use the chart in Appendix 19-C and table 19.3 in CERM to arrive at Q/Qfull, but I am kind of stuck in there. Should I be just using the mannings equations to calculate depth and would it be equal to normal depth....
If so, why isn't it working for flowing full and full half-full when I tried to derive the equations given in CERM, by modifying the mannings equations.
The basic question: how do I calculate normal depth for circular channels using the graph ?????????
Some one please answer my question. Thanks.
