Open channel with zero slope
Open channel with zero slope
(OP)
Any suggestions on how to model open channel flow in a channel with zero slope and a drain located about halfway along its length? It is a unifomrly shaped asphalt channel.

then I would use Manning's but each calculation will only be good for a short distance as the 'normal' level will increase to create at false slope the farther you get from the drain. eg there will be a slope in the hgl and egl but it changes as you get away from the drain.

As msquared48 has said a backwater calculation is probably the way to go, however, you will have to consider how the flow is actually getting to the drain.
Looking at the smaller picture 0% slope= 0 conveyance....
You will probably have to consider a more broader approach considering the flow paths u/s of your area of interest, is there enough momentum u/s to actually carry the flow to your area of interest???? A RAS model may be the way to go...
Hope this helps.
