Split flow modeling - roadside ditch and culvert
Split flow modeling - roadside ditch and culvert
(OP)
I'm trying to determine if there is a good way to use Hydrocad model split flow flow for the following described conditions.
Existing condition: There is a roadside ditch and a culvert crossing under the roadway. The roadside ditch contributes flows to the culvert and the ditch continues along the roadway past the culvert. I need to determine the amount of the split flows in each direction, through the culvert and through the ditch.
Proposed condition: Same as above, except a driveway and culvert is proposed just downstream of the existing culvert. I need to determine the amount of the split flows in each direction, through the existing culvert and through the proposed culvert.
Does someone have a good idea on how to model this?

You can also use a link to model a flow split according to a specified flow threshold and/or flow ratio. But using primary/secondary routing is generally preferred. For details see www.hydrocad.net/diversion.htm
