2 drainage areas w/culvert 1

[orshii]

How do I model 2 subareas linked by a culvert in HYDROCAD? (ex. Subarea A drains into Subarea B through a culvert that crosses a road).

 

[psmart]

Subcat A drains to pond A

Pond A is formed by the roadway impoundment, with a culvert outlet, and perhaps an overflow weir in case the road overtops. The pond outflow is routed to reach B.

Reach B represents the flow through subarea B. This may be a channel or overland flow. For details see

http://www.hydrocad.net/overland.htm

Sucat B drains into reach B -or- into another summation point downstream, depending on where the flows combine.
