Designers typically work with a single peak flow value and design a closed storm drain system for full flow conditions. In a modeling situation, particularly with continuous models, a wide range of flows may occur. A conduit may operate in open channel, full

www.oregon.govwhen it enters a closed conduit such as a culvert or storm drain. The velocities in the segments of the drainage path with openchannel or pipe flow are determined by Manning's - equation. Once the velocity is known, the travel time for the segment is calculated by dividing the segment length by the velocity. The procedure is similar to the ...
