Considerations In Estimating Tailwater Elevations

Webcontrol and using the highest headwater. The culvert may operate more efficiently at times (more flow for a given headwater level), but it will not operate at a lower level of performance than calculated. 8.6.3 Inlet Control For inlet control, the control section is at the upstream end of the barrel (the inlet). The flow Webdiscrete discharge, and corresponding tailwater and headwater elevations. In areas of flat, low-lying terrain, some culverts may serve to hydraulically equalize the water surface elevations at each end. Culverts which are influenced by the tailwater elevation are said to be flowing under “Outlet Control” as previously described. ching young shopping center
