Instead, these shapes use an HW/D interpolation table, defined by a chart in HDS-5, that can be used to determine headwater values at various values of Q/(AD^0.5 ... WebThe tailwater elevation will affect culvert capacity under outlet control conditions or may even drive a culvert into outlet control which may otherwise operate as inlet control. The storage capacity upstream of (behind) the culvert may need to be considered, especially if the culvert is to be altered in a way that may increase the headwater.

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.
WebJul 11, 2008 · We're designing a replacement culvert for an old 3-ft diameter culvert that collapsed. If we replace it with another 3-ft diameter pipe, the headwater will not overtop the road (not even close), but if we use the criteria that HW/D cannot exceed 1.5, then a 4-ft diameter pipe is needed.
