You end up with a family of curves, which is the EQT table. Then, for a given headwater and tailwater elevation during the simulation, it looks both of those up on the EQT to find the flow. Some iteration may be required.

This can be confusing, as headwaters sound like the opposite of tailwaters, but in reality they aren't really related. The headwaters … chelsea gill psychic mediumWebcharacteristics and the tailwater. Minimum Performance: Minimum performance is assumed by analyzing both inlet and outlet control 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 chelsea gilligan heightWebThe first step is to determine tailwater depth. Since no obstructions are present downstream, flow depth in the stream is computed using Manning’s equation. For a design discharge of 480 cfs, tailwater depth is found to be 3.7 feet. ...
