Headwater and tailwater

Tailwater refers to waters located immediately downstream from a hydraulic structure, such as a dam, spillway, bridge or culvert. Generally measured and reported as the average water depth downstream of a hydraulic structure, tailwater can vary based on the outlet from the structure as well as downstream influences that may restrict or advance the usual flow of water from the struct… http://www.fsl.orst.edu/geowater/FX3/help/4_Calculations/Culvert_Hydraulic_Calculations_Overview.htm

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.
