Culvert headwater calculations
WebAug 30, 2024 · 750.2.3.2 Outlet Control. Outlet control exists when the headwater elevation depends on the culvert barrel geometry or downstream conditions and the inlet is capable of conveying more flow than the barrel will accept. The control section is either at the downstream end of the barrel or further downstream. WebThe tailwater must be known or estimated prior to performing the culvert hydraulic calculations. There are various methods to estimate the tailwater at a culvert. One method is to estimate a downstream channel shape and use Manning's equation to calculate a …

WebFigure 13-8 shows the alternative culvert openings and resulting road profiles. Therefore, the twin 4-foot by 13-foot box culvert is the better choice because it results in a headwater elevation only 0.3 foot higher than existing and requires a significantly smaller roadway embankment than would the higher culvert.
