Web1. The design flow velocity exiting the outlet at design capacity should not exceed the permissible velocity of receiving area. 2. Tailwater Depth : Tailwater is the water depth at the downstream end or outfall of the culvert. The depth of tailwater immediately below the outlet protection must be determined for the design capacity of the pipe. WebFlume design and selection ~ ~ Design is a two-step process. First, the control section shape is selected and its elevation set to allow the range of flows to be measured iiccurately without incurring excess submergence of the control section or undue increase in water levels upstream from the site. Once the control section is selected, the

Webfactor, above the peak design water elevation. Free Outlets . Free outlets are those outlets whose tailwater is equal to or lower than critical depth. For culverts having free outlets, lowering of the tailwater has no effect on the discharge or the backwater profile upstream of the tailwater. Frequency WebTo find the governing tailwater, H0, the critical depth in the culvert must first be determined. The critical depth is then used with the culvert size and compared to the specified tailwater as shown in Equation 6. Equation 6: …
