Weba. To determine the headwater depth of the concrete box culvert, we can use the following equation for inlet control: Q = ( 2 3) × C d × A × 2 g × h 3 2. where Q is the flow rate, Cd is the discharge coefficient (which can be assumed to be 0.6 for a square-edged inlet), A is the cross-sectional area of the culvert, g is the acceleration due ... Webtection requirements at culvert outlets. 9.3.5 HEADWATER CONSIDERATIONS The maximum headwater for the 100-year design flow will normally be 1.5 times the culvert diameter, or 1.5 times the culvert rise dimension for non-round shapes. Also, the headwater depth may be limited by the street overtopping requirements in Section 8. …
