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. http://uon.sdsu.edu/onlineculvert.php ealing hmo licence fees https://e-healthcaresystems.com
