Fhwa inlet types
WebMethods and procedures are given for the hydraulic design of storm drainage systems. Design methods are presented for evaluating rainfall and runoff magnitude, pavement drainage, gutter flow, inlet design, median and roadside ditch flow, structure design, and storm drain piping. WebThe inlet models were designed as modular clip-in parts (wingwalls, center walls, and top plates) that could be changed easily to test various configurations. Two sets of model …

WebLaboratory tests sponsored by the FHWA have established two general types of culvert flow: Flow with inlet control Flow with outlet control. Nomographs have been prepared for use in the determination of culvert headwater for the appropriate control. Under inlet control, the headwater HWI is directly related to the cross-sectional area of the ... WebThe FHWA has standardized the manner by which culverts are examined and designed.

WebBoth forms of the equations are used in the HEC-RAS software, depending on the type of culvert. The nomographs in the FHWA report are considered to be accurate to within about 10 percent in determining the required inlet control headwater [FHWA, 1985]. The nomographs were computed assuming a culvert slope of 0.02 feet per foot (2 percent). http://onlinemanuals.txdot.gov/txdotmanuals/hyd/gutter_and_inlet_equations.htm
