http://onlinemanuals.txdot.gov/txdotmanuals/hyd/improved_inlets.htm WebInlet control flow generally occurs in steep, smooth culverts. The culvert will flow partially full under supercritical conditions as shown in Fig. 6.12A and Fig. 6.12B. However, if the downstream end of the culvert is submerged, a hydraulic jump can form, after which the culvert would flow full as in Fig. 6.12C or Fig. 6.12D. childs computer desks

WebTapered Inlets for Pipe Culverts John L. French , M.ASCE PDF Tools Share Abstract The performance of pipe culverts on steep slopes with tapered inlets is, in general, sensitive to the presence of air-carrying vortices over the inlet. Under such conditions, an area of operation is defined. WebThe limitations to the culvert calculations are that no upstream or downstream cross sections are used. So the energy gradeline is calculated assuming a quiescent, level pool above the inlet and a quiescent stilling basin at the outlet. Inlet Controlled Use this method when the culvert outflow is controlled by a high pool elevation in the ...
