WebThe capacity of a curb inlet in a sag depends on the water depth at the curb opening and the height of the curb opening. The inlet operates as a weir to depths equal to the curb opening height and as an orifice at depths greater than 1.4 times the opening height. Figure 10‑2 illustrates a generic example of a typical curb opening inlet. Curb inlets … ♦ Inlet Types; ♦ Curb Opening Inlets ; ...
