WebInlet & Gutter Spreads In short, spreads are reported at both the face of the inlet and just upstream of the inlet. When an inlet is in a Sag condition, the spreads are the same and are determined by the depth (water surface … Web10.1 A roadway gutter has a longitudinal slope of 0.01 and a cross slope of 0.02. Using a Manning’s n of 0.016, find: a) the spread at a flow of 1.8 cfs b) the gutter flow at a spread of 8.2 ft. 10.2 A composite curb and gutter section is located on a roadway with a longitudinal slope of 0.01 and a cross slope of 0.02. The gutter width is 2 ...

WebTo compute gutter flow, the Manning equation is integrated for an increment of width across the section. The resulting equation in terms of cross slope and spread on the pavement is: Q = (K/n) S x 5/3 S1/2 T8/3 where K = 0.56; Q = flow rate, ft3/s; T = width of flow (spread), ft; S x = cross slope, ft/ft; S = longitudinal slope, ft/ft; blakedown pubWebThe gutter flow equation for calculating the higher gutter flows is as follows: log Q = K 0 + K 1 log S 0 + K 2 log y o + K 3 (CS) (Eq. 3-4) Where, Q = Gutter flow, cfs S 0 = Street grade, ft/ft Y 0 = Water depth in the gutter, feet CS = Curb split, feet K o , K 1 , K 2 , K 3 = Constant coefficients shown in Table 3-3 for different street widths: fracto cloudsWebDebris traps the water, causing the gutters to overflow.
