Gutter flow velocity. D flow depth at curb. Gutter capacity x reduction factor 2 84 x 0 86 2 44 l s therefore the proposed system is suitable. S x roadway cross slope. The zdgets very wide.

Both the velocity and flow rate in a gutter vary. Where q gutter flow rate n manning s coefficient s x roadway cross slope s longitudinal slope t flow width. Flow bypass must be equal or less than 0 1 cfs flowing across the travel lanes. The time of flow can be estimated by use of an average velocity obtained by integration of the manning s equation for the gutter section with respect to time.

The velocity in a gutter varies with the flow rate and the flow rate varies with the distance along the gutter i e. T flow width. When installing our high capacity gutters there is no requirement with the exception of the small half rounds to fix to falls. A depressing depth.
