WebMar 2, 2024 · capacity of curb-opening intakes decreases as the longitudinal gutter grade steepens. Consequently, the use of curb-opening intakes is recommended in sags and on grades less than 3%. Of course, they are bicycle safe as well. 3. Combination Intakes: Combination intakes provide the advantages of both curb opening and grate intakes. WebTo calculate the capacity of a Curb Inlet you must first calculate if the inlet is fully submerged or partially full. This will depend on the depth of flow at the curb. If the depth of flow at the curb opening inlet is such as to cause a partially full opening, a weir effect will develop and the following formula will apply.

WebThe Excel spreadsheet template shown below can be used to calculate the required size of a curb inlet for storm water drainage, based on specified information about the design storm water runoff rate, height of the curb opening, and the height of the storm water above the bottom of the opening.
