Scuppers are the recommended method of deck drainage because they can reduce the problems of transporting a relatively large concentration of runoff in an area of generally limited right of way. Appendix 9c 8 ratio of frontal flow to total gutter flow.

Free with a google account. The inlet spacing spreadsheet xls 167 kb combines the procedures described in the wsdot hydraulics manual to calculate roadway runoff and inlet interception of a continuous curb and gutter run for a roadway. Triangle or multi triangle. The spread is usually referred to as ponded width t as shown in figure 10 10.

Spread for a given peak flow q value depends on the type of gutter section used. The sag worksheet xls 60 kb uses the procedure described in the wsdot hydraulics manual to locate inlets in a sag condition. Spread geometry and calculations a curb and gutter combination forms a triangular channel that can carry runoff without interrupting traffic. The spreadsheet calculates the minimum size of a vta to balance both the site s contributing water runoff and delivered nutrients.

Gutter spread should be checked to ensure a safe reasonable design. The larger of the two calculations must be used to balance both the annual runoff and delivered nutrients. Gutter and inlet equations anchor.
