Gutter Spread Spreadsheet

The larger of the two calculations must be used to balance both the annual runoff and delivered nutrients.

Gutter spread spreadsheet.

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. Spread geometry and calculations a curb and gutter combination forms a triangular channel that can carry runoff without interrupting traffic. Appendix 9c 9 velocity in triangular gutter sections. Minutes see hydraulics manual 2 5 3 runoff coefficients for rational method.

Create a new spreadsheet and edit it with others at the same time from your computer phone or tablet. Spread for a given peak flow q value depends on the type of gutter section used. Gutter and inlet equations anchor. Gutter spread should be checked to ensure a safe reasonable design.

The spreadsheet calculates the minimum size of a vta to balance both the site s contributing water runoff and delivered nutrients. Triangle or multi triangle. This spreadsheet calculates the spread width of flow gutter velocity and bypass flow for an inlet installation on a continuous run. Appendix 9c 5 flow characteristic curves straight cross slope 12 gutter appendix 9c 6 flow characteristic curve roll type gutter appendix 9c 7 flow in composite gutter sections.

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. See hydraulics manual 2 5 2 rainfall intensity inch hr see hydraulics manual 2 5 4. Free with a google account. The ponded width is a geometric function of the depth of the water y in the curb and gutter section.

However the use of scuppers should be evaluated for site specific concerns. Allowable width of flow flow spread or zd allowable 0 1 cfs maximum flow allowed to bypass last inlet qbp if flow is slow enough and gutter is flat spreadsheet allows more flow into inlet automatically done for you flow spreads these equations show the depth of flow as a function of gutter. The sag worksheet xls 60 kb uses the procedure described in the wsdot hydraulics manual to locate inlets in a sag condition.
