WebOverland Flow/Runoff . Overland Flow is the transfer of surface water from an adjacent cell. It is calculated using the following formula in versions of the Natural System Model NSM 4.2 and below, or South Florida Water Management Model SFWMM 3.6 or less: Overland Flow Volume: In later version of these models the following formula is used: WebDec 28, 2024 · For a given surface area such as a roof or yard, multiply the area by the inches of rainfall and divide by 231 to obtain the runoff in gallons. The factor 231 comes from the fact that the volume of 1 gallon equals 231 cubic inches. When calculating roof runoff volume, you can use a direct runoff formula (in in 3) which calls for multiplying the ...
