Ponding calculations
WebDec 31, 2024 · 1.08. The Area load is calculated as: Density/100 * Thickness = Area Dead load. For the example of the OSB board: 650 100 k g m 3 ∗ 0.02 m = 0.13 k N m 2. Now the sum of the dead load (value) can be applied to advanced 3D structural analysis models which can automatically calculate the line loads on the rafters. WebObtain the potential ponding area by multiplying this unit area by the available fence length. Using the calculated ponding area, calculate the ratio and enter the value in Figure SF-1 to determine the trapping efficiency. Perform an overtopping calculation using the slurry flow rate through the fence.

Webthat of the calculation of a index (see section 4.3.2). The rainfall hyetograph is integrated to calculate the total rainfall volume. Likewise, the runoff hydrograph is integrated to calculate the runoff volume. The infiltration volume is obtained by subtracting runoff volume from rainfall volume. The average infiltration rate is WebThe ratio on the right hand side of the Green-Ampt equation represents the hydraulic gradient. Since the ponding depth, H 0, and the pressure potential at the wetting front, H f, are treated as constants, the hydraulic gradient gets smaller as L f gets larger, i.e. as the wetting front moves farther away from the soil surface.
