WebFred number is calculated by the following formula. Fr in the formula: Froude number, v: water flow velocity (m/s or ft/sn), g: gravitational acceleration (9.81 m/s 2 or 32.185 ft/s 2 ) and d is defined as the hydraulic depth (wetted cross-sectional area/width of … http://www.fsl.orst.edu/geowater/FX3/help/8_Hydraulic_Reference/Mannings_n_Tables.htm

WebBasis of Biofiltration Swale Design. 2. Basis of Biofiltration Swale Design . 2.1. Design Criteria . To perform as an effective Treatment BMP, the Biofiltration Swale must meet certain design criteria; the primary factors to be incorporated into the design are found in below Table 2-1. Table 2-1 Biofiltration Swale Design Criteria Webswales have higher hydraulic roughness and therefore require a larger area to convey flows compared to grass swales. trapped in the sediments.
