Webb23 nov. 2024 · Based on these variables, an average annual runoff was calculated using the Simple Method ( Schueler, 1987 ). The allowable runoff load was then calculated by multiplying the average annual runoff by the chronic water quality standard for chloride (230 mg/L). Runoff coefficient 𝑅 𝑣 =0.05+0.9×𝐼𝐼𝑎𝑎 Where: I a = impervious fraction WebbThe Simple Method transforms precipitation depth into runoff volume using the following equation: (1) where: Runoff coefficient was based on a relationship developed by Schueler between impervious fraction and observed runoff. The impervious fraction was based on total impervious area versus total drainage area of the site: (2) where: Ia = devonshire anglican church bermuda

WebbAnnual surface runoff is determined using the Simple Method (Schueler, 1987), which relates runoff depth to annual precipitation and the fraction of the area in impervious cover. The Simple Method can be rearranged to estimate runoff from pervious and impervious areas separately. Webb16 juni 2009 · There are two primary methods that can be used to determine the volume of runoff from a given design storm: the Simple Method (Schueler, 1987) and the discrete SCS Curve Number Method (NRCS, 1986).
