WebbThe WTM uses the Simple Method (Schueler, 1987), a set of equations devised to calculate loads from urban stormwater runoff and non-urban land uses. The Simple Method estimates runoff pollutants loads on an annual basis (e.g. lb/yr) and is capable of estimating specific loads to individual land uses in a watershed. 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.

WebbModification of an empirical method that has been referred to by others as the Simple Method (Schueler, 1987) Utilizes annual runoff volume estimates and land use-based pollutant EMCs to predict: –average annual pollutant …
