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. WebbThe design examples in this section use a simple ﬁrule of thumbﬂ approach, to estimate winter snowmelt for simplicity (Table I.1). The method assumes that winter snowmelt is influenced primarily by temperature, as represented by the average daily temperature for January. One half of the snow (adjusted for plowing and

WebbThere 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). Both of these methods are intended for use at the scale of a single drainage area. WebbThe model is based on the Simple Method (Schueler, 1987) for pollutant load calculations where impervious cover is used to estimate primary loads from various urban land uses. Loading for rural areas uses literature reported values and is primarily based on the area dedicated to row crops and forest and are based on literature values reported in Frink …
