These load estimates can be obtained by separating the calculations of runoff concentrations from the calculations of runoff volumes and using the mean event concentrations of limited runoff events to approximate the mean event concentrations of whole runoff events. Computations of mean concentrations and loads of toxic contaminants in urban runoff can be accomplished by means of a newly developed model referred to as the PMSQ model. Applications of the model are demonstrated on available runoff quality data.http://creativecommons.org/licenses/by/4.0/Journal of Waterway112093-115 Tsanis Giannis Τσανης Γιαννης Brissette, Pascal Elsevier
