Mathematical models are derived from the principle of conservation of mass to represent the movement, decay, storage and treatment of stormwater runoff pollutants and dry weather wastewater flows through natural and engineered transport systems. Hourly urban runoff flows and pollutant mass loadings and concentrations are generated by continuous hydrologic and water quality computer simulation models. The transient response of stormwater storage/treatment systems to variable forcing functions of flow and concentration is determined for completely mixed systems of constant and variable volumes and for one-dimensional advective systems with dispersion.
