Abstract: Pollutant transport within each phase of the hydrologic cycle, and through the various components of the physical system, is governed by the principle of conservation of mass. Deterministic mathematical models are derived from this unifying concept to represent the movement, decay, storage, and treatment of stormwater runoff pollutants and dry weather wastewater flows through the urban environment and ,the receiving body of water.
