In the one-dimensional approach, the case of pollutant injection and river behaviour that do not depend on time is frequently considered. The integration of the fundamental differential equation is simplified and gives rise to very useful expressions for an overall assessment of water pollution. A further simplification is the case of nondispersive flow, which, applied to the BOD and DO interaction, results in the well-known Streeter and Phelps model, currently used for a first-glance evaluation of a river contamination caused by urban wastewater discharge.
