This handbook briefly describes the mechanisms causing oxygen depletion in polluted rivers. A description is given of a simple model (Streeter-Phelps) that can be used to make preliminary estimates of either river dissolved oxygen concentrations or the assimilative capacity of a river. Extensions of this simple model to allow for benthic oxygen demand, and aquatic plant photosynthesis and respiration are given. Procedures and data requirements for calibrating and verifying the models are described. The model equations can be solved using either the nomographs or the calculator and mini-computer programs supplied. Worked examples demonstrate their use
