The Streeter–Phelps equation is used in the study of water pollution as a water quality modelling tool. The model describes how dissolved oxygen (DO) decreases in a river or stream along a certain distance by degradation of biochemical oxygen demand (BOD). The equation was derived by H. W. Streeter, a … See more The Streeter–Phelps equation determines the relation between the dissolved oxygen concentration and the biological oxygen demand over time and is a solution to the linear first order differential equation See more The simple Streeter–Phelps model is based on the assumptions that a single BOD input is distributed evenly at the cross section of a stream or river and that it moves as See more • Water pollution • Water quality modelling • Biochemical oxygen demand See more In 1925, a study on the phenomena of oxidation and reaeration in the Ohio River in the US was published by the sanitary engineer, Harold Warner Streeter and the consultant, See more In addition to the oxidation of organic matter and the reaeration process, there are many other processes in a stream which affect the DO. … See more • O'Connor D.

WebThe Streeter-Phelps equations predicted the critical DO sag, or the point downstream at which the levels of DO would reach their minimum. By properly allocating pollution discharge within the watershed and incorporating engineering works to enhance re-aeration, the critical DO sag could be improved.
