The identification and estimation of discrete-time models of BOD-DO (Biochemical Oxygen Demand-Dissolved Oxygen) in river systems is considered using a multivariable extension of the instrumental variable approximate maximum likelihood techniques of time series analysis. The dynamic water quality models relate water quality at specific points on the river and are used in a design study to evaluate the performance of artificial aerators in the River Cam. Operating schemes are developed which utilise closed loop state variable feedback control and feedforward control to maintain adequate levels of dissolved oxygen in the river.
