Abstract

A comprehensive set of field data is presented for purposes of identifying and verifying dynamic models of DO-BOD-algae interaction in a freshwater river. Several models derived on the basis of these field data are reported and their fitting error statistics are compared. A number of grounds for criticism of the models are discussed and, in particular, it is suggested that further analysis should be undertaken along the lines of more conventional advection-diffusion representations of a river's transport and dispersive properties. A summary of directly supporting studies on system identification, parameter estimation, model interpretation, and model application in operational control contexts is given, principally in the form of an appendix of abbreviated notes.
