In paper 1 (Dietrich et al., this issue) a model was derived for the transport of a conservative solute along a stream connected to an aquifer. In this paper the model is applied to a 207‐km reach of the River Murray in Australia. The appropriate model structure and its parameter values are determined using principles of system identification. The major tools applied are instrumental variable estimation techniques. Accurate downstream salinity prediction is obtained on independent data sets not used for model calibration.
