Abstract: Two radically diff erent approaches to the ma thematical modelling of salt transport in a long river system are described. They have been applied to different sections of the River Murray which have diff erent characteristics. The calibration of these models permitted quantitative estimates to be made of the water loss occurring in transmission due to evaporation and of the salt inflow. to the river from saline groundwater sources. The two models have been operated together to reproduce salt movement down 1900 kom. of Australia's longest river. The models have been used to evaluate salinity changes that would arise if proposed salt' interception schemes or changed river management policies were introduced. The results of these studies provided essential inf ormation required for the formulation of a water quality management strategy for the River Murray.
