Approach for estimating salt export from the River Murray System to the Southern Ocean
The Basin Plan sets out a salt export objective (section 9.09) to ensure adequate flushing of salt from the River Murray System into the Southern Ocean. The Authority must estimate the discharge of salt from the River Murray System into the Southern Ocean every water accounting period.
This report describes an interim approach to estimate salt export (tonnes of salt) over the barrages using average salt concentration (salinity) from several locations within Lake Alexandrina and the estimated water flow over the barrages. The interim approach is required to assess the relative differences of three different methods for estimating water flow over the barrages.
