Estimates of catchment salt balances throughout the Murray-Darling Basin (MDB) suggest mobilization of salt stores and generally increasing stream salinities. It is widely assumed these salts are rainfall-deposited cyclic salts of marine-aerosol origin, concentrated by evapotranspiration, stored in groundwaters and mobilized by clearing of native vegetation. In this paper, the assumptions about the sources of salts, in upland catchments in the south-eastern region of the MDB are re-evaluated....[Show more]
