Abstract

Integrated chemical and stable isotope analyses were used to define the controls on the dissolved inorganic load. The dominant sources of ions in the river are atmospheric deposition and rock weathering. The input by weathering is largely controlled by dissolution of carbonate and evaporite minerals. Calgary is the most significant point source input along the ri Stable isotope data indicate that discharge in the fall and winter is fed by groundwater. The high discharge event in the spring is a mixture of snowmelt and displaced groundwater. Summer discharge is fed by rainfall. Despite seasonal variations in th The chemical denudation rate for the Bow River at Banff is 678 kg/ha/y. The denudation rate for the basin as a whole is 340 kg/ha/y. Loading from Calgary accounts for 8 to 9% of the mass flux out of the basin in the spring and fall and 25% of the mass
