Abstract

The dissolved inorganic carbontransported by rivers as bicarbonate ions originates mainly from two sources: i) the dissolution of carbonate minerals which outcrops in the substratum of the drainage basin and ii) the dissolved CO2 in the soil leaching water which participates as H2C03 to the weathering of most of the minerals. In order to distinguish these two sources in the bicarbonate flux transported by the Garonne river, wwe have applied a model of decomposition of dissolved major elements (MEGA model) to monthly fluxes of elements transported in solution by the Garonne river from 1971 to 1991.
