<br/><br/> On the basis of wet season and dry season sampling at points along the length of the Amazon River, at its mouth, and from its 16 large tributaries, the factors that control the salinity and the composition and concentration of the suspended solids of the Amazon River were determined. The multiple regression analysis of the analytical results of 74 river water samples revealed: (1) of the 92% of the variability of the salinity accounted for, 85% was accounted for by relief -77% of the total dissolved salts discharged by the Amazon was supplied from the 18% of the total area of the Basin comprising the mountainous environment-type; (2) of the 62% of the variability of the concentration of the suspended solids accounted for, 43% was accounted for by relief - 72% of the total suspended solids.
