摘要：

Based on preliminary investigations, over the period of two years, the chemical quality of the Ganges, Indus, Brahmaputra, Narmada, Tapti, Mahanadi, Godavari, Krishna, Tungabadra and Cauvery rivers have been evaluated. The discharge-weighted composition for Indian rivers has been calculated and compared to the world average river water. The Indian rivers are alkaline and about 25% more concentrated in dissolved salts than the world average. Discharge and downstream variations in the water chemistry for a few selected stations are briefly explained. The range of values for suspended sediments transported by the rivers are shown together with limited seasonal, discharge and downstream variations. Chemical, sediment and total load have been calculated for Indian rivers and erosion rates are compared to data for some major world rivers. The chemical data of river waters have been used to predict theoretically the mineral assemblages in carbonate and silicate systems. Preliminary studies, using X-ray diffraction, have been made on the suspended sediments and the results are compared to theoretical predictions based on water chemistry. © 1979.
