Abstract
Large quantities of sediment are transported by the River Ganga (The Ganges) particularly In its deltaic region. Attempts have been made to study the physicochemical parameters of the bottom sediments of the River Ganga at various depths at Kamarhati and along the banks of the River Ganga in the lower deltaic region. The results give vital information regarding the pollution load carried by the river and the enrichment of its sediments with nutrients such as P, N and other substances such as C and S (as sulphates). The mobilization of the P, N, C and S (as sulphates) in the sediments is compared with their natural abundance. The enrichment of the river beds with P, the interaction of the sediment and the characteristics of the sediments are ascertained. Some aspects of the phosphorus cycle and its importance are also discussed. The recycling and reuse of sediments for agricultural purposes have been proposed in order to restore ecological imbalances due to nutrient loss.
