Chemical of sediment characteristics of the upper reaches of Cauvery estuary, east coast of India

Major and minor element geochemistry of water and suspended and bed sediments collected from upper reaches of the estuary are studied to understand the geochemical processes in tropical estuarine systems. Suspended sediment concentrations increase downstream with chlorinity. All the major dissolved...

Description
Summary:Major and minor element geochemistry of water and suspended and bed sediments collected from upper reaches of the estuary are studied to understand the geochemical processes in tropical estuarine systems. Suspended sediment concentrations increase downstream with chlorinity. All the major dissolved elements like Na, K, Ca, Mg and Si show conservative behaviour. Dissolved phosphate is non-conservative. The phi mean size of sediments increases downstream. Clay minerals in the suspended sediments are predominently kaolinite, illite and montmorillonite. Si is most dominant element in the sediments followed by Na, Al, Ca, Fe, K and Mg. Heavy metals are enriched in the suspended sediments compared to the bed sediments.
