摘要：The present study narrates the geo-environmental setting of the Vamanapuram River Basin (VRB) through the heavy metal assessment in river sediments. The granulometric distribution of trace metals in medium sand, fine sand, very fine sand, silt and clay fractions of the Vamanapuram river sediments has been determined for selected samples and the variation is compared with that of the respective bulk sediments.The order of abundance of trace elements in sand fractions is Fe> Mg> Zn>Mn> Pb> Cr> Ni> Cu> Co>Cd, and in mud fractions is Fe> Mg> Zn> Mn> Cr> Pb> Cu>Ni> Co> Cd. The sediment distribution characteristics have been brought out in a convincing manner.
