Deposited Sediment Source Fingerprinting in a Tropical Environment

摘要

Water erosion promotes water quality impairment and siltation of streams and reservoirs. Finding the origin of the sediments can ensure high agricultural productivity with preservation of natural resources, by targeting sediment control strategies. Use of soil tracers in soil erosion has been proposed. Methodologies are based on the principle that suspended sediments retain some of the properties acquired at their origin such that a sediment sample transported through the landscape can be compared tothose from potential sources within its watershed.
