摘要

The detrimental impact of sediment and associated pollutants on water quality is widely acknowledged for many water sources (Rickson 2014). There is increasing recognition that fine sediment represents an important diffuse source pollutant in waters surface (Walling and Collins 2008). In many cases, toxic substances can be absorbed by sediment particles and then transported to other areas. Studying the quantity, quality, and characteristics of sediments in the stream helps scientists and engineers to determine the sources and evaluate the impact of the pollutants on the aquatic environment. Recognizing the role of suspended sediment (SS) in the transportation of major elements from land to rivers is necessary (Chau 2006). In this study we tried to evaluate the role of SS in transportation of calcium, magnesium, nitrogen and phosphorus to the river. We also estimated the percentages of each of the above mentioned elements which carried on SS to the total amounts transported as dissolved and particulate forms. The results therefore help managers and decision makers to properly designate control strategies in the study area.
