WebFeb 10, 2024 · Abstract. Suspended sediment plays a vital role in the regional and global cycling of carbon and nutrients by carrying carbon and nutrients from headwaters into lowland rivers and the oceans. Sediment transport through river systems is often fundamentally modified by human activities such as reservoir management. However, a … WebMuch of the bed load, however, cannot be sampled by existing techniques, as it moves too near the bed of a stream. It is fortunate, therefore, that the greatest part of the total sediment load is in the form of suspended load. When a dam is constructed, the sediment transported by a stream is deposited in the still waters of the reservoir. WebIn the environment, a pollutant is rarely present alone, and other contaminants can influence its fate. To investigate the influence of the presence of other pollutants on the sorption of pesticides and trace metals (TM), the adsorption of Aclonifen, alachlor, Cd and Cu onto suspended particulate matter (SPM) was studied.
