| Session Description |
Large rivers act as conduits for transferring sediment and nutrients from terrestrial sources to the coastal shelf. This role has motivated geoscientists to explore a number of issues concerning quantification of the sediment flux and denudation rates, articulation of source to sink sediment cascades and estimation of sediment and carbon budgets. Human-induced changes in river basins, particularly those associated with the retention of sediment behind impoundments, have implications for large scale geochemical cycles and, in turn, for the functioning of aquatic ecosystems. The aim of this session is to explore knowledge of the sediment, carbon and geochemical fluxes in river basins, with particular attention to Asian rivers where the magnitude of human impact through land use change and water resource management has increased rapidly. Geomorphological processes influence soil and sediment mobility therefore having a strong influence on the storage and sequestration of carbon, yet the dynamics of carbon transport within river basins remains poorly understood. |
