Large rivers serve as conduits that transport and store the products of erosion from mountain belts to deltas and the oceans. Riverine dissolved inputs also moderate the geochemistry and isotopic composition of the oceans. There are now a variety of records for large rivers that document fluxes of water, sediment, and elements (for example, carbon, nitrogen, strontium, neodynium) in modern rivers, as well as records of riverine outputs stored in floodplains, deltas and deep-ocean fans. These records are often used to identify provenance, estimate denudation rates, and to infer the degree to which erosion is influenced by tectonics and/or climate. The better integration of sedimentological and geochemical datasets has the potential to provide fundamental new insights into how mass flux links to topography, climate, vegetation and human impact from uplands to lowlands and beyond to the ocean.
We specifically welcome papers on modern, Holocene and Late Cenozoic riverine systems and geochemical and mass flux records that are, or could be, interrogated to document relationships between Earth surface processes, climate, vegetation, carbon and topography. An additional aim of this session is to gauge interest in developing a large integrated study encompassing all the major Himalayan rivers in order to produce higher temporal resolution datasets exploring seasonal and interannual variability in mass and geochemical fluxes.
