Sediment and Nutrient Dynamics in Large Rivers

Session ID#: 24367

Session Description:
The world’s 30 largest rivers contribute ~20% of the 19 billion tonnes of sediment delivered to the oceans annually and are critical conduits for fluxes of Carbon, Nitrogen, Phosphorous and other key nutrients. Much of this sediment is sequestered in large deltas and floodplains, helping to sustain the agriculture that underpins food security for a significant proportion of the world’s population. Therefore, understanding changing sediment and nutrient fluxes in large rivers remains a key focus of Earth scientists. In this session we encourage contributions which seek to explain the shifting nature of sediment and nutrient fluxes to deltas and floodplains under changing driving conditions. We anticipate that the session will be of interest to those with interests including, but not limited to, biogeochemical cycling, flood dynamics and sediment transport and storage. We welcome research which explores these themes through methods such as field observations, numerical models or laboratory experiments.
