EC34C:
Geological and Biogeochemical Dynamics in Major Deltaic Coasts II Posters


Session ID#: 9355

Session Description:
River deltas occupy only 5% of the Earth’s surface, but nourish over a half billion people around the world. Deltas play a vital role in transferring water, sediment and nutrients to the global coastal ocean. Many river deltas, however, are endangered because of rising relative sea level and coastal erosion, leading to significant threats to natural, economic and social systems. During the past half century, lots of deltas have been impacted by human activities, such as levee construction, dam construction-induced sediment decline, as well as fertilizer-induced coastal hypoxia. In this session we encourage the submissions of the studies on geological processes, biogeochemical processes and the interaction of two in dynamic major deltaic systems through the use of field observations, numerical models, or laboratory experiments. We propose to gather presentations that highlight recent findings on various aspects of deltaic sciences, including coastal morphodynamics, sedimentary geology, sediment transport, coastal restoration, biogeochemical cycles, as well as the linkages of water-column and seabed processes. Studies on the Mississippi and Yangtze dispersal systems are particularly encouraged, and the studies in other deltaic systems are certainly welcome.
