Predicting the fate of river deltas and coastal wetlands: remote sensing, numerical modeling and field advances
Session ID#: 157589
Session Description:
River deltas and coastal wetlands are among the most valuable ecosystems on Earth, for example providing coastal protection against storm impacts and sequestering carbon. However, these coastal ecosystems are threatened by global climate change, land loss, and anthropogenic activities, with long-term sustainability dependent on sediment delivery and biological productivity.
Predicting the fate of these environments is particularly challenging because they are governed by multiscale interactions between vegetation, sediment transport and water flow. Therefore, predicting the impact of anthropogenic activities on deltas and wetlands requires cross-disciplinary research including advances within the fields of hydrology, geomorphology, and ecology. In this session, we encourage the presentation of innovative research that integrates multiple novel methods such as remote sensing, numerical modeling, flume experiments, and in-situ field measurements to help understand vital coastal processes and improve predictions of coastal resilience at landscape, regional, and global scales.
