This INSPIRE award is partially funded by This effort will improve capability to predict earth and ecosystem dynamics. Such Earthcasting capability is needed to achieve long-term sustainability of land, water, and ecosystems. The central contribution of the proposed research will be to determine how basic processes interact to control important outcomes in river and floodplain environments. This effort focuses specifically on river systems because they support extensive human populations and are tremendously important to storage, processing, and export of carbon, sediments, and nutrients. This project will develop the essential underpinnings of Earthcasting and work with leading data collection efforts in the U.S. and Europe to translate these fundamental advances into practical management strategies. The project team will also use these scientific gains as the basis for educational programs delivered both through virtual courses and live outreach activities.
