This INSPIRE award is partially funded by the Hydrologic Sciences Program in the Division of Earth Sciences in the Directorate for Geosciences, the Geomorphology and Land Use Dyanmics Program in the Division of Earth Sciences in the Directorate for Geosciences, the Ecosystems cluster in the Division of Environmental Biology in the Directorate for Biological Sciences. Most natural systems are structured by diverse processes that operate over a wide range of scales, but current understanding is derived primarily from controlled investigations of isolated subsystems with suppressed complexity. As a result, available models for landscape and ecosystem dynamics consider only a very limited range of processes and scales, and this incomplete understanding sharply limits our ability to predict future system trajectories. The project team will develop a general trans-disciplinary basis for Earthcasting coupled system dynamics by providing the theory, models, and data needed to relate local dynamics of water, soils, sediments, cells, carbon, and nutrients to large-scale geomorphological, ecological, and biogeochemical outcomes. The project team will explore the underlying structure and connectivity of river networks to provide a common basis for linking physical, ecological, and biogeochemical dynamics in watersheds. This work will exploit concurrent advances in theory for stochastic transport and dynamical processes on networks to develop methods for probabilistic prediction across scales. The resulting holistic, multi-scale simulations will be used to design data collection strategies that better consider the underlying system dynamics. By advancing general theory for anomalous transport on complex networks and partnering with diverse data collection efforts, this project will develop both the theoretical and observational basis for Earthcasting. The research effort will be linked with integrative, trans-disciplinary education in earth, ecosystem, and sustainability science. The project team will develop a cross-cutting course on fluvial system dynamics and related stand-alone educational modules on geomorphological and biogeochemical processes, and deliver them via an innovative web-based, multi-institutional format. Subsequently this material will be developed into a massive open on-line course (MOOC) focused on Earthcasting. The project includes eight international research partners from seven countries including Spain, Canada, the United Kingdom and Austria. 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.

该INSPIRE奖部分由地球科学理事会地球科学处的水文科学计划，地球科学理事会地球科学处的地貌学和土地利用动态计划，生物科学理事会环境生物学处的生态系统集群资助。 大多数自然系统是由不同的过程，在很大范围内运作的规模，但目前的理解主要是来自孤立的子系统与抑制复杂性的控制调查。因此，现有的景观和生态系统动力学模型只考虑非常有限的过程和尺度范围，这种不完整的理解严重限制了我们预测未来系统轨迹的能力。该项目团队将通过提供将水、土壤、沉积物、细胞、碳和营养物的局部动态与大规模地貌、生态和地球化学结果联系起来所需的理论、模型和数据，为Earthcasting耦合系统动力学建立一个通用的跨学科基础。项目小组将探索河流网络的基本结构和连通性，为连接流域的物理、生态和地球化学动态提供共同基础。这项工作将利用随机运输和网络上的动态过程的理论的同步进展，开发跨尺度的概率预测方法。由此产生的整体，多尺度模拟将用于设计数据收集策略，更好地考虑潜在的系统动态。通过推进复杂网络上异常传输的一般理论，并与各种数据收集工作合作，该项目将为Earthcasting开发理论和观测基础。研究工作将与地球，生态系统和可持续发展科学的综合，跨学科教育相联系。该项目小组将开发一个关于河流系统动力学的跨领域课程以及关于地貌和生物地球化学过程的相关独立教育模块，并通过创新的网络多机构形式提供这些课程。随后，这些材料将发展成为一个大规模的开放式在线课程（MOOC），重点是Earthcasting。 该项目包括来自西班牙、加拿大、联合王国和奥地利等七个国家的八个国际研究伙伴。这项工作将提高预测地球和生态系统动态的能力。要实现土地、水和生态系统的长期可持续性，就需要这种地球投射能力。拟议研究的核心贡献将是确定基本过程如何相互作用，以控制河流和洪泛区环境中的重要结果。这项工作特别关注河流系统，因为它们支持广泛的人口，并且对碳，沉积物和营养物质的储存，加工和出口非常重要。该项目将开发Earthcasting的基本基础，并与美国和欧洲的领先数据收集工作合作，将这些基本进展转化为实际的管理策略。项目团队还将利用这些科学成果作为通过虚拟课程和现场推广活动提供的教育计划的基础。
