联合国海洋十年“大河三角洲计划”（Mega-Delta programe）旨在推动三角洲区域可持续发展。河口海岸数字孪生系统，通过集成观测数据和跨学科模型系统，应用最新的大数据管理和人工智能数据挖掘技术，正成为大河三角洲计划成功落地的先进手段。为更好地服务于全球特大三角洲的科学研究、工程应用和应急管理，作为大河三角洲计划的发起单位，华东师范大学河口海岸学国家重点实验室，将建设河口海岸数字孪生系统作为未来五年的核心任务。基于观测数据和多学科模型系统的扎实基础，河口海岸数字孪生系统将以长江河口数字孪生系统建设作为首要任务。为增进对数字孪生框架、核心技术及应用场景的了解，河口海岸学国家重点实验室将举办第一届河口海岸数字孪生系统国际研讨会。该研讨会旨在增进了解，交流思想，促进河口海岸数字孪生系统的发展。该研讨会同时收到联合国海洋十年“海洋数字孪生”计划的特别邀请，成为海洋数字孪生国际峰会的分会场。
Mega-Delta Programme, endorced as part of the UN Decade of Ocean Science for Sustainable Development, has the overall objective to support sustainable development in delta regions. Integrated framework of observations and numerical modelling system, supported with the newest technology of big data management and artificial intelligence for data analysis, is becoming the right way to guarantee the success of the Mega-Delta Programme. Therefore, as the leading institute of Mega-Delta Programme, the State Key Laboratory of Estuarine and Coastal Research in East China Normal University decided to promote the development of the Digital Twin of Estuarine and Coastal System, in order to better serve the scientific research, engineering applications and emergency management on the mega deltas over the whole world. The first step is to develop the digital twin system of Yangtze River Estuary, based on the solid foundation of observations and multi-disciplinary modelling systems. So far, the development of digital twin system of Yangtze River Estuary confronted great challenges ranging from the understanding of conceptual models, integrating core technologies and creating application scenarios. This event is the first symposium on digital twin of estuarine and coastal system, and the aim is to enhance the understanding and exchange ideas of the digital twin of estuarine and coastal system. This symposium has received the special invitation from the digital twin of the ocean program which is endorced as part of the UN ocean decade. Currently it is listed as one of virtual satellite events in the international digital twin of the ocean summit.
