According to the news on the website of the Ministry of water resources on May 20, from May 18 to 19, the Ministry of water resources organized the video connection of the first pilot implementation scheme of digital twin basin construction and the typical review (review) of digital twin basin water conservancy project construction scheme in the 14th five year plan in Beijing.
The Ministry of Water Resources said that this video connection opened the prelude to the implementation plan of digital twin basin construction and the review (review) of digital twin basin construction plan in the 14th five year plan. In the near future, the network information office of the Ministry of water resources and river basin management institutions will also organize the review (review) of 52 pilot implementation plans for the construction of digital twin basins, as well as the construction plans of river basin management institutions, provincial water administrative departments and 10 major water conservancy projects during the 14th five year plan.
Digital twin watershed refers to the digital mapping and intelligent simulation of the whole elements of Physical Watershed and the whole process of water conservancy management activities, with Physical Watershed as the unit, spatio-temporal data as the base, mathematical model as the core and water conservancy knowledge as the driving force, so as to realize synchronous simulation operation, virtual real interaction and iterative optimization with physical watershed.
The Ministry of water resources stressed that the construction of digital twin watershed is the core and key to promote the construction of smart water conservancy. The construction of digital twin watershed is an important exploration process, and several principles should be firmly grasped. First, demand traction and application first. The construction of digital twin watershed must serve the application of 2 + n water conservancy business, take demand as the traction, strengthen the "four pre" function, support and strengthen Watershed Governance and management, do not put on airs, but really use it. Second, digital empowerment and ability enhancement. We should coordinate development and security, hold the bottom line and raise the upper limit through digital twin technology, ensure safety and achieve high-quality development. It is necessary to continuously improve the capacity and level of water conservancy management through the construction of digital twin watershed, so as to make the management "more comprehensive, more accurate and more efficient". Third, urgent needs first, demonstration and guidance. We should give priority to urgent needs and play an exemplary role; We should focus on key businesses and highlight advanced technology; We should organically integrate advanced technology with key businesses to achieve the purpose of improving capacity. Fourth, overall planning and step-by-step implementation. We should firmly grasp the two time nodes of the end of this year and the end of next year, strive to be applied in this year's flood season, be meticulous and practical, and achieve results. In the process of implementation, we should build and use at the same time. Fifth, unified standards, interconnection and sharing. We should pay attention to the standardization construction of digital twin basins, make great efforts to solve the problem of "isolated islands" of information, and ensure network interconnection, information sharing and business collaboration. Sixth, the risk is controllable, safe and reliable. We should attach great importance to network security and data security, plan, implement and operate security together with implementation plans and construction plans, so as to control risks and ensure security.
