The construction of the Xiaoqinghe digital twin watershed has achieved initial results: the flood control has basically achieved intelligence

On September 8, the Shandong Provincial Department of Water Resources held a press conference to introduce the situation of technological innovation boosting the high-quality development of water conservancy. The reporter learned from the meeting that the construction of the Xiaoqing River digital twin watershed has achieved initial results, and the "four preliminaries" intelligent system for flood control in the basin has been initially constructed, which has provided strong support for strengthening the governance and management of the Xiaoqing River basin. In recent years, the Shandong Provincial Department of Water Resources has actively organized and carried out major water conservancy scientific research, vigorously promoted the integration and application of high and new technologies such as satellite remote sensing, big data, BIM, and digital twins in the water conservancy industry. , production and construction project supervision and management, key project supervision and inspection, etc., provide strong scientific and technological support for promoting the high-quality development of water conservancy.

The national "14th Five-Year" new infrastructure construction plan clearly states that it is necessary to promote the construction of digital twins, intelligent simulation and intelligent business applications of large rivers and lakes. What is the progress of Shandong digital twin watershed construction? At the press conference, Zhu Yufen, deputy director of the Science and Technology and Foreign Cooperation Division of the Shandong Provincial Department of Water Resources, introduced that at present, our province is accelerating the progress of the Mihe, Xiaoqinghe, Dagu River, and Huanglei River in conjunction with the water conservancy projects under construction. The pilot construction of digital twin watersheds (projects) such as and Jiaodong water transfer project, among which, the construction of the Xiaoqing River digital twin watershed has achieved preliminary results, providing strong support for strengthening the governance and management of the Xiaoqing River basin.

It is reported that after the flood season in 2019, our province invested 18.2 billion yuan to implement the Xiaoqing River comprehensive flood control project. The flood control engineering system was upgraded. Among them, 257 million yuan was invested in the construction of the automatic dispatching and command system, and the main construction contents included four major parts: information monitoring, application integration, network communication , physical environment and security.

Li Zhanhua, director of the Planning Department of the Xiaoqing River Basin Water Conservancy Management Service Center in Haihe, Huaihe, Shandong Province, introduced that at present, Xiaoqing River has basically built a basin digital scene, and constructed a "one map". The monitoring and perception system covers the whole basin, involving 11 drainage pump stations and 27 control sluice stations for trunk lines and flood diversion channels and integrate BIM models of 62 key water conservancy projects. Preliminary realization of intelligent simulation, integration and integration of various real-time water monitoring information, realization of flood evolution simulation for 8 reservoirs in the basin, construction of forecasting plans for 57 sections, 49 displacement monitoring sections and 23 seepage pressure monitoring sections. Real-time intelligent safety monitoring and dike safety warning. At the same time, actively explore the direction of smart watershed construction and provide experience for the construction of digital twin watersheds in our province. During the flood season this year, the project is in trial operation, and the flood control in the basin is basically automated, intelligent and visualized.

Currently, the Ministry of Water Resources is carrying out pilot projects for the construction of digital twin watersheds in many places across the country. Among them, the pilot implementation plan of Xiaoqinghe digital twin construction has been reviewed by experts from the Ministry of Water Resources, and domestic and foreign experts will be organized for technical consultation in the near future. Li Zhanhua said that in the next step, our province will deeply search for shortcomings, actively promote the construction of the Xiaoqing River digital twin basin, and provide strong support for strengthening the unified governance and management of the Xiaoqing River basin, and strive to form a national leading, replicable promotion experience practice.
