Focusing on three aspects, Ningxia Autonomous Region has made breakthroughs in digital water control technology research

First, in terms of digital twin irrigation areas and smart irrigation, the bottleneck of the intelligent linkage control algorithm for the entire water canal system in the artesian irrigation area has been broken through, and the full channel system of the irrigation area has been established Intelligent control system; improved intelligent measurement and control integrated gate flow measurement algorithm, improved gate sensing accuracy and controllability; established water network The digital twin modern irrigation district intelligent management cloud platform supports the intelligent management of the million-acre digital water network digital twin modern irrigation district.

Second, in terms of accurate flood forecasting and intelligent dispatch, a multi-source rain monitoring and coupling optimization layout system of satellites, radars, and surface has been constructed, effectively improving the short-term monitoring of heavy rains and floods through integrated sky-ground coupling. The data reliability of emergency forecasting has been improved; a joint precipitation forecasting model with climate models and weather radar has been established to increase the forecast period of flood forecasting from 0.5 hours to 2.5 hours.

Third, in terms of intelligent diagnosis of river and lake water quality and smart river length, a low-cost, multi-parameter, lightweight online monitoring equipment for river and lake water quality has been developed, with the cost reduced by 30% and the performance improved. 30%; established a diagnosis and intelligent evaluation model for key factors of river health; developed an online intelligent analysis model of river and lake water quality that couples monitoring and simulation in real time, and its smart river long cloud platform, which can support all-weather automatic monitoring and real-time dynamic simulation of river and lake water quality and early warning and forecasting of sudden changes in water environment. At the same time, the project created China's first million-acre water network digital water management integrated demonstration area, achieving 6% water saving, 50% labor saving, and 15% energy saving.

The successful implementation of this project will effectively improve the efficiency and management level of water resources in the Ningxia Autonomous Region, realize efficient utilization of water resources in the Yellow River Basin, and assist in the construction of ecological protection and high-quality development pilot areas in the Yellow River Basin. Provided strong support.
