China's South-to-North Water Diversion middle route delivers over 80 billion cubic meters, benefiting nearly 118 million_我的网站

A |     (ECNS) -- The first phase of the middle route of China's South-to-North Water Diversion Project had transferred more than 80 billion cubic meters of water to northern China as of Friday, directly benefiting nearly 118 million people, according to the Changjiang Water Resources Commission.     The water comes mainly from Danjiangkou Reservoir, where managers balance reservoir inflows, local demand in the Hanjiang River basin, northbound supplies, and downstream ecological needs.        This summer, after forecasts pointed to below-normal rainfall, authorities adjusted reservoir operations to retain about 1.5 billion cubic meters more water as a buffer against possible drought.    Technology is playing a growing role in monitoring water quality.    An AI-powered floating platform works alongside satellites, drones, and ground monitoring stations, feeding data into a digital twin of Danjiangkou Reservoir that tracks water quality, simulates flood scenarios, and supports emergency planning.    At Danjiangkou Reservoir, the core water source for the middle route, an autonomous vessel collects samples from different depths to monitor algae.    Using AI-powered microscopy, the floating station identifies microorganisms quickly and tracks algal activity, giving early warning of blooms.    The vessel is part of an integrated satellite, aerial, surface, and structural monitoring network that combines remote sensing, drones, ground-based stations, and sensors embedded in the dam.    By fusing multi-source data in real time, the system has shifted water monitoring "from isolated points to full-area coverage," said Cui Dongdong, deputy director of the technology development department at a company under the Yangtze River Water Resources Commission of the Ministry of Water Resources.    With the digital platform, a regulation plan that once took days to produce can now be generated in seconds.    The platform runs more than 15 professional models covering flood routing, pollutant dispersion, and dam structure simulation.    The 1,432-kilometer middle route canal carries water across the Yangtze, Huai, Yellow, and Hai river basins before it reaches households in the north.    Water quality has also improved, and the nationally protected "crystal jellyfish," known as the "giant panda of the water," is now sighted frequently in the reservoir, an indicator of excellent conditions.     (By Helen Mo, intern Yang Hongran)                    。    近日，杭州地铁四期工程建设又迎来关键性节点——昨天，记者从杭州地铁获悉，9号线二期工程全线接触网热滑试验顺利完成。这标志着项目已正式具备列车上线运行条件，为后续的联调联试及开通运营奠定了坚实基础。杭州地铁9号线二期工程位于临平区，南起龙安站（不含），北至塘栖站，全长10千米，主要沿荷禹路、康泰路、港北路、绿荫街敷设，全线共设车站7座，无换乘站。可能有市民朋友会好奇，“热滑”究竟意味着什么？简单来说，它是供电系统建成后的关键核验工序，就像给新线路做一次“带电大考”——通过接触网带电行车，全方位校验接触网安装精度、弓网受流匹配性、供电系统运行稳定性，以及轨道、车辆、供电多系统协同适配。这次9号线二期工程全线热滑试验顺利完成，列车全程运行平稳，弓网受流状态优良，各项技术指标全部达标。据地铁相关工作人员介绍，下一步，9号线二期将全面启动多专业联调联试，有序推进通信、信号、综合监控等系统调试，高质量、高标准、高效率完成剩余建设任务，确保线路按期开通运营。
