Core Viewpoint - The article highlights the severe drought conditions in the Huai River basin and the proactive measures taken by the Anhui provincial water conservancy department to ensure water supply for urban residents and agricultural irrigation through major water diversion projects. Group 1: Water Diversion Projects - The Yangtze River water diversion project has played a crucial role in combating drought, with the East Fei River section being a key node where water is pumped and diverted into the Huai River. Since the opening of the East Fei Gate on July 18, approximately 1.89 billion cubic meters of water have been diverted over 12 days [2]. - The Huai Water North Diversion Project, an extension of the Yangtze River diversion project, has also been significant in providing water. As of July 31, 2023, it has supplied 17.61 million cubic meters of water to Suzhou and Huai Bei, with a total of 59.99 million cubic meters supplied this year [3]. Group 2: Regional Drought Impact - The city of Huainan has experienced a drastic reduction in rainfall, with only 17 mm recorded in July, a decrease of 80%-90% compared to the same period in previous years. The city has relied on the first phase of the Yangtze River diversion project for approximately 1.89 billion cubic meters of water to support agriculture [4]. - In Fuyang, the average rainfall has been only 14 mm since late June, down over 90% from the norm. The city has intensified its drought response, extracting over 200 million cubic meters of water since late June, a threefold increase compared to previous years [4]. - The Cihua New River irrigation area has also been active, with the management bureau operating the pumping station for 58 days, extracting 3.81 billion cubic meters of water to meet urban and agricultural irrigation needs [4].
