The reason why Zhuozhou, Hebei Province was flooded was that heavy rainfall prevented the water from being drained out.
From 8:00 on July 29 to 11:00 on August 1, 2023, an obvious precipitation weather process occurred in Zhuozhou City, Baoding, Hebei Province. The city's average precipitation is 355.1 mm, with the maximum precipitation being 435.7 mm in Lianghe Village. The precipitation in many towns and streets exceeds 300 mm. At the same time, affected by the transit of upstream floods, the risk of river flooding and urban waterlogging in Zhuozhou City has intensified, and the flood control situation is very serious. Super large water flow is the fundamental cause of floods in Zhuozhou, and topographic characteristics aggravate the flood situation.
From the mountainous areas in the upper reaches of the Beijuma River and Dashi River to the plains of Zhuozhou, there is no transition zone in between. Such terrain will lead to greater flow and greater flow velocity. After the water flows from the mountainous area into the plain, the river channel becomes gentle. If the flow rate is low at the same flow rate, the water level will rise. This is one reason why the water in Zhuozhou is particularly deep.
Measures for flooding in Zhuozhou, Hebei:
This flood involves four river basins in Hebei - Daqing River, Yongding River, Ziya River and Beiyun River. At present, Hebei Province has activated seven flood storage and detention areas in three river systems: Yongding River, Daqing River and Ziya River. Among them, the Xiaoqing River and Langouwa flood diversion areas are located around Zhuozhou and are also the two flood diversion areas of the Daqing River North Branch.
They funnel the water from Baigou River and Nanjuma River into Dongdian through the newly constructed flood diversion channel in Xiongan, then pass through the Dongdian flood storage and detention area, pass through Tianjin Duliujian River, and finally collect To the Bohai Sea. As the rescue continues, the rescue channel has been opened and the trapped people are being transferred one after another. Zhuozhou City has established 28 emergency rescue teams with a total of 8,755 people, and they work closely with professional rescue teams such as the troops stationed in Zhuozhou and the Blue Sky Rescue Team. In addition, rescue teams from Shandong, Jiangsu, Anhui and other places rushed to the scene to provide reinforcements.
