分洪工程将超过河道安全泄量的洪水分走或进行滞蓄,以减轻洪水对原河道下游的威胁,避免造成严重灾害所采取的工程措施。分洪是防洪体系中的重要组成部分。长江荆江分洪工程在荆江出现较大洪水时,把超过安全泄量的部分洪水分蓄在特定的范围,以保证荆江两岸及荆江大提安全的工程。它是长江中游污洪体系中的一
Flood diversion project will be more than the discharge of flood discharge or stagnation to reduce floods to the downstream of the original river threat to avoid serious disaster caused by the engineering measures taken. Flood diversion is an important part of flood control system. When the Jingjiang flood diversion project in the Yangtze River has a relatively large flood in Jingjiang River, some of the flood water that exceeds the safe discharge amount is stored in a specific area to ensure the safety of the two sides of the Jingjiang River and the Jingjiang River. It is one of the flood control systems in the middle reaches of the Yangtze River
