长江镇扬河段河势的自然演变、恶化，已威胁防洪安全且制约沿江国民经济发展。河段内以和畅洲汊道变化最为剧烈，洲头崩退、汊道内部崩岸时有发生，导致主支汊易位，河势不稳严重影响“黄金水道”安全畅通。在采取了平顺抛石护岸、窝塘沉梢促淤、砂枕潜坝束流等综合治理工程措施后，得到一定程度改善，和畅洲汊道河势趋于稳定，取得了比较理想的整治效果。整治措施对长江分汊河道治理具有一定启示。

The natural evolution in Zhengyang section of Yangtze River threatened seriously to the safety of flood control and restricted the economic development along the river. The river change at Hechang Island was the severest in the Zhengyang section. The island-head landslide back and bank collapse happened frequently. It caused the river regime change from main channel to branch. The instability has seriously affected the normal operation of the national facilities and the safety and smooth of the golden waterway. After taking a series measures such as riprapping revetment, sinking trees into socket pools to promote deposition, filling sand bags to structure submerged dam to restrain flow, the river pattern of Hechang Island graduates into stability and gets some improvements. The effects of these control measures are outstanding, the regulation practice will give an enlightenment for the people who are working on the Yangtze River braided river regulation.
