Abstract:With the development of economy and continuous advancement of infrastructure construction,there have been more intensive sand and quarrying activities in some rivers.At present,with the increasing awareness of ecology and environmental protection,disorderly mining activities have basically disappeared,but the impact will not be eliminated in short term.The impact of sand quarrying of Hongdengqi Beach in the upper reaches of the Yangtze River is reflected in weakened function of the channel regulation building and deteriorating waterway conditions,which threaten the safety of navigation.In the channel maintenance,the original function of the channel regulation building will be restored by taking engineering measures to prevent the shallow channel of the river section hinder navigation,which has achieved good results and laid a foundation for further improvement of the channel.
