This paper analyzes estuary channel regulation projects at home and abroadand draws experience as follows.The regulation of big river estuary waterway is difficult and needs a long cycle.The regulation of mouth-bar channels is the key.Different estuarine hydrographic and sediment characteristics changes widely,so the regulation scheme needs to be appropriate.In the estuary channel regulation,the combination of regulation and dredging is widely used,and most of them are based on the renovation.Attentions shall be paid to the channel construction and comprehensive management of the estuary.The implications of Yangtze estuary waterway regulation are as follows.Regulation and dredging are combined in the Yangtze River estuary channel.It uses many means and program research to develop a reasonable plan.In the construction period of the project，field observation and dynamic management shall be strengthened.Practice shows that the regulation of the Yangtze estuary channel is quite difficult,so we must deepen the understanding on the estuary of water sediment movement,and keep innovation,so that we can achieve the desired objective.
