The Harnessing History and Countermeasures Research of the Yellow River Estuary Channel

The harnessing of Yellow River estuary is a very important part of the Yellow River harnessing, which is related to the flood control safety of the downstream of the Yellow River and the economic and social development and the benign maintaining of Yellow River delta ecology. This article has analyzed the Yellow River delta evolution since 1855 and the variation situation of flow course for different periods, while concludes the main harnessing process and harnessing measures of Yellow River estuary. Viewing from requirements of keeping the healthy life of the Yellow River and ensuring the sustainable development of estuary region, it presents such countermeasures as to further enhance the engineering flood control construction, to stabilize the flow course of Qingshui Gully, to schedule the spare flow course, to well deal with the relationship between Yellow River estuary harnessing and the economic and social development and benign ecological maintaining, and to establish a perfect scientific management system.
