Approach to Secondary Elevated River Harnessing of the Lower Yellow River

It analyzes the situation and origin of the secondary elevated river on the lower Yellow River and puts forward the principles of overall planning,unified planning with due consideration for all concerned,combining short-term and long-term plans together,treating a disease by looking into both its root cause and symptoms and conducting integrated management according to the necessity and urgency of the secondary elevated river harnessing.The main measures include a) to speed up the consolidation and protection works of serious secondary elevated river section;b) to clear away the obstacles for flooding including production dykes and fill floodplain and scour channel by major floods;c) to divert floods for filling floodplains by normal floods;d) to dredge channel,silt-up borrow bits and block branches manually and;e) to fill-up low-lying areas near the embankment combining with the works of the Yellow River diversion and desanding.It should conduct planning and pilot work and strengthen relevant studies in the near future.
