Analysis of Effects and Countermeasures of Embankment for Agricultural Production on River Training in the Lower Yellow River

摘要

The Yellow River is a sediment-laden river. Its river course in the lower reaches is very hard to train.Achievements have been gained in river training and safety of flood control has been guaranteed. With inflow becoming low in the lower reaches, ratio of flood peak occurrence decreasing, embankment for agricultural production aggravates sediment silting in the river channel, which produced negative effects on river engineering. The river training strategy "stabilizing the main channel, water and sediment regulation, widening the river and strengthening levee, compensation by policy" should be further carried out. Flood diversion to warp floodplain, strengthening the safety construction of the floodplain, abolishing the embankment for agricultural production should be the emphasis and direction of river training in the lower reaches.
