Lower Yellow River exemplary three channel shaped dam system

The present invention relates to a wandering lower Yellow River three channel shaped dam system, including training works dam, and the dam latent permeable pile dam; outermost training works of construction of the dam in the design of the main channel, the pilot control Engineering dam embankment dams watertight by the curve radius according to the group consisting groins crest elevation of the design flow rate regulation level plus ultra 1m; feed slide may be submerged in the tail section of the construction of the dam the training works submerged dam crest elevation of the water level is equal to the flow rate regulation; both sides in the groove between two curves River reach straight, laying the permeable pile dam, the dam crest elevation permeable pile when local 800m3 / s water flow rate the same. With this system shaped by three flow paths meet in a small water channel, the water channel, flood control different states of river channel, river regime to achieve stability, enhanced river flood sediment transport capacity, to prevent the Yellow River burst the levee, outburst and other major danger, to achieve the goal of comprehensive management of the Lower Yellow river.
