Study On The Harm And Countermeasures Of Heze The Yellow River Yellow River Dyke

Heze in Shandong Yellow River is the most upstream river as wide, shallow, chaotic wandering reach, dramatic changes of erosion, scattered broad and shallow water, river regime volatile, mainstream swing frequently, is the famous " tofu back in history " dangerous section. In recent years, after the river training, river regime wandering range has been greatly reduced. But with the river training works artificially produced dike construction, and other human activities near earth embankment and flood high sediment deposition in the main channel flow makes Fluvial fast, slow floodplain sedimentation, siltation and other less affected embankment near the root, so the Yellow River temporary flood levee to the river above the back ground, while the average elevation above the dike beach tender root mean elevation in the Yellow River flood levee formed Pro ditch embankment." especially in recent years, the Yellow River water is small, but also silt difficult year and gradually formed a dike low-lying unfavorable situation, once the flood floodplain, flood low-lying strip of land into the Yellow River dike embankment slope near Kanawha (ie ditch embankment dike river or called) or take the slip string ditch embankment caused by a large river flow phenomenon, formed along the embankment flood, caused by Yokogawa, oblique river embankment serious threat to the security and safety of life and property of the people floodplain, river regulation while increasing difficulty, so that the lower Yellow River flood situation grim, flood control task is arduous.As the main channel siltation atrophy, resulting in increased opportunities floodplain, the water level is high, water withdrawal difficult, but also the production and floodplain security environment deteriorated. Heze floodplain is home to180,000people, the floodplain is the " flood the river," is the survival and development of the masses floodplain homes. In the Yellow River flood occurred when a large floodplain must make sacrifices for the global interest. In order to solve their problems Floodplain people affected after1974after the floodplain are carrying out a security building, the construction of the village station, and retreat road, the people on the beach area to protect lives and property plays an important role. However, due to less investment in the country, the burden of the limited capacity of the masses, can not meet the floodplain security building flood control needs. First Security building less investment, progress was slow. The second is to avoid low water engineering standards, isolated scattered, can not meet the requirements for flood control.Existence is a necessary condition dike along the river flood embankment governance dike embankment along the river is an effective measure to prevent the flood. Carry out countermeasures ditch embankment governance, continue to strengthen the lower Yellow River training works system construction and standardization on the basis of the construction of the dike system, combined with enhanced artificial river silt embankment to prevent flood along the embankment levee seepage improve the ability to slow flood threat along the embankment Kanawha improving the ecological environment.
