River regulation measures

(1) Protection and Utilization of Tidal Flat Land

The beach is a unique product of mountain streams and rivers. Generally, the floodplain of the river is relatively open, and the floodplain is flooded in flood season, which is beneficial to flood discharge and detention. Its functions should be preserved and fully developed. The river course flowing through the urban area, while maintaining the flood discharge function of the beach, uses the beach to set up green spaces, parks, traffic auxiliary roads and sports venues to give play to its leisure and hydrophilic function and become a good place for citizens to entertain, exercise and play.

In the regulation, it is necessary to conform to the river regime, maintain the floodplain and bend, restore the natural form of the river, reduce the slope of the river bed, reduce the flood level and pressure, and at the same time reduce the height of the flood dike. In addition, the curved water flow is more conducive to biodiversity and creates a suitable living environment for all kinds of cattle.

(2) Design of composite section

Rivers with mountain streams are generally wide, and the cross-section design of rivers can adopt the form of compound cross-section. In dry season, the flow is small, and the water flows to the main channel of the channel; In flood season, the flow is large, allowing flood to flood the beach, the cross section is large, and the flood level is low, so it is generally unnecessary to build a tall levee.

In the dry season, according to the width, topography and landform of the floodplain, combined with local conditions, give full play to the functions of the floodplain: if the floodplain is wide, large or comprehensive sports fields such as golf courses and football fields can generally be developed; Small outdoor activities, riverside parks or auxiliary roads can be built on the relatively narrow floodplain. Rational development and utilization of the floodplain can not only give full play to the function of the floodplain, but also not raise the flood level and increase the flood control pressure on both sides of the strait.

(3) The design of short and fat dam that can prevent scour and flood.

Shanxi River has the characteristics of steep riverbed slope and sudden flood, with short high water level, concentrated flow and high velocity, which seriously scours dams and farmland along the river. Through planning, a low-fat dam type with anti-scour and non-flood protection is adopted, and the downstream dam section of the reserve is opened. Rivers also provide a way out for floods, allowing low-frequency floods to overflow the dam, ensuring that the dam will not collapse and farmland will not be destroyed.

In rural rivers with flood control as the main function, the dike foundation is seriously eroded, so loose pile foundation can be used. Loose pile foundation has the advantages of less investment, good integrity and strong erosion resistance, so as to improve the integrity and stability of the dike.

(4) Biological dike reinforcement is adopted to reduce dike hardening.

For the rural river courses in the site, except for some severely scoured river banks, dikes should be built for slope protection, and the original natural features, such as the floodplain, Jiang Xinzhou, coastline and floodplain on both sides of the river, should be kept as much as possible, and the original wetland ecological environment should be kept, so as to reduce the damage of the project to the natural features and ecological environment.

In dike construction, pebbles and dry stones can be used to protect the bank, so that the river bank tends to a natural shape. The inner side of individual dikes can be protected by planting straight-rooted tree species such as Metasequoia glyptostroboides or lawn slope protection.
