How many meters is the protection scope of the river embankment?

This is not fixed for many meters, but too close will affect the flood control ability of the river, which depends on the regulations of your local county government. General river management scope is as follows:

1, rivers with dikes are within the range of 8 meters to 15 meters on both sides of the toe line outside the dike;

2, no embankment of the river, for the upper reaches of the river on both sides of the extension of eight meters to twenty-five meters;

3, flood control and moisture-proof seawall, for each side of the embankment toe line extension within 30 meters to 50 meters;

Including river waters, sandbars, beaches, dikes, coastlines, etc. Planning the reserved scope of river regulation and protection outside the scope of river management for river widening, regulation, ecological landscape and greening; The main function is to control the waters from being illegally filled and blocked, and to ensure the safety of flood control. According to the water conservancy and other river planning approved by the municipal and district water conservancy administrative departments, the relevant laws, regulations and technical standards shall be followed, and the control line of land use scope for river planning shall be delineated. Generally, it consists of five lines, including estuary line, river center line and land control line.

River regulation measures:

1, dredging project, the river course in the village is generally narrow, and the flood discharge capacity is obviously insufficient. Dredging and dredging can greatly increase the flood discharge capacity of rivers, clean up silt and garbage, and improve the water environment of rivers. However, we should not blindly pursue the smoothness of the river and destroy its original curvature. We should keep the beaches and sandbars in the river.

2, slope bank regulation project, in the slope bank regulation, according to different river sections to choose a reasonable section design, mainly in the following forms. Form 1: Slope-type masonry ecological revetment, which is mainly used in river sections with fast flow speed, large slope and open construction space. Form 2: Slope cobblestone ecological revetment, which is mainly used in the reach with slow river flow. Form 3: Vertical stone revetment, which is mainly used for river sections with relatively high requirements for flood control and scour prevention and limited by topography. Form 4: Natural vegetation revetment, mainly distributed in production areas such as farmland or river sections with low requirements for revetment.

3. Water system connectivity project: improve the drainage system of the river by carrying out the water system connectivity project, make the water flow smooth, build a weir to lift water, form a water surface and wet environment, and improve the flood control and drainage function of the water system.

4, hydrophilic, landscape greening project, in order to stabilize the river bank, prevent soil erosion, beautify the river bank landscape, in accordance with the requirements of appropriate total amount, reasonable collocation, plant diversity in rural areas on both sides of the river. If conditions permit, waterfront facilities such as leisure platforms and hydrophilic plank roads can be appropriately added to create a space for entertainment, leisure and activities for residents.

Regulations of People's Republic of China (PRC) Municipality on River Management

Article 19 Where a province, autonomous region or municipality directly under the Central Government takes a river as its boundary, it is forbidden to build drainage, water blocking, water diversion, water storage and river regulation projects without the consensus of relevant parties or the approval of the water administrative department of the State Council.

Article 20 The management scope of embankmentd rivers includes waters, sandbanks, beaches (including cultivated land), flood discharge areas, embankments on both sides of the strait and dike protection areas.

The scope of river management without dikes shall be determined according to the historical maximum flood level or design flood level.

The specific scope of river course management shall be stipulated by the local people's governments at or above the county level.

Twenty-first within the scope of river management, the use of water and land should meet the requirements of flood, water transport and shipping; The utilization of tidal flats shall be planned by the river authorities in conjunction with land management and other relevant departments, and implemented after being approved by the local people's governments at or above the county level.
