What does water control include?

Water control and other links include the following:

1. Dredge the estuaries of reservoirs and lakes, deepen and widen the cross section of water bodies, blast rocks, remove water discharge obstacles such as sunken trees, cut and straighten, increase the slope of water flow and improve flood discharge capacity.

2. Build dikes, and build dikes and revetments along banks, lakes and reservoirs to prevent flooding.

3, river regulation, multi-Han River, sub-Han River waterway along the dam to build groins, plug branches to dry, straighten out the water flow.

4. Build barrage or movable dam, manually adjust the flow and reduce the flood peak.

5. Plant trees and grass, protect the ecological environment of the river basin, reduce surface runoff and groundwater in flood season, and reduce the source of river sediment.

6. Harness the upstream banks of rivers and reservoirs, prevent mountain collapses, landslides and mudslides, and reduce the source of river sediment.

In order to realize effective water control, a series of basic methods need to be adopted.

I. Construction of water conservancy facilities

Building water conservancy is one of the basic methods of water control. Water conservancy facilities, including reservoirs, dams and canals, can regulate water flow, store water and divide water, reduce flood pressure and protect farmland and cities from floods. The construction of water conservancy facilities needs scientific planning and reasonable design to ensure its stability and sustainable development.

Second, strengthen river dredging and smearing.

River dredging is one of the important measures for water control. For a long time, river siltation is one of the main causes of floods. Dredging can increase the channel volume, increase the flow velocity and reduce the submerged area.

Dredging methods include mechanical dredging, manual dredging and biological dredging. , need to choose the appropriate method according to the specific situation.

Third, ecological revetment construction.

Ecological revetment is a method to comprehensively control rivers and protect the ecological environment. Through vegetation planting and ecological restoration, the stability of coastline is enhanced, the erosion of beach is reduced, and the self-purification ability of rivers is improved. Ecological revetment can play the role of flood control, wind prevention and impact prevention, and also provide a good habitat for river ecosystem.

Fourth, implement measures to maintain sailors.

Soil and water conservation is one of the important links in water control. In the construction of farmland, mountains and cities, the implementation of soil and water conservation measures can reduce soil erosion and maintain the water quality and quantity of water sources. Soil and water conservation measures include vegetation coverage, terrace construction and gully control. It needs the participation and implementation of farmers and residents.
