What does the water conservancy project in the water conservancy industry mean?

Water conservancy project is a project used to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating pests and promoting benefits. Also known as water engineering. Water is an indispensable and precious resource for human production and life, but its natural state can not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, adjust and distribute water quantity and meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures, such as dams, dikes, spillways, sluices, inlets, channels, water crossings, rafts and fishways, in order to achieve their goals.

Projects for eliminating water disasters and developing and utilizing water resources. According to its service objects, it is divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, beach reclamation projects and so on. Water conservancy projects that can serve flood control, water supply, irrigation and power generation at the same time are called comprehensive utilization water conservancy projects. Water conservancy projects need to build different types of hydraulic structures, such as dams, dikes, spillways, sluices, inlets, channels, water crossings, rafts and fishways, in order to achieve their goals. Compared with other projects, water conservancy projects have the following characteristics: ① wide influence. Water conservancy project planning is an integral part of river basin planning or regional water conservancy planning. The construction of a water conservancy project will have a great impact on the environment of its surrounding areas, including advantages and disadvantages such as flooding, immersion, migration and relocation. Therefore, the planning of water conservancy projects must proceed from the overall situation of the basin or region, and make overall plans to reduce adverse effects and obtain the best economic, social and environmental effects. ② Water conservancy projects are generally large in scale, large in investment, complex in technology and long in construction period.

According to the purpose or service object, it can be divided into: flood control projects to prevent flood disasters; Irrigation and water conservancy projects or irrigation and drainage projects to prevent drought and flood disasters and serve agricultural production; Hydropower projects that convert water energy into electric energy; Waterway and port projects to improve and create shipping conditions; Urban water supply and drainage projects that serve industrial and domestic water and treat and remove sewage and rainwater; Water and soil conservation projects and environmental water conservancy projects to prevent soil erosion and water pollution and maintain ecological balance; Fishery water conservancy projects to protect and promote fishery production; Land reclamation and reclamation projects to meet the needs of industrial and agricultural production or transportation. Water conservancy projects that serve flood control, irrigation, power generation and shipping at the same time are called comprehensive utilization water conservancy projects. Water storage projects refer to reservoirs and ponds (excluding regulating reservoirs specially built for water diversion and pumping projects), which are counted by large, medium and small reservoirs and ponds respectively. Water diversion project refers to the project of taking water from rivers, lakes and other surface water bodies by gravity (excluding water storage and water lifting projects), which are calculated on a large, medium and small scale respectively. Water pumping project refers to the project of pumping water from rivers, lakes and other surface water bodies by pumping stations (excluding water storage and diversion projects), and statistics are made on large, medium and small scale respectively. Water transfer project refers to the inter-basin water transfer project between first-class water resources regions or between independent basins, and the supporting projects of water transfer project do not include storage, diversion and lifting projects. Groundwater source project refers to the well project using groundwater, which is calculated according to shallow groundwater and deep confined water respectively.

Flood control, waterlogging control, irrigation, power generation, water supply, reclamation, soil and water conservation, resettlement, water resources protection and other projects (including new construction, expansion, reconstruction, reinforcement and restoration) and their supporting and ancillary projects. It is used to control and allocate surface water and groundwater in nature, so as to achieve the purpose of killing insects and promoting profits. Also known as water engineering. Water is an indispensable and precious resource for human production and life, but its natural state can not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, adjust and distribute water quantity and meet the needs of people's life and production for water resources.
