Explanation of terms in hydraulic engineering. The more the merrier

The term water resources is defined as a source of surface and underground freshwater that can be replenished by natural precipitation.

According to the definition of water resources in the water conservancy science and technology terminology published by the National Committee for the Examination and Approval of Scientific and Technological Terms, water resources refer to the water on the earth that has a certain quantity and usable quality that can be supplemented from nature and can be used.

Water resources, broadly speaking, refers to the planet Mercury in the hydrosphere.

Overall. It includes surface water and groundwater that are under human control and can be directly used for irrigation, power generation, water supply, shipping, and aquaculture, as well as rivers, lakes, wells, springs, Portuguese tides, harbors, and aquaculture waters.

In a narrow sense, it refers to Freshwater, which can be restored and renewed year by year. Water resources are essential for the development of the national economy.

An indispensable and important natural resource. In many parts of the world, the demand for water has exceeded the amount it can handle, and many regions are on the verge of imbalances in the use of water resources.

On Earth, water, which can be used directly or indirectly by humans, is an important part of natural resources for burial. Natural water resources include river runoff, groundwater, snow and glaciers, lake water, swamp water, and seawater. According to the water quality, it is divided into fresh water and brackish water.

With the development of science and technology, more water has been used by humans, such as desalination, artificial catalytic precipitation, and the Antarctic continent.

utilization of ice, etc.

Water resources: Water resources are water sources that are available or likely to be used, in sufficient quantity and of appropriate quality, to meet the specific needs of a place over a period of time.

Natural water resources include river runoff, groundwater, snow and glaciers, lake water, marsh cavity water, and seawater. According to the water quality, it is divided into fresh water and brackish water. With the development of science and technology, the amount of water used by human beings has increased, such as seawater desalination, artificial catalytic precipitation, and the use of Antarctic continental ice.

Due to changes in climatic conditions, the spatial and temporal distribution of various water resources is uneven, and the amount of natural water resources is not equal to the amount of available water.

Unlike other natural resources, water is a renewable resource that can be reused multiple times; and the changes in the current year and inter-annual volume, with certain cycles and laws; The form of storage and the movement process are affected by physical geographical factors and human activities.

Explanation of hydraulic engineering.

A general term for various projects to eliminate harm and rejuvenate profits, and to develop water conservancy resources. It usually refers to flood control, hydroelectric power, farmland water judgment, shipping, mu annihilation, water supply, drainage, coastal and other projects.

Decomposition of the term Interpretation of water conservancy The development of hydraulic resources and the prevention of floods and water conservancy undertakings namely; Hydraulic engineering; Water conservancy disrepair explains in detail the excavation and reconstruction of the foundation. Utilization of water resources and prevention of water hazards. "Lü's Spring and Autumn Prudence":

Dig up land and wealth, and take water conservancy. Gao inducement: "Water conservancy, irrigation."

"Since then, the interpretation of engineering has applied the theories of the natural sciences to specific branches of industrial and agricultural production, and has been a general term for the various disciplines formed. Such as:

Hydraulic Engineering, Chemical Engineering, Civil Engineering, Genetic Engineering, Systems Engineering; Also known as; Engineering; Work with larger and more complex equipment. Such as: urban reconstruction projects, Beijing-Kowloon Railway.

Explanation of water conservancy terms Hydraulic buildingsA general term for all kinds of buildings that interact with water in hydraulic engineering projects.

The term water conservancy was first seen in the "Filial Piety and Prudence" chapter in the "Lü's Spring and Autumn Period", which came out at the end of the Warring States Period, but the "water conservancy" it talks about refers to the benefits of fishing. Now it is used to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and rejuvenating profits.

In 1933, the resolution of the third annual meeting of the Chinese Hydraulic Engineering Society clearly pointed out: "The scope of water conservancy should include eight kinds of projects: flood control, drainage, irrigation, hydraulic power, waterways, water supply, sewage canals, and port engineering. The word "hydraulic" refers to the use of water, and "sewerage" refers to urban drainage.

In the second half of the 20th century, new contents such as soil and water conservation, protection of water wheel resources, environmental water conservancy, and water conservancy and fishery were added to water conservancy, and the meaning of water conservancy became more extensive.

Therefore, the term water conservancy can be summarized as: in order to meet the needs of survival and development, human society has taken various measures to control and allocate water and waters in nature to prevent and control flood and drought disasters, and to develop, utilize and protect water resources. The body of knowledge that studies the technical theories and methods of such activities and their objects is called hydraulic science.

Explanation of flood control.

flood control]

Use of embankments, walls, reservoirs, spillways, and other means to prepare for flooding Explain in detail Preparing for flooding Flood Prevention. Du Pengcheng, "In a Day of Peace," Chapter 2: "At each work site, they all asked cadres to study and arrange 'flood control' work.

The word decomposition explanation of prevention prevention á vigilance, prepare for emergency preparedness in advance: prevent. Preparedness.

Prophylaxis. Precaution (precautions, vigilance). Take precautions.

Defending is like a city (refers to strictly controlling personal desires, just like guarding the oak sail in the city of Liangshan to defend against the enemy). Prevent the slightest (stop bad things and mistakes when they just appear, so as not to develop). Guard Hong's Explanation Hong ó Big:
