The difference between a dam and a dam.

Dams and dams are powerful hydraulic engineering objects. They can be built for different purposes. Let us consider in more detail what both are intended for and how the dam differs from the dam.

Definition

Dam is an elevation created artificially in the zone of a water resource and performing a protective or regulating function.

Dam

Dam is an object erected on the path of a water flow to raise the natural water level. The structure allows you to get the maximum benefit from the action of the water element.

So, each of the hydraulic structures performs its tasks. Dams are often erected to protect areas close to water from flooding. Such objects must withstand a water pressure of a certain strength. Structures running along the boundaries of reservoirs are called contour. Dams are also erected in ports to protect the water area from the action of waves and ensure the smooth movement of ships during arrival, lock and exit. Structures of this type are non-pressurized.

In addition, dams are essential elements involved in the regulation of the width of river channels, as well as in the artificial separation or connection of streams. In order for the movement of water to be carried out in the desired direction, objects are placed at a certain angle to the current. Dams that allow changing the direction of a watercourse are sometimes built only for a certain period. This applies to cases when it is necessary to temporarily divert water from the river bed due to construction work carried out in a given place.

What is the difference between a dam and a dam? It lies in the fact that the dam is not always subjected to powerful water pressure. The dam is designed for a constant head. It blocks the flow, as a result of which the water level on one side of the structure rises significantly. Dams make it possible to make initially shallow rivers suitable for navigation and timber rafting. These facilities also help solve the problems of water supply and irrigation of agricultural lands, and due to the concentration of a strong pressure at the dam, it becomes possible to use water for energy.

The difference between a dam and a dam is that the construction of the latter, as a rule, contributes to the formation of an artificial reservoir. At the same time, noticeable transformations are taking place in the river itself and adjacent territories: the flow regime becomes different, the water temperature changes, the migration of fish becomes more complicated, part of the coastal zone is flooded, and the microclimate changes in the area of ​​the construction. With the help of dams, reservoirs are also created to retain melt and rainwater in gullies and ravines. The accumulated water reserves are then used for irrigation and other purposes.
