The Different Types and Purposes of Dams

Dam is a structure designed to block water in the form of lakes, streams, streams or other forms of water. The dam typically includes an inlet passageway that can be raised or lowered, opened or closed to allow a variable amount of water to pass downstream or to exit the lake. The way to exit the lake through the entrance canal is called a drainage canal. The Brazos River Authority has several style dams for various purposes. First, the arch dam is made of process or cement, facing upstream.

Most dams are disposable dams, but now there are increasingly multipurpose dams. Using the newly issued world dam registry, irrigation is by far the most common purpose of the dam. In the disposable dam, 48% are for irrigation, 17% for hydroelectric power generation (power generation), 13% for water supply, 10% for flood protection, 5% for entertainment, and less than 1% for navigation It is used for maintenance. Fish Currently, the irrigated area is approximately 277 million hectares, accounting for about 18% of the world's arable land area, accounting for about 40% of crop production, accounting for about 30% of rural population. As the population increases in the coming decades, irrigation must be expanded to increase food production. It is estimated that by 2025, 80% of additional food production will need to come from irrigated areas.

In this article I will explain Earth Dam, one of the oldest Earth Dams. As a water supply pond for living water and irrigation wells, Earth Dam constitutes the largest category. Due to the different basic conditions and the nature of the different properties of the materials that can be used to build the embankment, the design and structure of the earth dam is complex. I forgot to mention important things, but understanding the potential failure of the Earth dam is important for the design and construction of the Earth dam.

Also known as earth dam, or fill dam, it is constructed as a simple dam for compressed soil. Homogeneous dams are made entirely of one material, but may contain drainage layers to collect water penetration. The partitioned earth dams have locally rich shells with different parts or areas of different materials, usually waterproof clay cores. Modern split soil embankments collect and remove water infiltration and use filtration and drainage to maintain the integrity of the downstream shell. The outdated underground earth dam construction method uses hydraulic packing to manufacture a waterproof core. Rolling dams can also be manufactured from waterproof surfaces or cores using rockfill dams. An interesting type of temporary earth dam that is occasionally used at high latitudes is a frozen core dam within which the coolant circulates through a pipe in the dam to maintain the watertight area of ​​permafrost.
