The method of an earthen dam constructed fulfilled by the earth is known as the earthen dam.
The earthen dam is constructed by different layers of soil.
The layers of the soil of the earthen dam are then compacted by sheep's foot rollers, tamping rollers, heavy pneumatic tired rollers, earth-hauling equipment, or vibratory rollers.
The earthen dam is constructed as a barrier that resists water or underground streams.
These earthen dams are constructed not only for protection from floods, but also provides water for various needs to include human consumption, irrigation, industrial use, navigability, and aquaculture
The earthen dam is constructed nearly trapezoidal or trapezoidal cross-section.
There are many sizes of earthen dams is constructed. But the size of the dams depends on the requirements.
As for the high earthen dam, the height of the dam is greater than 100m.
As for the medium earthen dam, the height of the dam is lies between 50m to 100m.
And for the small earthen dam, the height of the dam is lower than 50m.
The earthen dam is constructed to apply as a barrier that resists water or underground streams.
These earthen dams are constructed not only for protection from floods, but also applied to for provides water for various needs to include human consumption, irrigation, industrial use, navigability, and aquaculture.
When we need to make an economical structure then we need to apply the earthen dam because In an earthen dam just one material is economically or locally available then a simply homogeneous section is applied.
In the earthen dam the hydropower is applied to generate the electricity.
For structural reasons, earth dams are suited to the sites where a masonry dam cannot be applied.
The earthen dam is applied to either stop or slow the amount of water in a river.
The earthen dam is constructed to use as a barrier that resists water or underground streams.
These earthen dams are constructed not only for protection from floods, but also used for provides water for various needs to include human consumption, irrigation, industrial use, navigability, and aquaculture.
When we need to make an economical structure then we used the earthen dam because In an earthen dam just one material is economically or locally available then a simply homogeneous section is used.
For structural reasons, earth dams are suited to the sites where a masonry dam cannot be used.
To either stop or slow the amount of water in a river the earthen dam is used.
The earthen dam is a good choice for sites with wide valleys.
In the earthen dam, by using hydropower is often used in conjunction with dams to generate electricity.
Hydraulic-fill Method: In this method of construction, the dam body is constructed byexcavating and transporting soils by using water. Pipes called flumes, are laid along the outer edge of the embankment. The soil materials are mixed with water and pumped into these flumes. The slush is discharged through the outlets in the flumes at suitable intervals along their lengths.
Rolled-fill Method: The embankment is constructed by placing suitable soil materials in thin layers (15 to 30 cm) and compacting them with rollers. The soil is brought to the site from burrow pits and spread by bulldozers, etc. In layers. These layers are thoroughly compacted by rollers of designed weights.
