An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi- plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core.
Embankment (earthworks), a raised bank to carry a road, railway, or canal across a low-lying or wet area Embankment dam , a dam made of mounded earth and rock Land reclamation along river banks , usually marked by roads and walkways running along it, parallel to the river, as in:
A tailings dam is typically an earth-fill embankment dam used to store tailings, which are produced during mining operations after separating the valuable fraction from the uneconomic fraction of an ore. Conventional water retention dams can serve this purpose, but due to cost, a tailings dam is more viable.
Embankment style diversion dams are constructed to counteract the force of the water pushing on the dam by building a dam with enough weight to withstand the force. Embankment dams are commonly made from materials in the surrounding area where the dam is being built. The materials generally include: sand, gravel, and rocks.
An embankment is a raised wall, bank or mound made of earth or stones, that are used to hold back water or carry a roadway. A road , railway line , or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain , the alternatives being either to have an ...
By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list. Data on volume of structure is not as easily available or reliable as data on dam height and reservoir volume.
For dam construction, two cofferdams are usually built, one upstream and one downstream of the proposed dam, after an alternative diversion tunnel or channel has been provided for the river flow to bypass the foundation area of the dam. These cofferdams are typically a conventional embankment dam of both earth- and rock-fill, but concrete or ...
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". [1] It can be constructed of earth, masonry , wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels , England, which dates from the Neolithic age. [ 2 ]
