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. This makes the dam impervious to surface or seepage erosion. [1]

Typical earthworks include road construction, railway beds, causeways, dams, levees, canals, and berms.Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes.
If the culvert cannot pass the water volume in the stream, then the water may overflow the road embankment. This may cause significant erosion, ultimately washing out the culvert. The embankment material that is washed away can clog other structures downstream, causing them to fail as well. It can also damage crops and property.
The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil. Reinforced walls utilize horizontal layers typically of geogrids. The reinforced soil mass, along with the facing, forms the wall.
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 ...
A considerable number of early notable dams were built in that era and they are now sometimes referred to as the 'Pennines embankment' type. These dams are characterized by a slender vertical puddle clay core supported on both sides by earthfill shoulders of more heterogeneous material.
The Romans made extensive use of rubble masonry, calling it opus caementicium, because caementicium was the name given to the filling between the two revetments. The technique continued to be used over the centuries, as evidenced by the constructions of defensive walls and large works during medieval times.
