A diagram showing an embankment Disbanded West Somerset Mineral Railway embankment near Gupworthy, UK Cream-colored concrete abutment marks a gap in an embankment and gives vertical support to the dark red trestle bridge, and to the fill of the bridge approach embankment. To reduce the metal cost of the bridge here it is further supported by ...
Modern zoned-earth embankments employ filter and drain zones to collect and remove seep water and preserve the integrity of the downstream shell zone. An outdated method of zoned earth dam construction used a hydraulic fill to produce a watertight core. Rolled-earth dams may also employ a watertight facing or core in the manner of a rock-fill dam.
The side of a levee in Sacramento, California. A levee (/ ˈ l ɛ v i / or / ˈ l ɛ v eɪ /), [a] [1] dike (American English), dyke (British English; see spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the banks of a river, often intended to protect against flooding of the area adjoining the river.
Most flood embankments are between 1 metre and 3 metres high. A 5-metre-high (16 ft) flood embankment is rare. [1] Modern improvements to this design include constructing an internal central core made from impermeable substance like clay or concrete, some even use metal pilings. [2] Some authorities call man-made structures levees.
Earth ditch and rampart defences on the Ipf near Bopfingen, Germany Reconstructed pfostenschlitzmauer of the oppidum at Finsterlohr, Creglingen, Germany. The composition and design of ramparts varied from the simple mounds of earth and stone, known as dump ramparts, to more complex earth and timber defences (box ramparts and timberlaced ramparts), as well as ramparts with stone revetments.

A polder (Dutch pronunciation: ⓘ) is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dikes. The three types of polder are: Land reclaimed from a body of water, such as a lake or the seabed; Flood plains separated from the sea or river by a dike
It is performed to assess the safe design of a human-made or natural slopes (e.g. embankments, road cuts, open-pit mining, excavations, landfills etc.) and the equilibrium conditions. [1] [2] Slope stability is the resistance of inclined surface to failure by sliding or collapsing. [3]
Hachures are still used today on Large Scale maps to show slopes and on British Ordnance Survey Maps and also in various countries toposheets to show Road and Railway Cutting and Embankments. On British OS Maps they have become long triangles with the short base at the top, and always pointing downwards.
