Flood embankment Flood embankment A flood embankment is traditionally an earth wall used to shore up flood waters. Most flood embankments are between 1 metre and 3 metres high. A 5 metre high flood embankment is rare. Modern improvements to this design include constructing an internal central core made from impermeable substance like clay or concrete, some even use metal pilings. Some authorities call man-made structures levees.

River Usk Newport at Newport Wetlands. The Monmouthshire and Brecon Canal follows the Usk for most of the length of the canal. The name of the river derives from a Common Brittonic word meaning "abounding in fish" (or possibly "water"), this root also appears in other British river names such as Exe, Axe, Esk and other variants. The name is cognate with "pysg" (plural of "pysgod"), the Welsh word for fish, borrowed from Latin "piscis". The name of the river appears as "Wÿsk" on the Cambriae Typus map of 1573. The whole river has been designated a Site of Special Scientific Interest.
