Flood embankment and protection status. 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.

Artificial lift Artificial lift Artificial lift refers to the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well (known as pump or velocity string) or by decreasing the weight of the hydrostatic column by injecting gas into the liquid some distance down the well. A newer method called Continuous Belt Transportation (CBT) uses an oil absorbing belt to extract from marginal and idle wells. Artificial lift is needed in wells when there is insufficient pressure in the
