[edit] Difference btwn Dike and Levee

What is the difference between a levee and a dike? Bastie 00:16, 15 September 2005 (UTC)

A levee can be either a natural or a manmade feature and is always a bank. A dyke, in contrast, is always manmade and can be either a bank or a ditch. 82.10.103.233 20:37, 9 February 2007 (UTC)

- or a combination of bank and ditch as in Offa's Dyke, for example. When used as a boundary marker, a dike is normally dug on the owner's propery, with one lip of the excavation adjacant to the neighbour's land. The spoil is thrown up alongside the trench, into a bank on the owner's land and a hedge is set upon the bank. The Anglo-Saxon word was díc which was pronounced with a hard c in northern English and with a soft one in southern English. In southern English, it therefore led to the modern word 'ditch' while in the Midlands and North, the same feature is a dike. When used primarily for drainage, a dike is normally a trench; the bank would keep surface water from flowing into it. From the 17th century or so, Dutch usage influenced the use of the English word, particularly in relation to the drainage works in the Netherlands. In The Fens, where some Dutch drainage engineers were employed, the bank which the Dutch would call a dijk, is normally called a 'bank' (as in Roman Bank for example), though place-names reveal some medieval use of the word wal(l).

The OED's earliest note of the use of the word in connection with a sea bank is from 1531 'the walles dyches bankes and other defenses by the costes of the sea'. This spelling is clearly not Dutch but southern English.

In The Fens, the silt strip left by a natural levée is known as a 'roddon' (the spelling varies). (RJP 23:35, 12 February 2007 (UTC))

[edit] Picture

This article really needs a picture of a typical Dutch dike. Okay, any dike will do, but it'd be nice to see a Dutch one since the name originates from it and it's an extremely typical thing about Dutch landscapes. --Michiel Sikma 20:27, 19 January 2006 (UTC)

Yes, the current photo of the Afsluitdijk also is incorrect. While it is named to be a dike, it really is a dam. A dike is a border between land and water, a dam is between water and water (like the dam in Amsterdam). I'll see if I have a good photo of a Dutch dike somewhere. nftaDaedalus 02:00, 18 August 2006 (UTC)

Actually, as the article says, the English word dyke doesn't come from the Dutch word - it was used in Old English.156.34.37.96 15:14, 12 February 2007 (UTC)

[edit] Merge?

I think dike should not be merged with levee, because levee, though technically a type of dike, has all sorts of associations with the word that are primarily American and dike has all sorts of associations with the word that are Dutch. Considering the fact that the Dutch dike Stelling van Amsterdam is on the World Heritage list, I think you should keep the word dike. I will post a picture of a diagram of a dike plus pump taken from one of the breaks in this Stelling van Amsterdam dikeJane 07:32, 4 March 2007 (UTC)
