1911POV and merge with Channelization

I have just edited this article to remove the 1911POV, by quoting more recent environmental concerns, removing judgemental statements regarding flooding in China, adding computational models etc. The examples in the article are generally European ones. Channelization refers to one aspect of river engineering and is exclusively North American. Viv Hamilton 18:16, 29 July 2006 (UTC)[reply]

there seems now to be a confusion between "channelization" and "canalization". The former (AIUI) is described by a USACE project: "The intent of the project is to deepen, widen, and straighten the creek to move high volumes of water swiftly away from flood prone areas." Canalization in contrast refers to attempts to restrict flow by weirs to increase depth for navigation, power generation etc. The first term may be north American but both practices are world-wide. Is this distinction agreed? Chris55 08:55, 21 August 2007 (UTC)[reply]

merger

merge is probably not a good idea, but both articles need a LOT of work. why dont we let each evolve? i agree with Viv Hamilton that channelization is just one aspect of the huge subject of river engineering. Anlace 20:09, 28 February 2007 (UTC)[reply]

I tend to agree. I've reorganized it to distinguish the two major types of river works but there still is a considerable amount of repetition which I haven't removed and will need careful going over. Maybe the two major sections could be hived off, but at least I hope they make a bit more sense. Chris55 17:34, 22 August 2007 (UTC)[reply]

Hydromodification

Hydromodification might be considered a broader topic than River Engineering. Should hydromodification have its own page (currently there is no page on this topic), or can it find a home here in a separate section?

US EPA has issued a publication on hydromodification, and introduces the topic as follows:

Hydromodification is one of the leading sources of impairment in streams, lakes, estuaries, aquifers, and other waterbodies in the United States. Three major types of hydromodification activities: 1. channelization and channel modification 2. dams 3. streambank and shoreline erosion; change a waterbody's physical structure as well as its natural function.

National Management Measures to Control Nonpoint Source Pollution from Hydromodification U.S. EPA, July 2007

I can get a new section or page started (with help from the EPA document). Moreau1 (talk) 04:04, 29 November 2007 (UTC)[reply]

I think I would be inclined to add it here as a section, at least until the article grows sufficiently that we need to consider splitting material off Viv Hamilton 15:54, 30 November 2007 (UTC)[reply]

I've added a short paragraph in the intro about hydromodification. Another section could be added on the topic to provide more detail, however I think it would be appropriate for someone to first work on the existing sections to provide some more updated material, i.e. more on the extent and mechanisms of environmental degradation associated with hydromod. Althrough there is a section on Modern Policy (which I have added to, a bit), this article's heavy reliance on the 1911 Britannica material makes it difficult to launch into a broader discussion of the contemporary issues associated with hydromod. (Or at least, difficult for me!) Moreau1 (talk) 05:44, 9 December 2007 (UTC)[reply]

Regulation works

This is apparently a UK term. I've not seen it in US publications and have not been able to locate a clear definition. It can be a confusing term when different meanings for the words "regulations," "works" (as in "public works"), etc. appear elsewhere in the same article. Therefore I've revised the title of this section to "Regulation works (flow and depth control)." Moreau1 (talk) 05:30, 1 May 2010 (UTC)[reply]

Grammar

Even if the cut is preserved by protecting the banks, it is liable to produce changes shoals and raise the flood-level in the channel just below its termination. ...does this make sense? John Mark Wagnon (talk) 09:11, 26 June 2018 (UTC)[reply]
