Talk:Floodplain

message: *See discussion at Talk:Flood plain. -- Cuppysfriend 16:26, 9 May 200 clear cut to everyone which term should remain, but looking at institutions and individuals from across the English-speaking world, "floodplain" seems to be the more widely accepted form, while "flood plain" appears to be moving towards disuse (which seems to be the trend with compound nouns that become commonly accepted). And so I am now merging the two here. Daniel Collins 03:33, 14 November 2006 (UTC)
thread_title: Proposed merger with [[Flood plain]]

message: Please look at my sandbox draft of a reconstructed version of this article at User:Cuppysfriend/sandbox.  I've rearranged the text, added different, more descriptive pictures and a reference.  It's still too focused on the U.S., but it might make a good foundation to build on.  Most of the current changes are in the subsections of "Formation" and "Physical geography."  Expansion of the description of the U.S. flood insurance program as a means of restricting floodplain development would be good. -- Cuppysfriend 00:50, 21 November 2006 (UTC)
replies: text: Great work! (I was fearing re-writing the article.) Also, excellent array of images. The article's accreted enough material to trigger an avulsion to the new channel. Daniel Collins 04:32, 21 November 2006 (UTC)
replies: text: Done! (And, of course, open to further revision.) Kept older images and "globalise" template.  -- Cuppysfriend 19:19, 21 November 2006 (UTC)
thread_title: Reconstructed article

message: Deltas are aggradational but they're not described as floodplains as far as I know. Daniel Collins 00:29, 22 November 2006 (UTC)
replies: text: Hmmm...Maybe that's an artifact of the 1911 EB text.  Deltas obviously have river channels and experience flooding.  How should we recast that language?  Meantime, I'll delete the Nile Delta image.  Don't want to mislead anyone.  -- Cuppysfriend 19:45, 22 November 2006 (UTC)
replies: text: Yep...that's from the 1911 EB, all right.  Again, should we edit it or delete it? -- Cuppysfriend 19:53, 22 November 2006 (UTC)
replies: text: It's a gray area. From my perspective it is more valuable to separate floodplains from deltas from alluvial fans. While all experience flows that overtop the main channels, where the water overtops may not be well described by a plain. I think of floodplains as constrained in some way, while deltas and alluvial fans are not. I'm not sure if there is a concrete official position. Daniel Collins 22:50, 22 November 2006 (UTC)
replies: text: If this helps, it is from the Glossary of Geology, pub. by the Amer. Geol. Institute: flood plain: (a) The surface or strip of relatively smooth land adjacent to a river channel, constructed (or in the process of being constructed) by the present riverin its existing regimen and covered with water when the river overflows its banks at times of high water. It is built of alluvium carried by the river during floods and deposited in the sluggish waterbeyond the influence of the swiftest current. A river has one flood plain and may have one or more terraces representing abandoned flood plains. (b) Any flat or nearly flat, usually dry lowland that borders a stream and that may be covered by its waters at flood stages; the land, beyond a stream channel, described by the perimeter of the maximum probable flood.  Also spelled floodplain; flood-plain.  If it doesn't help, ignore it! :) To me, a delta is not a floodplain, even if it may be relatively flat; its sediments may be quite different (often coarser than the muds typical of a floodplain; yes, I know both are found in both), and geologically a delta may often be (partly) submarine and thus not directly related to river processes.

replies: text: Thank you, DC, and also you, GG, my fellow IU alum.  How about a section or subsection that spells out the distinctions you've noted, with appropriate reference to the G of G?  You guys are the pros, so why don't one of you do it?  I'm just the bumbling, well-intentioned layperson who drew the wrong conclusion from the 1911 EB language...and I don't happen to have a copy of the G of G handy for specific page reference.  Also, did I get the business about "aggradation and planation" right in the Laramie River photo caption?  Feel free to edit anything I wrote that you think is off the mark.

thread_title: A little change

message: I've edited the section on US floodplain regulation a bit.  
I tried to clarify what the floodplain/floodway/SFHA are, but tried to keep it fairly simple and generic, and not bog down into the minutia of doing a flood study, defining a floodway, etc. 
I've also edited the requirements for elevating structures within floodplains.  Where elevations have been determined by detailed study or estimation, the minimum federal requirement is only to elevate to the 100-year flood.  The two-foot requirement is for certain unstudied areas, and is two feet above the surrounding grade, not flood elevation.  
I hope that I've gotten the citation of the regs in a correct, or at least acceptable format.  I know there's a very terse format, but I thought slightly more verbose would actually be more useful.  I can also re-find the NFIP glossary page that I used to pop out the actual language/citations.   --Lonotter 20:49, 11 January 2007 (UTC)
