Global Flood Hotspots
Perhaps we could add some information about specific areas at risk? This app (developed by reinsurer Swiss Re) shows 50 global flood hotspots and enables more accurate flood risk assessment on a global level http://www.swissre.com/library/Apps/The_Flood_App_for_iPad.html AliciaMontoya 20:56, 6 July 2014 (UTC)

Not-so-significant floods
169.202.5.105 18:18, 20 February 2007 (UTC) What makes a flood significant? (a) Large number of fatalities; larger number displaced (b) Really high economic impact (c) Ushered in a new way of dealing with flood hazards. And I think all of them would deserve WP entries of their own. I don't think a number of those in the article are significant enough to be included. Daniel Collins 19:02, 29 August 2006 (UTC)

Disambiguation page?
Okay, I don't know where I should bring this sort of thing up, but the link to the disambiguation page says there's no page, but there's no deletion history and there is an edit history as recent as last week, so why isn't the page showing up? I'm not sure how to fix it if it's indeed broken at all. Errick 17:45, 19 September 2006 (UTC)
 * Never mind, I think I fixed it.. or else it was a weird fluke and didn't load right or something. Don't mind me, I'm just easily confused. Errick 17:50, 19 September 2006 (UTC)
 * I agree that this needs work. Floods happen regardless of people living nearby. Development can make things worse but that's a different topic. The rest of the paragraph talks about why people build near rivers so this sentence doesn't fit in even if it is fixed. I plan to delete it. The next sentence says "Since Mesopotamia, man has built cities and communities by the sea or rivers...".  Only since Mesopotamia? Since prehistorical times seems more likely.-Crunchy Numbers 04:33, 4 October 2006 (UTC) Shin shan

Rant
this website should put a lock on all their articles its stupid letting people edtit it that means the information is not accurate!!In the Main Causes section, the first sentance says: "The main cause of floods is not geology or weather, but the distribution of human populations near water," but the third and fourth paragraphs of this section go on to describe flooding causes - ie: water overflowing stream channels and/or coastal flooding from high water conditions. I suggest that the first sentance be changed to "The main cause of flood damages is not . . . " 00:43, 27 September 2006 (UTC)
 * We wouldn't have this problem if people added inline sources. That's why the article is still Start class, actually.  Thegreatdr 00:49, 16 April 2007 (UTC)

Weather
I'm not contesting this but is flooding really a form of weather?
 * It's more geology and weathering than weather, though weather can cause floods. Wheels within wheels...  Thegreatdr (talk) 14:27, 20 November 2009 (UTC)

Adding a link
I work for the America's Most Wanted Safety Center, a new department of America's Most Wanted getting away from the capturing of criminals, and branching out to all aspects of safety. I feel a link to our post about flood safety would be appropriate and mutually beneficial, because looking to learn more about floods would benefit from a lesson in flood safety. The link is http://www.amw.com/safety/?p=33 please consider it. Jrosenfe 16:02, 22 June 2007 (UTC)


 * The link above is no more, but I think that a link to flood safety is entirely appropriate. I'll look for one if the article doesn't include one already. There's a picture in the gallery of someone driving through a flooded roadway, which one should never do...since it's frequently very difficult to determine if a roadway has been undermined enough (during a flood) to collapse. Guy1890 (talk) 01:16, 5 February 2013 (UTC)

or does the "Effects" section of this article sound like a worst-case scenario, apocalyptic, totally unlikely set of examples? We should really cut that back into shape, most floods are minor and not nearly as bad as they are described here. 206.15.234.167 (talk) 22:49, 4 February 2008 (UTC)

Suggestion for expanding article
Hi Bidgee,

thanks for pointing this page out to me. I am new to editing wikipedia.

I think a paragraph about flood modelling would be beneficial for this article. Ambiental developed a state of the art, very accurate flood modelling suite in cooperation with Cambridge University. Details are:

"FlowrouteTM is a flood modelling suite developed by Ambiental in collaboration with scientists at Cambridge University. FlowrouteTM is composed of a number of components that enable modelling of flood risk from:

* Rivers * Tidal (i.e. Storm-surge) * Surface Water * Tsunami * River/ Tidal Defence Breach * Dam Breach

FlowrouteTM is a novel, innovative approach to flood risk modelling and mapping that is used to predict depth, duration, velocity and extent of flooding. Using a coupled 1d/2d approach to flood modelling that is designed to make best use of high-resolution LiDAR topographic data to route flows around individual buildings, FlowrouteTM models all sources of flood risk more quickly, accurately and cost effectively than is currently possible elsewhere." http://www.ambiental.co.uk/flowroute-flood-modelling.html

Please consider the above for inclusion.

Bests Bodaonline (talk) 08:05, 1 July 2008 (UTC)
 * I'm sorry but the above reads like an advertisement/promotion for a product. Yes flood modeling would be good to have as part of flood prevention but should be sourced from an non-commercial site.Bidgee (talk) 08:12, 1 July 2008 (UTC)
 * I have something for you:

Flood modelling

Whilst flood modelling is a fairly recent practice, attempts to understand and manage the mechanisms at work in floodplains have been made for at least six millennia. The recent development in computational flood modelling has enabled engineers to step away from the tried and tested “hold or break” approach and its tendency to promote overly engineered structures. Various computational flood models have been developed in recent years either 1D models (flood levels measured in the channel) and 2D models (flood depth measured for the extent of the floodplain). HEC-RASTM, the Hydraulic Engineering Centre model, is currently among the most popular if only because it is available for free. Other models such as TuflowTM and FlowrouteTM, combine 1D and 2D components to derive flood depth in the floodplain. So far the focus of flood modelling has been on mapping tidal and fluvial flood events but the 2007 flood events in the UK have shifted the emphasis onto the impact of surface water flooding. Modelling consultancies are now pushed to produce more accurate representation of that threat. Bodaonline (talk) 10:19, 1 July 2008 (UTC)

Western PoV
As a random viewer of this page, I found the beginning of the "Flood management" inaccurate. The history of China, for example, was significantly about Emperors who managed to create effect flood-prevention systems. There's none of this in the History of China article either, and only a few specific references in Timeline of Chinese history. 74.85.42.110 (talk) 07:35, 17 November 2008 (UTC)

Doubt
I have one doubt, the sentence 'A storm surge, from either a tropical cyclone or an extratropical cyclone, falls within this category' is written under both the captions Estuarine as well as coastal but in which category does it belongs to ? and if it belongs to both how could that be possible   —Preceding unsigned comment added by Aadithyamd (talk • contribs) 11:24, 30 October 2010 (UTC)

There was extensive flooding the the southern part of Minnesota last fall when we got to much rain in a short part time which flooded and caused extensive damage to two small towns. — Preceding unsigned comment added by 66.44.153.11 (talk) 02:37, 25 May 2011 (UTC)

Dutch water line
A rare case of deliberate flooding might be a useful addition to the benefits section. Since the page is protected, I suggest the addition here.

- A controlled use of flooding is found in the Dutch Water Line, a series of water based defensive structures in the Netherlands. By a complex system of sluices, a ring of plains could be flooded by a shallow level of water, barring both vehicles and ships access to the economic heartland of the Netherlands.

- Should anyone with editing capabilities consider this a usefull addition, please feel free to insert it in the main article. — Preceding unsigned comment added by Onkl (talk • contribs) 08:09, 31 March 2012 (UTC)

Semi-protected edit request on 29 October 2017
I would like to add a section on dermatologic complications of wading in flood waters. Please find the text below: In a flood emergency many residents are forced to wade through flood waters to escape, rescuers are exposed to flood waters in the effort to help and some citizens choose to walk in water for recreation. These waters are laden with pathogens and chemicals and represent a significant exposure to those people. Some of the potential contaminants in the flood water include raw sewage, oil, gasoline, and household chemicals such as paints (sometimes lead based) and insecticides. A major concern is large scale, unintentional release of contaminants from industrial, Superfund, or agricultural sites (Young, Balluz & Malilay, 2004). Communicable diseases Bacterial and fungal skin infections have both been reported after exposure to floodwaters. The risk of infection is increased with traumatic injury to the skin and also in people with certain underlying conditions such as diabetes, chronic venous insufficiency and immunosuppression (Diaz, 2014). Staphylococcal and Streptococcal organisms remain the most common causes of superficial infection after a flooding event (CDC, 2005). However, exposure to floodwaters is associated with increased risk of infection from atypical bacteria such as vibrio vulnificus and mycobacterium marinum when exposed to saltwater and aeromonas when exposed to contaminated freshwater (Bandino, 2015). People with liver cirrhosis or immunosuppression are at increased risk of developing severe disease with vibrio and aeromonas infections (Bandino, Diaz). Fungal infections such as tinea corporis have also been reported especially in warm humid climates (Tempark, 2013).

Contact Dermatitis Contact dermatitis occurs when the skin comes into contact with chemicals that cause a reaction, often redness, swelling or itchiness. Flood water often contains chemicals from industries or households that can cause such a reaction, these include pesticides, bleach and detergents ( Mayo Clinic, 2017).

Traumatic injuries: Flood water consumes land that previously did not contain water. This makes it hard for residents and rescuers to see clearly where they are going, which can hide potential risks for traumatic injuries. This includes the covering of sharp objects (metals, glass, sticks), rocks and ditches, electrical hazards (down power lines) and animals that can be displaced from the flood waters (Shultz, 2017).

Other manifestations Additionally, psychological stress associated with a flooding event can lead to psycho-emotional aggravated primary skin disease, which exacerbates pre existing skin diseases such as: atopic dermatitis, alopecia areata, and psoriasis.

Prevention In systems already stressed by the natural disaster, the potential morbidity associated with skin infections or reactions can be life threatening and is, ultimately, preventable if exposure is limited and post-exposure safety measures are taken. Skin should be thoroughly cleaned and people with exposures should ensure their tetanus vaccinations are up to date.

CDC recommends: Avoid contact with flood waters if you have an open wound. Cover clean, open wounds with a waterproof bandage to reduce chance of infection. Keep open wounds as clean as possible by washing well with soap and clean water. If a wound develops redness, swelling, or oozing, seek immediate medical care.

Military inundation
The page Inundation directly refers to this page. But there is nothing about controlled Hollandic Water Line or uncontrolled Inundation of Walcheren inundation for military purposes (defensive or offensive) on this page. Personally, I think that the direct link should be broken and the Inundation wikipage should be filled in. So I'll refrain from attempting to write a section "Military inundation" on this semi-protected page. But there may have been a reason that is not known to me for putting the direct reference in the Inundation page. Please advise.--Ereunetes (talk) 19:21, 16 May 2018 (UTC)
 * I have Done the Deed: removed the redirect in Inundation and put an article in it, in conformity with the German, Norwegian and Dutch wikipedia articles. But now I can look at "What links here" I see a plethora of articles that should have linked to "Flood" in the first place and that were previously redirected, because they erroneously linked to Inundation (while actually meaning "Flood"). That comes of abusing a redirect page. In any case, I put an "about link" at the top of the new article to help people find the "Flood" page.--Ereunetes (talk) 21:42, 23 May 2018 (UTC)

Move content to here about health impacts?
There are several paragraphs about health impacts from floods at Effects_of_climate_change_on_human_health which I think should be moved to here. My reasoning is that those health impacts are relevant for all types of floods even those that are not caused by climate change, so I think they should rather be on this page than at Effects_of_climate_change_on_human_health.EMsmile (talk) 12:08, 17 February 2022 (UTC)
 * I've made the suggested change now. I've placed the new section "health effects" in between the existing sections on "primary effects" and "secondary effects" as it includes a bit of both. I think it works like this. It's useful to have the health effects bundled in one section, I think. EMsmile (talk) 15:24, 10 March 2022 (UTC)

Flood
A flood is an overflow of water[a] that submerges land that is usually dry.[1] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. 2400:1A00:B040:2A10:D900:C155:A1A0:18B7 (talk) 12:42, 3 March 2022 (UTC)

I am proposing to replace the picture in the lead with a collage of 4 images, like we have done at sustainable energy, climate change adaptation, sewage treatment and many other Wikipedia articles. The purpose would be to remove Global North bias, i.e. it's no coincidence that the picture that is currently in the lead is one of the Global North (Europe in this case).
