Article alerts

This is a notice to let you know about Article alerts, a fully-automated subscription-based news delivery system designed to notify WikiProjects and Taskforces when articles are entering Articles for deletion, Requests for comment, Peer review and other workflows (full list). The reports are updated on a daily basis, and provide brief summaries of what happened, with relevant links to discussion or results when possible. A certain degree of customization is available; WikiProjects and Taskforces can choose which workflows to include, have individual reports generated for each workflow, have deletion discussion transcluded on the reports, and so on. An example of a customized report can be found here.

If you are already subscribed to Article Alerts, it is now easier to report bugs and request new features. We are also in the process of implementing a "news system", which would let projects know about ongoing discussions on a wikipedia-wide level, and other things of interest. The developers also note that some subscribing WikiProjects and Taskforces use the display=none parameter, but forget to give a link to their alert page. Your alert page should be located at "Wikipedia:PROJECT-OR-TASKFORCE-HOMEPAGE/Article alerts". Questions and feedback should be left at Wikipedia talk:Article alerts.

RFC on coordinates in highway articles

There is currently a discussion taking place at WT:HWY regarding the potential use of coordinates in highway articles. Your input is welcomed. --Rschen7754 01:41, 26 December 2011 (UTC)

Geobox up for deletion

The Geobox template, which is used in all but one river GA with a box template, and in all river FAs (41 of 43 river FAs and GAs), is up for deletion. You may be interested in commenting for or against its deletion at Wikipedia:Templates_for_discussion/Log/2012_January_3#Template:Geobox. Thanks, Ruhrfisch _><>°^° 05:06, 6 January 2012 (UTC)

Estimate

How many rivers are there in the world? emijrp (talk) 13:03, 10 January 2012 (UTC)

I think that must depend on how river is defined. What are the determining limits? Length? Discharge? Strahler number? The word "river" in its name? A table in Rivers of the United States: Volume II, Chemical and Physical Characteristics lists the number of "river channels of various sizes" in the United States (but not the whole world). The sizes correspond to the Strahler numbers, 1 for little ones averaging only 1.61 kilometres (1.00 mi) in length and 10 for the biggest one, the Mississippi, listed in the table at 2,896.82 kilometres (1,800.00 mi). The Mississippi is the only 10 in the United States, but there are 1,570,000 of the little ones. I can tell you what the total is for the United States, according to this source, if you can tell me which Strahler numbers are of interest. Finetooth (talk) 18:18, 10 January 2012 (UTC)

If you can tell me all Strahler numbers, it would be great. Thanks. emijrp (talk) 19:48, 10 January 2012 (UTC)

Order 1 = 1,570,000; Order 2 = 350,000; Order 3 = 80,000; Order 4 = 18,000; Order 5 = 4,200; Order 6 = 950; Order 7 = 200; Order 8 = 41; Order 9 = 8; Order 10 = 1. Bibliographic details about the edition of the book I'm quoting are here. The table is on page 17, and it is sourced to Fluvial Processes in Geomorphology by Leopold, Wolman, and Miller (1964), published by W.H. Freeman and Company. Hope this helps. Finetooth (talk) 21:54, 10 January 2012 (UTC)

Thanks. Does Order 1 include from 1 to 10, Order 2 from 2 to 10, etc, or are disjoint sets? emijrp (talk) 21:13, 11 January 2012 (UTC)

Disjoint sets, I would say. That is, even though the path of a drop of water that reaches the mouth of the Mississippi River, for example, might be traced upstream via smaller and smaller tributaries to the source of a #1 headwaters stream, the #10 designation applies only to the lowermost segment of the Mississippi and not to any other segment in the Mississippi watershed. In the Strahler system, a #10 segment begins at the confluence of two #9s, which in the case of the Mississippi would be the lower Missouri River segment (as I recall from looking it up a year or so ago) and the Mississippi River segment that ends at the confluence with the Missouri. Main stem has a more complete explanation. Finetooth (talk) 03:00, 12 January 2012 (UTC)

Another thought: The total number of segments is bigger than the total number of rivers even if rivers is broadly defined to include small tributaries. I think the numbers are interesting, but they don't really answer your original question. Finetooth (talk) 07:07, 12 January 2012 (UTC)

New linear geolocationing system

Over at Wikiproject:Highways we've discovered a nifty way of displaying data onto mapping services that I believe will be a large benefit to your project. By using google earth, qgis, or similar software, you can draw lines onto the globe. These can be saved as a kml file, and the contents of that kml file can be used to, in place of or alongside the current {{coord}} system, display a shape or line on the Earth. I believe this group can benefit greatly from this as it can be used to trace the actual path of a river, as opposed to just marking the mouth or source.

We're still trying to work out the finer details on how to proceed with this new discovery, so if anybody is interested check out the talk page of WikiProject Highways. Cheers, - ʄɭoʏɗiaɲ ^τ _¢ 15:06, 7 February 2012 (UTC)

The above, should it ever become viable, should not be used "in place of… the current {{coord}} system", since it offers none of the functionality of that template, for identifying, locating, and producing KML (etc) of points of interest. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:45, 7 February 2012 (UTC)

Keep the discussion at the Highway talk page, where I am directing people, instead of trying to interject your POV before they get there. You are wrong, by the way, it can offer all of the functionality plus much more. - ʄɭoʏɗiaɲ ^τ _¢ 14:30, 8 February 2012 (UTC)

You don't get to dictate where discussion happens. Please explain how the new system will produce a set of ten KML PoIs for, say, a river with ten confluences; and how it will enable a user to locate view such point, on a map centred on that point, with single mouseover; or find photographs near to it. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:18, 8 February 2012 (UTC)

Elsewhere, you just said "coord is far more appropriate for point-based topics". QED. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:54, 9 February 2012 (UTC)

The path of a river consists of an infinite number of points. In geometry, we call this phenomena a line. - ʄɭoʏɗiaɲ ^τ _¢ 16:02, 9 February 2012 (UTC)

None of which answers my question about PoIs for a river's confluences; and current functionality relating to them. Your edit summary, "'the worm dangles on the hook, but do I take the bait?" seems to imply that you have an ulterior motive for posting here. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:30, 9 February 2012 (UTC)

I don't know what a Pol is (a Polish person?), but I do know a river consists of more than confluences. What does a point at the meeting place of three linear bodies of water show me? Which stream is confluencing into which river? What is the direction of flow? Is this point the beginning of a new river, or the middle of one? [1] If I were to make this into a coordinate, and posted this as the confluence of a tributary of the Thames River: Which one is the Thames and which one is the river that is joining in (the tributary)? Is the Thames the river from the north to the west? From the south to the north? From the west to the south? (Please, tell me with your end-all-be-all solution)

Which direction is the river flowing? I can't tell you any of this with coord, but I could tell you all of this, as well as highlighting the entire length of the river and labelling all the confluences, using KML. - ʄɭoʏɗiaɲ ^τ _¢ 16:59, 10 February 2012 (UTC)

Images

I generated list of articles about rivers, without image in infobox on enwiki, but with image on plwiki - maybe somebody will be interested (also: similar list, but with maps) Bulwersator (talk) 09:11, 10 February 2012 (UTC)

We're on the Main Page!

Take a look! Big Butte Creek was unexpectedly nominated, then featured unexpectedly fast. Cheers, LittleMountain5 14:52, 10 February 2012 (UTC)

Darn... I missed it by 45 minutes. Shann_ºn 01:23, 11 February 2012 (UTC)

The KML map link method, and tagging articles with KML missing

I'm not sure how up to speed this project is on a KML method for creating map links for linear features & outlines. Now there's a proposal to tag suitable articles to add a hidden KML missing category where a KML map link is missing. Discussion here. Please join in and/or acquaint yourself with the KML method. --Tagishsimon (talk) 00:22, 23 February 2012 (UTC)
