Why Do Rivers Curve?

LEONARDO WILD's curator insight, December 5, 8:56 AM

El agua tiene su ritmo y pulsa al fluir, gira sobre sí misma. Cuando está en su ambiente natural y se le permite fluir y crear el ambiente por el cual fluye, crea los ríos sinuosos y serpenteantes y cuando esto ocurre, allí donde su dirección de giro cambia de dirección—rotación derecha, con el reloj, hacia una rotación izquierda, contra reloj—lo cual ocurre en las rectas, suelta lo que ha estado llevando y cargando en suspensión y esta material sólido se precipita. Asimismo, cuando el agua gira sobre si misma, se enfría, haciéndose más pesada. Es este tipo de movimiento el que hace que los ríos de las planicies serpenteen, más que cualquier otra influencia que haya "suavizado" sus orillas.

 

Water has its own rhythm and pulsates while flowing, it turns over itself when allowed to. When water is in its own natural environment and is allowed to flow and create its own space, it will create the sinuous rivers and when this happens, where its vortex direction changes—rotating clockwise or counterclockwise—it will release the silt and other materials it was carrying in suspension and they will fall to the bottom. Also, as it turns over itself, water cools down, becoming heavier. It is this motion that makes the plain rivers become sinuous, more so than whatever other influence that may have "loosened" its shores.

Sally Egan's curator insight, December 7, 4:27 PM

A very siual form using simple language to explain the meandering of rivers. Applicable to the course work on Hydrosphere.

YEC Geo's curator insight, December 7, 8:15 PM

Actually a very good video.  My one quibble is with the introduction, when the narrator talks about mountain streams "carving" their gorges.  The puzzle of how small streams could possibly carve out deep bedrock canyons is an ongoing research problem, and is difficult to resolve from a gradualistic perspective.

hmm, looks like some river had a little to much
Peter Phillips's comment, October 5, 2013 7:31 PM
All rivers move. Those that have a wide, flat basin meander most. Those meanders can be even more dramatic than in this image, snaking 10's of kilometres sideways over time. Combine this action with geological upheaval and it gets even more interesting. Check out images of the Murray River in Australia from space.
Matthew DiLuglio's curator insight, December 6, 2013 11:34 AM

Lol... the first words that went through my head were h--- (heck) yeah.  David Bowie... sung by an astronaut... okay, back to Geography. I thought that the rivers reminded me of something I thought of during the talk in class about lava rock being changed into other kinds of rocks over time, and cycling around.  I thought on a larger scale, about this universe, and I have read before that people are studying different areas of space-time fabrics, trying to find origins of the Universe, and answers to other existential questions.  I suppose that if one could trace patterns of rivers, and if one could trace patterns of rocks, to find where they came from, and why/how they came where they came, then by examining the (assumedly tattered and marked) fabrics of space and time, people would be able to determine origins of everything from the beginning of what existed before all universes, and also the origins of life forms.  I enjoyed the movie Prometheus, which was directed by Sir Ridley Scott, and I had to say that I thought that the messages found on rocks in caves, as a catalyst that lead the cast to go visit an alien world that had something to do with human origins, could be very literally taken.  If there are clues in rocks, why wouldn't there be other clues, possibly in celluar components of life forms, or space and time?  Applying the idea of studying rocks and rivers and other physical geographical pursuits to the idea of applying it on a gigantic scale greatly appeals to me.  I believe that humans will find some answers that way, but I hadn't directly realized just that until we mentioned some stuff about physical geography, and glacial forces carrying and spreading out rocks, and deposits and erosion.  After all, the Milky Way has origins, so why believe that we came from the Milky Way, rather than beyond?

Seth Dixon's curator insight, December 15, 2012 12:41 PM

This article and the selected gallery is based on the free e-book "Earth as Art" which I've mentioned here before earlier.  This particular image is fantastic for teaching about geomorphology and river systems.  Students can 'see' the historical layers of a meandering stream winding it's way across the landscape.  Connecting the physical geography to human geography, analyzing the flood plains can help explain the land use and settlement patterns in this Mississippi Delta image.   

UPDATE: Here's another meandering stream image (Willamette River, Oregon) that shows the dynamism of fluvial processes quite nicely.

Turbulence on the Mekong River

Turbulence on the Mekong River | AP HUMAN GEOGRAPHY DIGITAL  STUDY: MIKE BUSARELLO | Scoop.it
The Mekong River was once a wild and primitive backwater. Today, growing demands for electricity and rapid economic growth are changing the character of what is the world's 12th-longest river.

 

Economic progress for some often entails job loss and environmental degradation for others.  The once isolated and remote Mekong is experiences some impacts of globalization with residents having mixed feelings about the prospects.

Emma Lafleur's curator insight, April 30, 2013 8:03 PM

It seems to be a theme that across the bored, people are building things that directly and negatively impact the environment and the local people. There are always two sides to the problem. On one hand, the dam can help with the development of Laos because it will bring in money, but it will also destroy the fish population and therefore many fishermen will lose their jobs and people will lose a food source. It is a difficult problem because Laos needs money because there is a lot of poverty in this rural country and the fishermen do not add a whole lot to the economy, but the people need a way to survive and make money for their families as well. It's a problem that I think will be around for generation to come.

Al Picozzi's curator insight, November 26, 2013 11:35 AM

Seems the price of modernizing will be the local economy that as existed here for centuries.  It is not a small industy either, it is according to the report a billion dollar fishing industry.  However with a growing population and a demand for electricity the river is the perfect source for this power.  This globalization, like all globalization, will help some and will hurt some.  What you have to ask yourself is will it help more than it hurts?  Will it help in the long run, over time?  For everyone involoved in globalization these answeres are never the same everywhere.

Hector Alonzo's curator insight, December 15, 9:21 PM

The Mekong river is a river that many fisherman in Laos depend on for food and income. Plans to build dams that will cause the fish to seek an alternate route to migrate upstream. Critics of the dams say that the dams will cause the fish to abandon the Mekong river and go through their neighboring rivers, leaving the residents without a source of income. Many in favor of the dams say the reverse, that building the dams will boost economy and cause the area to flourish.

Sediment Spews from New England River After Irene

Sediment Spews from New England River After Irene | AP HUMAN GEOGRAPHY DIGITAL  STUDY: MIKE BUSARELLO | Scoop.it
Nearly a week after Hurricane Irene drenched New England with rainfall in late August 2011, the Connecticut River was spewing muddy sediment into Long Island Sound and wrecking the region's farmland just before harvest.

 

The effects of the flooding in Vermont and New Hampshire graphically manifested on the downstream parts of the watershed.  Good image for showing fluvial deposition and stream load.

Nic Hardisty's comment, September 4, 2012 12:04 PM
Fantastic image, One thing that isn't mentioned is the potential effect that this will have an marine navigation. With such a massive movement of sediment, it's hard to imagine that there won't be deposits left throughout the Connecticut River and Long Island Sound. This can have a tremendous impact on boats traversing the waterways, when a foot of sediment can be the difference between safe passage and running aground.

Jake Red Dorman's curator insight, November 25, 1:24 PM

El Sire Reserve in Peru is a river that has been monitored over the last 28 years. Every time I watch this short 6 second clip, I learn something different about how this river has changed. On the bottom of the screen, just past half way, the river just takes a huge short cut and cuts over and connects to a different part of the same river. This happens on the whole river too. there are 8 or 9 huge bends and curves in the river but by the end in 2012 there are only about 3 to 4 bends and curves. For some reason the water is taking short cuts and just leaving the spaces where the water used to run through and leaving it dry.

Thailand flood reaches Bangkok

Flood waters inundating Thailand north of Bangkok since July have made the journey south and reached the capital. The disaster is responsible for 400 deaths in Thailand and neighboring Cambodia and Vietnam.

 

Too much of a good thing (water) can literally be disastrous.

Joseph Thacker 's curator insight, April 19, 1:17 PM
This flood started in northern Thailand and made its way south and affected the country’s capitol, Bangkok. When a large flood hits a country’s mega-city, it causes serious economic impacts. Also, Thailand is the world's biggest rice exporter, but the floods have destroyed over a quarter of the country's crops. Damages from this flood caused billions of dollars worth of damage.
Jessica Rieman's curator insight, April 23, 5:01 PM

This flood being record breaking it was a flood that reached from Thailand to Bangkok. Seen from the images it was long lasting and took a toll of 400 deaths from this horrible disaster.

Jake Red Dorman's curator insight, November 20, 9:15 PM

The flooding that has been going on since July, has now reached Bangkok. It is the cause to over about 400 deaths. The flooding has flooded over a quarter of Thailand's rice crops, and rice is their biggest exporter. The government has given the people a 5 day period to evacuate the area. These damages are sought to cost about 6 billion dollars. I looked at all of the pictures presented in the article and a couple of them really stood out to me. One thing that caught my eye was the animals. Along with the flood and the destruction, also comes the animals that live in the water. there are pictures of snakes and crocodiles or alligators that the people in Thailand have caught. Another picture that caught my eye was the pictures of the streets and roads. I looks like Venice out there! The streets are completely flooded and all the people have their own little rafts that they now have to call home now since their homes are destroyed from the flooding. the last photo i liked was the kid (assuming from arm size that it's a kid) carrying money in one hand while his head was fully submerged in the water. This shows to me how flooded some places were that people couldn't even touch the ground to walk, but he had to swim under water to keep the money dry for whatever he was going to purchase. Its terrible what these people are going through over in Thailand.

James Hobson's curator insight, September 29, 10:12 PM

(South America topic 3)

What a perfect photo for "National Geographic"! As is the case with many of its other cover or insert photos, it shows what many have seen before (or similar to it), includes a human element in some way, but is taken from an unusual angle or distance. As another example of the pattern I'm noticing, I took a random National Geographic off my bookshelf. The cover shows the Statue of Liberty (a well-known landmark), Manhattan skyscrapers (the human element), but as would be seen from underwater (the unusual perspective). It's something about seeing something familiar from an unfamiliar perspective that makes one stop and reimagine the scope of whatever it is they have experienced.

Since i've been to Niagara Falls in Canada this would amazing to see to do a comparison on both falls.

Displayed is a map originally produced by Derek Watkins.  This map is a fantastic combination of physical and cultural geography.  While most flowing bodies of water will be called rivers or streams, the lesser used terms (brook, fork, bayou, run, arroyo, etc.) show a striking regionalization of toponym regions.  What do these patterns indicate?  Why are in those toponyms found in those particular places?

Vintage Maps Trace the Meandering Mississippi | AP HUMAN GEOGRAPHY DIGITAL  STUDY: MIKE BUSARELLO | Scoop.it

Excellent pieces of cartography...but they highlight the fact that things we think of as fixed and immovable (rivers, mountains, etc.) are a part of incredibly dynamic systems that change.  An analogy with cultural, economic and political situations could easily be made, showing that the only constant on Earth is change.
