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.

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.

Tony Aguilar's curator insight, October 13, 2013 2:56 AM

submarine canyons are a natural underwater phenomenon with no clear explainable cause. They are located in parts of the world sush as New Zealand and off the coast of Santa Monica california. These canyons at the bottom of the ocean may have been ancient rivers from before prehistoric times, and the erosion and subduction of the tectonic plates over millions of years leave the remains of channels of rivers from the past. Another theory is that they are caused by water forces that caused the sea bed to erode and make way for an actuall canyon. With the use of Sonar technology we are still discovering phenomons of the submarine world as sciene progresses. These canyons are common and are found all over the Earth and give is an understanding of what the world may have looked like long ago.

On a personal note, my very first globe and National Geographic magazines were given to me by my grandparents who noticed I had an affinity for all things geographic.  They lived just outside Yosemite Park and they made sure I explored it frequently while I was growing up so I have a soft spot for this particular national park.  My grandmother informed me that El Capitan was the largest single piece of granite on Earth and my skeptical 3rd grade mind replied, "Is that a fact or an opinion?"  Informal geographic education had a greater impact on my educational path than the formal K-12 curriculum.  Without those simple nudges, I doubt I would be a geographer today.

I find it quite facinating how the world changes. Some of the worlds most beautiful things may not be here 30 years from now. It is quite humbling that things that man builds can be taken away by Mother Nature. As the years pass the memories made will be vanished by the environment.

Interesting how the physical landscape of one country can be effected by the surrounding water that connects two different countries. To have some areas of Louisiana be overtaken by the Gulf of Mexico is astounding, seeing an area that has stayed relatively the same be wiped off the map is interesting

Matthew DiLuglio's curator insight, December 6, 2013 11:45 AM

Canyons are really cool to look at, but they also tell stories.  The various layers of rock can be dated based on crystal structures and possible organic content in sediment, and the eroded sides can be traced back to wind, or in some areas, water-based erosion patterns.  I think that shows that one does not just have to look at the rocks, but one can use their imagination to view history, and even infinite time by considering that the canyons are transient and shifting messages that are carved into rocks by the world, and the universe.  I think that where the article said people have relied on and depended on canyons, it brings to the surface more illumination of the immense convenience of humans having everything they need to survive- just on this one planet...  Food, clothes, shelter, can be created by what is around us.  It is like we were put here with resources- it sorta feels like some of the Sim games.  I do believe aliens are responsible for putting what is now known as the human species on this planet, and I do believe in the abstract yet artificial terraformation of Earth by aliens.  Canyons erode, and die away, as do humans.  I can't help but believe that they are messages from the natural universe, along with the material resource provisions that have been so widely abundant for humans on this planet.

David Ricci's comment, April 22, 2013 3:40 PM
I actually watched this video the first time we went to the computer lab in gauge just because it caught my eye. I think that this is a cool way to show different landforms and how some of the ecosystems processes work with and around them. I feel that this video encompasses geography as a whole. Seeing the way that the water falls around the mountain made in the video and where it ends up pooling is a good example of natural geography. When looking at the area the lake is now centered a viewer can see where a potential colony or group of people may live in this are. This all depends on closeness to resources such as water, arable land, and potential food supplies. All of this depends on the physical occurrences that you can see in this video. This video also helps to tie in the lesson in class about geomorphology. The creation of dremmels by glaciers, runoff from the mountains, and plate tectonics. These topics can be taught through a power point, but it really helps to see all of this created and the process it takes.
Brianna Simao's comment, April 30, 2013 10:28 PM
This is a cool way to show the different landforms and the potential use of the surrounding area. It shows us where people could migrate to and start a community and the resources it may have. It also shows the geomorphology of how the landforms were made. I agree with David when he says that these topics can be taught through a power point but to get a real understanding of how they are created and the process it takes, this is the best way to learn.

When I was a graduate student at Penn State, I was introduced to some great people and programs and I'm glad to see that the institution has continued to excel and be a leader.  You have probably heard of MOOCs (Massive Open Online Course) and been interested in seeing how this might change higher education in the future.  This MOOC is a free 5-week course designed to be an introduction to mapping, GIS and geospatial technologies so you don't need to be a specialists with a mapping background: it's for beginners.  I know that many geography teachers tell their students about GIS, but are afraid to teach with GIS because they are worried that it will be too hard.  This is an easy on-ramp to 21st century geospatial tools and any geography teacher hoping to modernize their skillset would do well to take this summer course fromthe Program of Online Geospatial Education at Penn State, taught by Dr. Anthony Robinson.  For more information on this, see this annoucement from Directions Magazine and from Penn State News.

GIS is redefining mapping skills. In 21st Century education, it is crucial that we communicate GIS literacy in our geography curriculums and classrooms. As a geography teacher it is, therefore, also crucial that I have a thorough and sound knowledge of this field. This course could strongly assist such an understanding as professional development throughout my teaching career.

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.

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.

PIRatE Lab's curator insight, April 7, 11:48 AM

There are several reasons for mudslides--some are purely a result of physical geography and others are related to land use patterns.  This last week's mudslide in Washington state was a combination of the two and although this impacts one place (see on map), it is a good teaching moment to discuss the environmental impacts of land use patterns and resource extraction projects.  As seen in this interactive, the river was cutting at the base of the hill, while loggers were clear-cutting at the top of the mountain.  Trees help prevent erosion as the roots hold the soil in place--a critical piece to the puzzle in a very rainy climate.  With $1 million worth of timber on the slope, logging companies persisted despite objections from the Department of Natural Resources and some restrictions (but in hindsight, those restrictions clearly were not enough). 

 

View the impact in ArcGIS online: Before and After Swipe, LiDAR I and II, and Imagery.

 

Questions to Consider: Other than economic worth, what other ways are there to value and evaluate the environment?  How could this landscape have been protected and managed better or was this mudslide inevitable?

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?

This video is crazy! It shows the erosion of a road during a storm. The water was supposed to run under the road and flow through a large pipe. As you can see after watching the video the road eventually erodes and then the pipe begins to bouy up and down. Later the road is completely deteriorated and the pipe ran down the river with the rest of the road.

This image tells the story of Akimiski Island's recovery after the last Ice Age, when it was covered with glaciers so large they sunk the island. The layered scarring on highlighted in the lower image was caused by waves as the island rebounded and rose along with the rising oceans as glaciers melted.

 

I wonder what forces are at work to raise the elevation of the island, possibly just decompression from the millions of pounds of pressure the island was under during the Ice Age.

Mount Dixon's landslide is due to the mountain itself being unstable. The landslide pattern is normal in retrospect to other landslides that have happened over the years. The before and after pictures are a clear depiction of the landslide path from top to bottom.
