"The incredible fractal pattern rivers (now dried out) were made as they spread into the salt flats of the arid Baja California Desert in Mexico."
Who says teaching about geomorphology has to be boring? This image of a dendritic drainage pattern beautifully shows the most common spatial configuration. What makes this pattern emerge here?
Are you sure you want to delete this scoop?
Great image for drainge patterns in biophysical geography.
Describes drainage patterns in Baja California in Mexico.
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.
the beauty of our earth...
Time and time again, we're reminded of nature's beauty. It's hard to believe, but these photos of real landscapes, not abstract paintings.
Andre Ermolaev, through his photography has captured the beauty of Iceland's geomorphology. Being on the Mid-Atlantic Ridge, Iceland has abundant volcanic ash which adds rich color to the fluvial systems.

If we accept that controversial dams will continue to be built for economic benefit, how can we limit their damage on the environment?
"Of all the ways we have engineered Earth in the Anthropocene, the Age of Man, surely nothing rivals our audacious planetary-wide re-plumbing of the world's waterways. But is our control of Earth's arteries causing dangerous clots?" The human-environmental interaction theme of geography is as readily apparent in this issue as any.
Environmental degradation, seasonally high rainfall, a low elevation profile and climate change combine in a very bad way for Bangladesh. Flooding, given these geographic characteristics, is essentially a regular occurence. For a more in-depth look at these issues from the same media outlet, see: http://www.youtube.com/watch?v=Wj0iZiivYJc&feature=player_embedded#!

Beautiful image! South America's equivalent to the Niagara Falls is a place that students should see.
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?
"October 28, 2011—The White Salmon River in Washington state is flowing again as the nearly 100-year-old Condit Dam was disabled with explosives Wednesday. The reservoir draining took about 2 hours. Further demolition is scheduled in 2012."
Don't have a water table to demonstate fluvial geomorphology? This Time Lapse video demonstates deposition and erosion powerfully. This is also a useful discussion started for human and environmental interactions.
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.
This goes to show how this problem happens to many regions across Earth. What Thailand is experiencing in these photos is something that is happening in many places. Flooding and rising of water leves is increasingly becoming a problem and it becomes even more of a problem when it is ruining their rice crops that take a long time to mend and take care of.
Pakistan’s monsoon floods have devastated millions of lives, but one month on, the international response remains sluggish, raising fears of a worsening humanitarian situation.
With the strong concentration of the population living in floodplains, the seasonal monsoons will always be a major struggle for South Asia.
Pakistans monsoon floods have devastated millions and international response remains slow. They are not coming forward to provide funds and about 850,000 people live in shelters because of the flooding. Three million acres of crops were destroyed, a third cattle lost and half a million homes lost. Because so much of the population lives in the flood plains the monsoons are a constant struggle for South Asia.
The flood impact in Pakistan has already been a devastating one, and it is only going to continue as time passes. The flood has not been a center story for media coverage which has made the problem even worse. Many people do not know that Pakistan is battling a flood, so aid has not increased. Pakistanis are still recovering from a 2010 flood, which makes the current situation even more difficult. Why is the international response so small?
Water is essential to life but in such places as India, Pakistan, China, and Thailand deluges have once again caused misery. Typhoon Nesat hit the Philippines earlier this week on its way to south China.
I've linked to the Boston Globe's "The Big Picture before...it consistently is one of the best sources for geographic images around the world. This particular photo essay focuses on water-related natural disasters, and seeing the damaging is a poignant moment to get students to reflect on the human and environmental interactions, how we build and where we build.
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.
"I'm used to rivers that know what they're doing."
Even though Chris Hadfield's time on the space station is over, his twitter stream can still be a great source of images displaying the physical and human landscapes (and if you needed any more evidence that he's the coolest astronaut ever, watch his parting video singing David Bowie's Space Oddity).
This incredible image clearly demonstrates the fluvial processes that have creating and this and will continue to reshape this landscape. Meander scars, oxbow lakes, channel cutoffs, floodplains and point bars are all here in this gorgeous teaching image.

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 interactive map documents where 443 million people around the world get there water (although the United States data is by far the most extensive). Most people can't answer this question. A recent poll by The Nature Conservancy discoverd that 77% of Americans (not on private well water) don't know where their water comes from, they just drink it. This link has videos, infographics and suggestions to promote cleaner water. This is also a fabulous example of an embedded map using ArcGIS Online to share geospatial data with a wider audience.

water is a resource we all depend on. Some of my best studies were on local Chesapeake Bay issues.
In North East India just north of Bangladesh is the province of Meghalaya.
This is an astounding video that shows a (literally) natural way that local people have adapted to an incredibly flood-prone environment. The organic building materials prevent erosion and keep people in contact during times of flood. The living bridges are truly a sight to behold.

This video tells a great stroy, the passing down of informaition from generation to gernation, with hope that they will live on and use the knowlage. This reflcts flok cultre and how they value there skills and pass that infomatioon on to the younge generation. Hopfully with in time the living bridge will be finished, but how it was created will only live on with a certain few.
This is a great set of images that show coastal processes for a geomorphology or physical geography class. Pictured above is Palm Bay, Australia, which also happens to show fluvial processes as well.
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.
There must be a better way to transport items and in return save the Mekong river from being degredated. Technological innovations are affecting the life in the river as local fishermen are seeing less and less fish traveling in the river. This is impacting them in the sense that they use these fish for their survival as well as for selling. They fear that in building dams and creating advanced roads over the Mekong will change their enviroment altogether and will hinder their livelihood. This is a beautiful river and I personally feel there could be a better way but there is always something sacrficed when the government choses a location to build on. - M. Carvajal
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.
River Meanders: Red River: Oklahoma-Texas Boundary: It all comes down to ... Geography.
This natural and physical border is examined by @josephkerski.
The Thai capital, built on swampland, is slowly sinking and the floods in Bangkok could be merely a foretaste of a grim future as climate change makes its...
If 'natural' disasters are becoming more fierce and impacting human societies more, we need to ask ourselves: are the physical geographic systems shifting independently or is it human society that is causing the changes? Is it the force of the hurricanes, earthquakes, floods etc. that have intensified or is the way within which humans live on the land that make us more susceptible and vulnerable to the effects of these disasters?
Seems that sinking cities is not just a problem for Venice. As the cities grow larger and more and more land is needed, small cities that were built on unstable land are now larger. These new cities cannot be supported by the land they were originally built on. As the natural disasters occur, and we know they will, they are intensified by the fact that a city has grown and more people are there. There will always be natural disasters, but when a major flood hits and unpopulated area it is still a natural disaster just not on the same scale as hitting a city that is overpopulated or built up to a point where the land it is on just can't support it. It is the human part of the disaster that makes it much more then just a natural disaster.
This infographic is stunning in its artistry and presentation of how mountains and rivers "stack up" next to each other (Good to point out that the rivers were "straightened" for comparative purposes). The image comes from the General Atlas of the World, which was published in 1854. It contained upwards of seventy maps, reproduced from the steel engravings of noteworthy cartographers Sidney Hall and William Hughes. For the legend and more about this map see: http://io9.com/5855100/gorgeous-victorian-infographic-shows-earths-mountains-and-rivers-as-we-knew-them-over-150-years-ago
Prime minister Yingluck Shinawatra warns population to expect floods as rising waters reach capital city...
Geographic ironies....some struggle in drought while others have more water than their lands can handle.
This is a fabulous archive of some truly beautiful images of earth systems. This image of Rio Bermejo in Paraguay was described as "the river that looks like a signature."
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.
