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...
Are you sure you want to delete this scoop?
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#!
See a photo of Iguazu Falls in South America and download free wallpaper from National Geographic.
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.
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.
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.

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 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
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?
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.
