Drought Drains Lake Mead to Lowest Level

Drought Drains Lake Mead to Lowest Level | Geography Education | Scoop.it

"The largest reservoir in the U.S. falls to its lowest water level in history, Nevada State Sen. Tick Segerblom introduced a bill title and issued a press release on July 8 calling for an 'independent scientific and economic audit of the Bureau of Reclamation’s strategies for Colorado River management.'"


This week’s history-making, bad-news event at Lake Mead has already triggered lots of news stories, but almost all of these stories focus on the water supply for Las Vegas, Phoenix and California. But what about the health of the river itself?

Meandering Stream

Meandering Stream | Geography Education | Scoop.it

"I'm used to rivers that know what they're doing."

Seth Dixon's insight:

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.

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?

Where Does Your Water Come From? | Geography Education | Scoop.it

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.

The Living Bridge

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.

megan b clement's curator insight, December 16, 2013 12:38 PM

This video is so cool. It shows the indigenous people using the enviroment to the fullest. THese resourceful people do not even kill the tree when they use it to build the living bridges to cross over the rough waters. They actually have a community of living bridges that help the people to get from point a to point b safely. They keep the bridges alives by intertwinning them with one another to hold them up across the water. THe video itself is too cool, especially that people even thought of this!

Maegan Connor's curator insight, December 17, 2013 10:16 PM

This is so, so awesome.  These people have suffered at the hands of nature for generations and now they have figured out how to use nature to solve the problem.  They have constructed bridges with trees that takes hundreds of years to fully form so they pass it through their family generations to make life easier.  India endures a harrowing monsoon season with many floods and landslides every year and these bridges will help the people to carry on with their lives above the river's reach. These people indigeous to the region deserve so much credit for the innovative ways they have discovered to deal with nature in it's angriest forms.

Nathan Chasse's curator insight, April 11, 11:01 PM

This video shows how innovative people can be due to physical geography. In Northeast India, monsoon season creates raging rivers and floods which destroy the banks and wash away any normal bridges. The people of the Meghalaya province have devised a creative solution which solves both problems. By planting strangling fig plants, the roots reinforce the river banks and are then coaxed across the river creating a living bridge which can last for centuries.

Turbulence on the Mekong River

Turbulence on the Mekong River | Geography Education | 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.

It's sad that they have to use up this wild river. I'm not a big fan of environmental degradation but if that's what they're going to do I can't do anything about it.
Michelle Carvajal's curator insight, December 11, 2012 9:04 PM

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

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.

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?    

more...
Al Picozzi's curator insight, November 26, 2013 11:24 AM

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.

Tracy Galvin's curator insight, April 29, 6:17 PM

This situation with Bangkok is the same problem that New Orleans is facing. Building on lands that used to get regular deposits of silt is a bad idea. The ground not only continues to compact and essentially "sink" but the planet is covered in water that changes level regularly. Unfortunately, New Orleans has shown that levees don't really work and the earth will always reclaim the land it wants back.

Another image gallery! This one showcases the Thailand flooding. I found the first picture immediately interesting in that the highway signs are identical to our ones over here, save the difference of language. There's also just as much play as their is damage here. Many pictures show children and even older people taking the time to play around in the sudden water that floods into their city. In countries where flooding is a matter of "when" rather than "if," the citizens are often more prepared and take a less frantic approach as they know what to do. That being said, it is more rare of flooding to hit Bangkok than many other places in Thailand, so this did cause some serious disaster.

This picture shows the drainage patterns and how the water drifted in many directions and not just in a single line. Water does not stay in a perfect straight line it flows and drifts in many directions. This is what the image is showing, how this particular water flows in many directions and branches off from one stream to another.

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.

Iceland is one of my favorite countries, and the place I most want to visit and would most likely move to if I had to leave the United States. The landscape is insanely beautiful and the population is extremely small, something I enjoy as I dislike cities and a high population density. Even the capital of Iceland looks akin to a relatively average fishing town in the Northern US or Canada, and the entire country has less people in it than any given state in the US.

Why damming world's rivers is a tricky balancing act | Geography Education | Scoop.it
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.

The people that live here understand that they will have flooding every year. They're smart to build elevated roads so they have some way of transportation over flooded areas. It's weird to think that this is a normal thing for them and for us we close everything down and wait in our houses.
Elizabeth Allen's comment, December 7, 2012 12:17 AM
In an area already stricken with poverty, the floods manifest the problems. High rains and low elevations cause massive floods in areas such as Bangladesh and Nepal. Most areas do not receive aid, especially the remote areas of the villages.
Paige McClatchy's curator insight, December 14, 2013 4:55 PM

The "socio-economics of flooding" is a side of the natural disaster we don't normally think about. People most affected by floods tend to live in areas with poor infrastructure and large populations. Their displacement to cities, like Dhaka, has incredible cost. For both the family and the new place they relocate to.

Fantastic image, One thing that isn't mentioned is the potential effect that this will have an marine navigation.

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.
