Deforestation drivers

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

So pretty much, the water controls rivers rather than particles controlling the river. Also, it appears that the motion and strength of the water causes rivers to bend and form in different curves. I'd like to think of it as a ball bouncing from side to side and every time it touches the border land of a river, it expands to the opposite side. However, when the water flow is hitting the side of a river, the opposite side is not getting any force from the water flow. In that case, the side that is not getting hit by the water flow slowly moves to the side that is being by the water flow causing river curves.

This interactive map is an excellent tool for researching how low-lying delta areas such as southern Mississippi have changed over recent years, and for what underlying reasons. Although human activity has been largely responsible for the loss of valuable marshland (land development, canals, levees), it's nice to know that in some cases human activity has actually helped to promote it, even if it was not originally intended to do so.

It makes you think: what other unintended consequences human actions are having on the environment in other places and on other scales?

Is very crazy that soon these land will be gone. What really makes me worry is that in a few years all these land in Louisiana will be gone, what is going to happen to all these people who is living right know in these areas? What action government will take? This is a very worrying situation.

If I lived in Louisiana, I wouldn’t settle down near the coast. 2,000 square miles will be lost in about 80 years. The water will have risen to 4.3 feet, and Louisiana has an average height of 3 feet. That leaves everything outside of the protective levees underwater in due time. Many pipelines that serve 90% of the nation’s offshore energy production and 30% of its gas and oil supply that goes to 31 different states and over 2 million people will all need to find a new place to live if this continues. Once home to 700 people south of New Orleans is now home to nearly 15 residents. The water level has already been ruining homes for people in Louisiana.  

The Art of Geography

Awesome rivers. i love a good river.

This seems like a useful tool to a degree.  But if we could actually simulate every destructive event then we would be miracle workers.  This was a sad event.  We have left such an imprint on the earth that it's starting to fight back.  We need to be more aware and careful with the one planet we have.  Climate changes are in the news more and more.  We can't ignore climate changes anymore.  

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.  

This is such a tangible way of showing things that seem abstract on a static map.

Een natuurlijk meanderende rivier

(North America topic 7)
Just like geography and history textbooks become obsolete the day they're published (thanks to Professors Dixon and Bonin for the phrase!), the same can be said for maps and icons.

This article uses the example of Louisiana's state highway signs, which show the outline of the state... well, according to data from the 1930s. While an updated sign isn't as pretty, it does bring about the truth that the landscape is changing, and on a larger scale this is true for the entire world, especially with influence from development and climate change.
However, I can relate to the other side of the argument too. Tossing the old LA symbol would toss a historical reminder of what once was. The same can be said for New Hampshire's Old Man of the Mountain road signs and license plates. I'd hate to see the profile removed, especially since what is symbolizes still lives on in the hearts of many residents and visitors, including myself.

Think

It's probably not what you think. It wasn't what I thought.....then again, I had no idea what was happening.

It's amazing to see that even though we have been on this planet for so long, there are stilll mysteries such as this. Tjis could have taken year s to solve but looking at the picture in the slides at the bottom of the article, it seems like this group of scientists knew exactly how to figure this out. this all happens becasue of geography and where these rocks are in the world that make them move around. Iis in a dried up lake pond that freezes over at night to create a layer of ice strong enough to help the rocks move around at night. This discovery took 2 whole years to figure out, but was vey much worth it in the end.

Una decina di giorni fa, il 21 gennaio 2014, è franato un torrione di roccia posto sopra un'abitazione a Termeno (Tramin), in Alto Adige.

Devastati campi, attrezzature, vigneti - a Tramin si produce i famoso Traminer - e tanta paura per la famiglia del sig. Herbert Trebo che ha visto uno dei massi fermarsi a pochi metri dalla casa. 

Qui trovate un filmato che riprende dall'alto la zona, evidenziando la zona del distacco e gli effetti devastanti dei massi rotolati e del terreno franato.
