Utah's Great Salt Lake is shrinking

Utah's Great Salt Lake is shrinking | Ingeniería del Agua | Scoop.it
Human activity is playing a role in the dwindling size of Utah's Great Salt Lake, according to new research.While the research group acknowledged the role that climate fluctuations, such as droughts and floods, have played in the shift of the lake's water levels over time, the decrease in the lake's size is predominantly due to human causes. According to the report, the heavy reliance on consumptive water uses has reduced the lake level by 11 feet and its volume by 48 percent.

Seth Dixon's curator insight, April 6, 12:15 PM

The railroad causeway that creates the color difference between the northern and sotuhern portions of the Great Lake is as the Union Pacific plans to change the causeway; the proposed bridge would allow for the two distinct salinities to intermingle more.  Environmentally, this lake is not exceptional.  Like many lakes in dry climates with growing populations, the people are using the freshwater flow into the lakes more extensively than they have in the past.  The Great Salt Lake, the Aral Sea, Lake Chad, Lake Urmia, and the Dead Sea are all drying up.

Another great example of human activities changing the biophysical environment.

USGS Release: Water Used for Hydraulic Fracturing Varies Widely Across United States

USGS Release: Water Used for Hydraulic Fracturing Varies Widely Across United States | Ingeniería del Agua | Scoop.it

The amount of water required to hydraulically fracture oil and gas wells varies widely across the country, according to the first national-scale analysis and map of hydraulic fracturing water usage detailed in a new USGS study.

This is important for land and resource managers, because a better understanding of the volumes of water injected for hydraulic fracturing could be a key to understanding the potential for some environmental impacts.

Why Do Rivers Curve?

YEC Geo's curator insight, December 7, 2014 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.

Jason Schneider's curator insight, January 27, 2015 12:15 AM

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.

What’s the deal with Antarctica and the Arctic?

What’s the deal with Antarctica and the Arctic? | Ingeniería del Agua | Scoop.it

"Perhaps the biggest misunderstanding is that the Arctic and Antarctic are similar. One’s in the north and the other is in the south; but other than that, they’re the same, right? No, this couldn’t be more wrong. These polar opposites are literally polar opposites.
For starters, the Arctic is a small, shallow ocean surrounded by land: Eurasia, Greenland, Canada and the United States. It’s only about 5 ½ million square miles, which is five times smaller than the Atlantic and 11 times smaller than the Pacific. Antarctica, on the other hand, is a continent surrounded by the entire Southern Ocean.

This may seem like no big deal, but it makes all the difference in the world. It takes a lot of energy to change water temperature compared to what it takes to change land temperature, which means Arctic seawater isn’t as cold as the continental ice sheet covering Antarctica. So, the Arctic sea ice (frozen sea water) is about 10 feet thick, whereas the Antarctic ice sheet (compacted freshwater ice) is over a mile thick."

Flooding Risk From Climate Change, Country by Country

Flooding Risk From Climate Change, Country by Country | Ingeniería del Agua | Scoop.it
A new analysis of sea levels and flood risk around the world offers more evidence that the brunt of climate change will not be borne equally.

 

More than a quarter of Vietnam’s residents live in areas likely to be subject to regular floods by the end of the century.  Globally, eight of the 10 large countries most at risk are in Asia.  These figures are the result of a new analysis of sea levels and flood risk around the world, conducted by Climate Central and based on more detailed sea-level data than has previously been available.  The analysis offers more evidence that the countries emitting the most carbon aren’t necessarily the ones that will bear the brunt of climate change.

Edelin Espino's curator insight, December 15, 2014 5:14 PM

In this article the author discusses the risk of flooding in many different locations of the world. He claims about 2.6 percent of the world's populations. That's a big percentage considering all the people of the planet. 

Danielle Lip's curator insight, April 14, 2015 12:10 PM

Flooding is a major risk when it comes to the world we live in especially for Southeast Asia, some areas will be below sea level which shows how the the climate changes are affecting the flood risks caused by global carbon emission. A study from this article shows that eight our of ten of the largest countries will be at the risk of being flooded and below sea level. The major question is how can this carbon emissions be lower? If the carbon is lower then the sea level will rise and less countries will be at risk, this is mainly focusing on Southeast Asia. Yes, we can not change the climate changes but by keeping the land clean and taking care of the environment the flood risk and sea level change could get out of risk level. 

If the weather continues at the rate it is at then about 2.6 percent of the global population which is approximately 177 million people will be living in a place at risk of regular flooding. Flooding can cause a lot of damage to homes, crops and people physically because flooding is not just a little amount of water.

The largest country at risk with people in danger from the map is China, I liked the way this map worked because you can see from the boxes how many people are going to be affected by the flooding. Instead of just having numbers, giving a better visual for people with the boxes and their sizes.

Lora Tortolani's curator insight, April 20, 2015 9:24 PM

It's like watching the land on Earth change right in front of our eyes.  According to this map, if global carbon emissions stay as they currently are and sea levels can be affected about as much as expected, 2.6 million people of the global population will live in a high risk flood zone; this wipes out 177 million people!

Aigua i energia, inseparables i imprescindibles #DiaMundialAigua - banc d'energia

Aigua i energia, inseparables i imprescindibles #DiaMundialAigua - banc d'energia | Ingeniería del Agua | Scoop.it

Aigua i energia estan estretament relacionades. De fet, són dues condicions necessàries per a la nostra vida.


Totes les fonts d’energia necessiten l’aigua en els seus processos de producció, i per poder gaudir d’aigua per a consum humà (de reg també) cal utilitzar energia per dessalar-la, potabilitzar-la, bombejar-la, transportar-la i/o depurar-la. 


El binomi aigua i energia és clau també per a la sostenibilitat ambiental, econòmica i social, perquè l’ús i abús dels recursos aigua i energia tenen impactes econòmics (omnipresents), ambientals i socials: emissions de gasos d’efecte hivernacle en la generació i ús de l’energia, canvi d’usos del territori per la gestió de l’aigua, estrès hídric del territori per sobreús dels recursos naturals, …

Se dan casos de visualización curiosa de la confluencia entre ríos, dónde se observa una mezcla muy lenta entre sus aguas.  

 

Este fenómeno se da especialmente cuando el gradiente hidráulico entre ambos ríos es bajo (es decir, fluyen casi al mismo nivel de lámina de agua) y las propiedades de las dos corrientes son muy diferentes.
