Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake | STEM Connections | Scoop.it

"It's difficult to comprehend the ridiculous amounts of water that have fallen in such a short time in a state that, until recently, had been in the grip of a historic drought. But one place to start would be to look at reservoir levels in the state. In the past 30 days, Texas reservoirs have gone from being 73 percent full to 82 percent full, according to data maintained by the Texas Water Development board. All told, about 8 million acre-feet of water have flowed into the state's reservoirs."

Just how much of water is 8 million acre-feet?  It's almost impossible for most people to visualize that, but this series of graphics is designed to put the scale of the recent flooding in Texas into perspective (and yes, I love that Rhode Island is almost a unit of measurement).

Where Does Your Water Come From?

Where Does Your Water Come From? | STEM Connections | 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.

Bonnie Bracey Sutton's insight:

water is a resource we all depend on. Some of my best studies were on local Chesapeake Bay issues.

I was definitely unaware of where my drinking water came from. This is nice, user-friendly map... Hopefully it gets updated regularly, as it will be interesting to see how these sources change over time.

Dramatic Confluences

Dramatic Confluences | STEM Connections | Scoop.it

"Confluences occur wherever two streams come together. If the gradient is low (i.e., nearly level) and the properties of the two streams are very different, the confluences may be characterized by a dramatic visible distinction as the mixing occurs only slowly."
