Satellite images show the growth of two deltas between three decades. They are being formed by sediment coming from the Atchafalaya River. According to NASA, the lobe-shaped arc of coastal loses land the size of a football every hour.

The river is the power source of the Yacyretá Dam, an 800-meter long dam that can flow 4050 cubic meters of water a second. Before construction, the river was divided by the Yacyretá and Apipé islands. Decades later, the water from the formed reservoir have them completely submerged.
There was a lot of talk about California's drought problems for many years. This is satellite image is a solid example of what happened to the Golden State from the 2000s to the mid-2010s. The deep red parts of the map represent areas that had 4 trillions gallons of water disappearing annually.
China's massive hydroelectric dam is so large it can be seen from space. During Its construction these two photos were taken at different stages — the 2000 photo shows it at riverbed completion. By 2006, The dam had taken up the entire river and the waters had already created a reservoir.
This area has a rather sad nickname — China's Sorrow — due to the massive floods that have affected the people since the 10th century. The satellite images show a good idea of how the river changes flow, exposing more of the northern point in 2009.
Photos on the ground floor of floodings are always tragic, but it is sobering to see it from a scope that shows the totality of the devastation. The 2013 photo of a monsoon in Myanmar on the left shows the Irrawaddy River at a normal size. The 2015 images show how it looked after a heavy monsoon — notice how the islands in the 2015 image are all but gone.
The Chugach Mountains is home to the Columbia Glacier, a large tidewater glacier that is in a state of fast retreat. Since 1986 it has retreated more than 20 kilometers north, exposing bedrock and losing half its thickness.
