Flooding on the Irawaddy These 2 images from the Landsat 8 satellite show the Irawaddy River in Myan

Flooding on the IrawaddyThese 2 images from the Landsat 8 satellite show the Irawaddy River in Myanmar; the upper image was taken during a normal August and the lower was taken in August of 2015.In the upper image, the Irawaddy is a classic braided stream, wandering back and forth between a number of channels with bars and islands of sediment in the gaps in-between. Heavy rains and Tropical Cylone Komen struck the country in July, causing significant flooding on this river and bringing it up to the level where it covers virtually all of the bars in the channel. You can also see that the smaller tributary channels are swollen as well.More than 100 people reportedly died in the flooding and large amounts of farmland have been lost for the year.Floods like these are natural features; in fact the bars probably testify to previous floods. When a river like this reaches flood stage, it submerges the piles of sediment in the channel and begins mobilizing that sediment. Floods help take sediment out to sea and if they are not anchored by vegetation, the bars and channels can be moved around and reconstructed in the process.-JBBImage credit: NASA/USGS/Landsathttp://earthobservatory.nasa.gov/IOTD/view.php?id=86394 -- source link
