Human efforts to tame the Mississippi RIver have had an unexpected bonus: they've actually reduced carbon in the atmosphere.

River flow has changed significantly in recent decades across the globe. A new study shows points the finger at climate change.

Climate change will bring river avulsion, or jumping course, farther inland, predict researchers. It could mean floods in places that haven't had to worry.

For every degree of increase in global temperature, there will be about 6 days less of ice per year on rivers that freeze, researchers say.

The path of the Nile River has remained unchanged for about 30 million years. Now scientists know why.

"If you don't know where a hippo goes, how in the world can you design a thoughtful management plan?"

A new simulation shows how changing the incentives for using and storing water could help deal with droughts while also meeting demand.

"If we want to preserve our beaches, shorelines, and rivers we need to know which areas are actually hotspots that need conserving."

A new global water map is so advanced that scientists could use them to predict which rivers are most likely to flood during heavy rainfall.

Salmon in Alaska's Bristol Bay are heading to the ocean a whole year earlier than they used to because of climate change and other fish.
