Rivers are shaped by storms, floods, humans and… aquatic invertebrates.
The salt in the sea has built up over billions of years – but it wouldn’t have got there without freshwater rivers and streams.
Big storms with lots of flooding, like hurricanes Dorian and Maria, actually restore the Caribbean’s delicate balance between native and nonnative fish species, new research finds.
At a time when storms are becoming more frequent and severe, relying on levees for flood control can create as many problems as it solves.
Western states adopted a 7-year plan in May 2019 to manage low water levels in the Colorado River. Now they need to look farther ahead and accept that there will be less water far into the future.
It’s not just the ocean we need to worry about – plastic is accumulating in the world’s rivers, too.
Federal environment minister Sussan Ley said the environment doesn’t necessarily need all its water, whereas farmers do. But denying rivers even part of their water can harm their health in many ways.
The UK has seen drought conditions since 2018, but the flooding of June 2019 shouldn’t come as a surprise.
Thousands of hydropower dams are under construction around the world. New research shows that by cutting off sediment flow, these dams can have big ecological effects on far-off bays and deltas.
Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.
A new report predicts that one-third of the ice in the Himalayas will melt, even if we contain global warming to 1.5C. So what does that mean for the flood-prone valleys below?
Freshwater fish are suffering as drought becomes more common and severe. Whether they survive will depend on how governments manage rivers and lakes, and on taking action against climate change.
Maps can show “the big picture” to lots and lots of people in an engaging and colourful way.
Migrants are no more at risk of drowning than Australian-born swimmers but you’d never know from media reports.
The Trump administration is sharply reducing environmental protection for wetlands and streams across the US. This roundup of stories spotlights the many benefits that such water bodies provide.
The Trump administration wants to end federal protection under the Clean Water Act for many small streams and wetlands. But as a geoscientist explains, these are critical parts of large river systems.
Populations of freshwater species are in a state of deep decline. But we know why and we can reverse the trend.
A decade of bipartisan research has provided plenty of answers to the problems plaguing the Darling River.
Mass fish deaths are a blaring warning sign for the heath of the Murray Darling Basin, but just as worrying is the sight of dry areas in the Darling.
