Fish, frogs, turtles and platypus at major risk of extinction following the bushfires. So why aren't they getting much attention?
Dams built to hold enormous quantities of toxic mining waste have a long history of spills. Decisions in the Pacific Northwest threaten three free-flowing rivers there.
Coming to a river catchment near you: a rodent crack team ready to reduce flooding and boost biodiversity.
The water that replenishes groundwater, rivers and lakes is under threat from climate change, pollution and aging infrastructure.
Mayflies and stone flies are extremely vulnerable to water pollution, which has implications for the larger food chain.
The Victorians placed rivers in underground culverts to contain the smell and create new land for buildings.
Research has found plastic in snails in Nigerian rivers -- another sign that the country needs to manage its waste better.
The ‘New Bradfield’ scheme seeks to revive a nation-building ethos supposedly stifled by bureaucratic inertia. But there are good reasons the scheme never became a reality.
It's imperative that we understand what creates and sustains the delta for the future management of the system.
Sea levels are rising, while deltas are being starved of sediment by upstream dams.
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.
