The Aztecs had a shining city on a lake, with canals, causeways and aqueducts – until the Spanish came. Mexico City is still suffering the consequences of their bad public health decisions.
Cuba's sustainable approach to farming has protected its rivers from the kind of nutrient pollution that impairs many US waterways.
Efforts to engineer Britain's rivers over the past 75 years have only made flooding worse.
Thousands of dams across the US are aging and overdue for maintenance. Taking them down can revive rivers, restore fish runs and create new opportunities for tourism and outdoor activities.
The NSW government is soon expected to grant environmental approval to Snowy 2.0. But that process should be halted.
Over the next 50 years, the arid zone – containing the areas of true desert – is projected to expand well into the Murray-Darling Basin and almost entirely envelope the Lake Eyre Basin.
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.

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.
