Hurricanes frequently move inland in the southeast US, causing widespread river flooding, but emergency plans focus on protecting people in coastal communities.

Today, many Australian urbanites see rivers as little more than picturesque places for a paddle. But in the colonial era, rivers served as highways, drinking sources, sewers, and routes to discovery.
Widespread flooding in North Carolina from Hurricane Florence shows the need for better advance planning in inland areas of the south and mid-Atlantic, especially near rivers.
Hurricanes in the southern US have caused widespread damage inland in recent decades, mainly through river flooding. But evacuations and stormproofing focus almost entirely on keeping people safe on the coasts.
Planning for rivers is one thing, but implementation is another as urbanisation and population growth increases.
Increased use of renewable energies could help curb climate change, but the water required for their production has dispossessed rural Guatemalans.
When a dam comes down this fall, a team of scientists will be there to track the environmental changes.
Uncontrolled growth at the expense of the environment will severely exacerbate the impacts of climate change. As shown with tragic floods in India, our cities are not prepared for extreme events.
Riparian zones are meant to be a vital part of Nairobi’s drainage system, but they’ve been built on.
The results of phytoremediation are remarkable.
Rivers are natural boundaries for evolving populations. But scientists don’t agree whether they create new species or just help maintain them. Research using birds’ molecular clocks provides some answers.
The new Martuwarra Fitzroy River Council aims to overcome a management problem faced by many traditional owners: the fact that major rivers flow through lands home to many different groups and languages.
Indigenous water rights have been overlooked for a very long time. A bipartisan agreement on the Murray Darling Basin Plan may change that.
How to cut down on toxic chemicals found in common household products.
The Murray-Darling Basin Plan has been politically fraught and mired in scandal. But environmental monitoring suggests that the health of the rivers is indeed improving – even if it will take decades.
Indigenous communities lived in the Amazon for thousands of years without chopping down their forests.
Recent research shows that US rivers are becoming saltier and more alkaline. Salt pollution threatens drinking water supplies and freshwater ecosystems, but there is no broad system for regulating it.
We think of Canada as a water-rich country, but we are not immune to water shortages or disasters. With some advance planning, Canada can avoid a water catastrophe.
Groundwater is out of sight, but it shouldn’t be out of mind. As cities struggle to cope with drought, we should remember that our largest stocks of water are hidden deep underground.
It was the Seine’s rise and fall, in response to heavy rain, that inspired our current understanding of river systems.
