A study of more than 2,000 streams around North America found that those altered by human activity are at greater risk of flooding.

The study from the University of Waterloo analyzed the seasonal flow patterns of 2,272 streams in Canada and the U.S. and found that human-managed streams – those impacted by developments like dams, canals, or heavy urbanization – had significantly different flow patterns compared to streams in natural watersheds.

A tribute to Bill Taylor

Bill Taylor

Past and present members of the Faculty of Science community are saddened by the news that William David Taylor passed away on January 24, 2022. Bill had a long and distinguished career of service inside and outside the University of Waterloo. He will be remembered with great affection by the many professionals that he trained as students, and by the many colleagues who had the pleasure to work with him in research and administration.

Southern Ontario wetlands provide $4.2 billion worth of sediment filtration and phosphorus removal services each year, keeping our drinking water sources clean and helping to mitigate harmful and nuisance algal blooms in our lakes and rivers.

A new study from the University of Waterloo uses economic valuation to help us understand the importance of Southern Ontario’s wetlands for water filtration – particularly as these sensitive ecosystems continue to be lost by conversion to agriculture or urban development.

On November 11, the University of Waterloo is honoured to take part in the 26th UN Climate Change Conference of the Parties (COP26) in Glasgow, UK.

From October 31 – November 12, 2021, more than 190 world leaders are expected to arrive in Scotland together with tens of thousands of negotiators, government representatives, businesses and citizens for twelve days of talks aimed at accelerating action on climate change.

New research will help mining companies better understand the negative societal and environmental impacts of mine-waste disasters, known as tailings flows, and hopefully avoid them.

Researchers created a database as part of a study that presents the first global picture of the occurrence rates, behaviours and physical impacts of tailings flows, which are rapid downstream movements of mine waste following failures of tailings impoundments.
