Go with the Flow: Using Flow Experiments to Guide River Management

The recent news of a “pulse flow” in the Lower Colorado River has highlighted a steadily growing trend in freshwater conservation along “working” rivers – restoring elements of natural flow regimes. A new paper reviews such flow experiments and their effects on ecological restoration.

New Study: How Cities Can Finally Get Smart About Water

If the definition of insanity is making the same mistakes over and over, then many cities have taken a certifiable approach to securing their water supplies — and they need some radical therapy before taking the big economic, ecological and human hits that come with a permanent state of thirst.

That’s the conclusion from a new study in the journal Water Policy, whose authors compared the water supply histories of 4 cities — San Diego, Phoenix, San Antonio and Adelaide, Australia. Among the lessons learned? Urban water conservation, recycling and desalination aren’t silver bullets. In fact, the best solution may lie upstream with farmers — saving just 5-10% of agricultural irrigation in upstream watersheds could satisfy a city’s entire water needs.

Brian Richter, a senior freshwater scientist at The Nature Conservancy and the study’s lead author, told me more about what cities need to do to say on the right side of dry.
