New Article: Robust climate change adaptation for environmental flows in the Goulburn River, Australia

https://www.frontiersin.org/articles/10.3389/fenvs.2021.789206/abstract Climate change presents severe risks for the implementation and success of environmental flows worldwide. Current environmental flow assessments tend to assume climate stationarity, so there is an urgent need for robust environmental flow programs that allow adaptation to changing flow regimes due to climate change. Designing and implementing robust…
