A new way to quickly estimate climate change impacts on rivers and streams

We outline a new method that offers quick insights into how the amount of water in rivers and streams will be impacted by warmer temperatures and future precipitation change. This method yields comparable results to more conventional model-intense climate change impact studies and is faster and cheaper to implement, making it a practical alternative for those exploring future water supply changes in places with limited computational access. Using rivers and streams in the Pacific Northwest of North America as an example, we share what this new method can (and cannot) do, and highlight the steps one could take to quickly begin exploring how climate change could impact their water supply.
