Artificial stream channels in the Eastern Sierra Nevada (IMAGE)
Caption
University of California, Berkeley, researchers used a network of artificial stream channels to mimic the behavior of headwater streams under present day conditions and future climate change scenarios. The outdoor stream channels allow for natural colonization of insects, algae and other nutrients. They are also equipped with sensors to monitor natural fluctuations in the temperature and dissolved oxygen levels of the water. The wooden-framed screen in the foreground prevents fish from entering the channel.
