We then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods\u2014information that is essential for management of rivers and water supplies. We also use downscaled climate projections and watershed models to predict changes in flow and tree growth resulting from human-induced climate change. We have pioneered the use of cottonwood, a dominant riparian species, for tree ring analysis; this is a significant advance in arid regions where old trees of other species are scarce. Ongoing studies focus on rivers of the Upper Missouri Basin and the Tarim River in China."
