Streamflow Reconstruction over Coterminous US

Principal Investigator: David M. Meko
Funding Agency: National Science Foundation

Award Period: 09/01/00 - 08/31/03

The long version of the title is "Collaborative Research: Reconstruction of Drought and Streamflow over the Coterminous United States from Tree Rings, with Extensions into Mexico and Canada." The objective of this study is to improve the application of tree-ring data to the reconstruction of regional-scale streamflow variations. Of particular interest is improvement in accuracy of reconstruction of high-flow anomalies.

Collaborators are Connie Woodhouse (NOAA), Ed Cook (Lamont Doherty), and Manu Lall (Utah State).

Research Topics
