Abstract The ring widths from trees within a watershed are used to reconstruct runoff. Multivariate techniques allow calibration of spatial and temporal variation in tree-ring widths with the existing runoff records. Multiple regression is then employed to reconstruct runoff prior to existing records from the variability in growth represented by the relative widths of tree rings. Consideration is given to selection criteria for trees and watersheds and to differences in response of trees and the response of runoff to the same climatic factors. The best predictions were those that incorporate information on tree growth prior to and following the year of runoff. (Author)
