Riverflow reconstruction from tree rings in southern Britain

The results are statistically significant, and the stability of the regression models is verified using independent data. The reconstructions are more reliable for low flow events; a finding which is potentially useful for water resource planning. The reconstructions indicate a possible increase in the frequency of extreme low flows over the period 1755-1859, compared to 1860-1979, which although not of conclusive statistical significance, warrants further investigation.
