Abstract

It may be useful to put upon record a few observations
upon the late flood in the River Derwent.
Residents in the valley above New Norfolk say that the
flood of the 23rd of last month was higher than any seen
since the great flood of 1863.
I should say that at the
height of the flood on the 23rd September about nine
million tons of water were passing every hour, about 21
times the mean hourly flow of 430,000 tons.
