ABSTRACT
Brushes Clough was the first stepped block spillway constructed outside of Russia and in order to find out more about prototype operation the spillway was regularly monitored for the first two years of its life. There were no significant rainfall events in this time and so to obtain hydraulic data the spillway was subjected to two sets of artificially created high flow tests. The paper gives a brief outline of the Brushes Clough spillway design along with the detailed findings of the routine monitoring and high flow test programme.
