Flood flows on the Buller River were the largest of any NZ river recorded in almost a century

Niwa environmental monitoring technician Mike O’Driscoll used a radar gun from the Westport and Orowaiti bridges to measure the speed of the Buller River at its surface on July 17, the height of the recent floods.
Those measurements, coupled with surveys of the riverbed level carried out from a jet boat after the flood, provided the data for flood flow calculations.
As the bridges were being closed, the measurements showed a flow of 7640 cubic metres per second – the largest direct measurement of river flow ever completed in New Zealand.
