Short summary
The Oroville Dam flood control spillway suffered catastrophic erosion damage in February 2017. We find that seismic waves recorded by a seismometer 2 km away contain information about the flow turbulence and damage location in the spillway. We show that enhanced turbulence due to spillway damage excites louder seismic waves at a given flow rate, which can be used to detect the onset and track the migration of erosion damage. The methods we use could be used to monitor other structures or rivers.
