Abstract:  
A method of cavitation peening a workpiece is provided. The method includes discharging a flow of fluid towards the workpiece at a pressure and a flow rate that facilitates forming a plurality of cavitation bubbles, monitoring a feedback parameter associated with the plurality of cavitation bubbles, and determining a peening intensity of the plurality of cavitation bubbles based at least partially on a value of the feedback parameter.
