An express method for evaluating water discharge based on calculating surface water flow velocity with the use of PIV-method is considered. A procedure of measurements and an algorithm of software for processing video images of water flow are demonstrated. The results of field studies with the use of the proposed method are presented and compared with those obtained by standard procedures. The proposed method gives real-time data on water discharge in a river or canal without the need to use exp
