Calibration of a drag tilt current velocimeter for an open channel application

Water is one of the prime elements responsible for life on earth with two thirds of the earth’s surface covered by it. Managing water resources effectively can promote conservation and make the best use of our limited water resources. Having knowledge about flow information on the river networks can...
