Water speed measurement refers to the process of determining the speed of water flow in rivers, streams, canals, or other bodies of water. This is typically done by using instruments such as current meters or flow meters to measure the velocity of the water at a specific point in the water body. The data collected from these measurements is important for various applications such as water resource management, flood forecasting, and environmental monitoring.

A direct measurement of the speed of light would involve measuring the time it takes for light to travel a known distance, such as using a laser and a precise timing device.
A measurement that includes both speed and direction is called velocity. Velocity is a vector quantity that describes the rate at which an object changes its position, including the speed at which it moves and the direction in which it moves.
The measurement that combines both the speed and the direction of a moving object is called velocity. Velocity is a vector quantity that includes both magnitude (speed) and direction.
It is called "speed." If the direction is also included, the measurement is "velocity."
No, Mach is a unit of speed used to measure an object's speed relative to the speed of sound in the medium through which it is traveling. For example, Mach 1 is the speed of sound.
