Measuring River Speed -- Page 10 of 25

Determining the velocity of a stream from top to bottom.

Converting the time for the particles to move 5.0 meters into the velocity of the stream is easy.
Keep in mind that Velocity is Distance per unit Time (V = Distance / Time). Record your answer to the nearest 0.01m/sec.

Fraction of Depth	Distance Traveled	Average Time (sec)	Velocity (= Distance / Time)
0.1 D	5.0 meters	11.9 sec	m/sec
0.4 D	5.0 m	14.2 sec	m/sec
0.6 D	5.0 m	17.2 sec	m/sec
0.8 D	5.0 m	29.7sec	m/sec
