Velocity

– Measure the time it takes an object such as an orange to travel 10m downstream. There should be a few meters of acceleration before the 10m start. Speed is then calculated distance (10m)/Time (How long it took the orange to travel the 10m)

Width

– A tape measure should be pulled tight from bankful to bankful height and the distance measured to provide the width of the river

Depth

Holding the tape measure taught across the bankful width a meter rule should be used to measure the distance from the tape to the bed of the river (channel depth) - You can also measure the amount of water in the river using the meter rule to measure

Gradient

– A clinometer should be used with a set of ranging rods. The clinometer should be lined up at a set point on the ranging rod and then pointed towards the same point on a second rod. The incline/decline can then be read from the clinometer to give gr
