River Thames (2)
Location 4
Looking at the river Thames here makes one realise how much more water flows in it compared with the Cherwell. If you wanted to know how much water flows in a river then you would need to measure the width and depth of the river (to obtain the cross- sectional area of the channel) and then multiply this value by the velocity (speed) of the flow of water. The resulting value is called the river's discharge and is usually measured in cubic metres per second (cumecs) or traditionally, million gallons per day.
Q.3) Suggest how many times greater is the discharge of the river Thames than that of the river Cherwell
Q.4) Why should the flow of the water in the Thames be considerably faster than it used to be, say in the last century ?
