True or false? The discharge of a river increases along its course as tributaries join it adding more water.

• True

• False

True or false? Velocity also increases along the course of a river. Even though the descent in the upper courses is steeper the lower course has the greatest velocity. The reason for this is because velocity is affected by how much water is in contact with the bed and banks. The small channel in the upper course of the river means there is more friction which means the velocity slows.

• True

• False
