River velocity Measuring the velocity allows us to determine the speed‚ at which the river travels. If a high quantity of rain falls close to the source of the river there will be a greater amount of water travelling down stream and as a result the volume of water will be travelling at a higher speed. In the section of the river harbourne that that this measurement was taken in a high river velocity can indicate that Harbertonford is susceptible to flooding‚ a hazard that the flood defences
