Velocity: River velocity (rate of water movement varies across a stream): measured using a flow meter.A tape measure is used to measure medium distances (between several metres to 30/50 metres).[the yellow thing used for measuring the distance in long jump] A metre rule is used for measuring short distances eg. Calipers are used to measure the width, length or height of small objects.Therefore, be sure to check that you have not missed tasks by checking for the square brackets to the right of the paper (which indicate the number of points you get).This is particularly important on pages with many tables, diagrams, graphs or maps.For example, a decibel meter may be used to measure the noise level.Also, secondary data may be used, including researching the results of traffic counts. of a course of a river or to see where the wind is coming from.A single measurement at 60% of the depth of the stream should be taken to supply a reliable average.The fastest part in the river channel is known as the Thalweg.Environmental surveys may be used to track pollution at a variety of sites.A scoring system would be devised to rate the intensity and impact of litter, noise and traffic on the surrounding area.
