Man carrying out a flow measurement in a river. River flow is a function of the water volume and velocity. It is important because it impacts water quality and the living organisms and habitats in the stream. Large, swiftly flowing rivers can receive polluting material and be little affected, whereas small streams have less capacity to dilute and degrade waste products. Photographed in the Gwendraeth Fach, Carmarthenshire, Wales, UK. | |
