The competence of a stream increases proportionally to the mathematical square of its speed (3).įigure 3. The key lays in the water speed fast water streams have a larger competence that the slower ones, despite the size of the water stream beds. By its competence: which measures the ability of a stream to transport particles according to the size of these, rather than the quantity which is carried away.Large rivers with high flow speeds have a major capacity. As larger the water that flows in the stream is, the higher its capacity to transport the sediment. By its capacity: which refers to the maximum amount of sediments that may be carried.The ability of a stream to transport particles can be described in two ways: Transportation of sediments through a water stream according to the size of particles.
