Définition
Sens technique
Volume of water passing through a cross section of a watercourse per time unit. The flow rates of watercourses are expressed in m3/s with at least three significant figures (e.g. 1.92 m3/s, 19.2 m3/s, 192 m3/s) or, for small streams in l/s. The accuracy of a flow result depends on many factors: type of method used, careful measures, rigorous counting, influence of the ground. In hydrology, the term "flow rate or flow" is found in many expressions having a descriptive character: low water flow, fluid flow, morphogenetic flow, solid discharge rate or sediment discharge.
