TERME PRÉFÉRENTIEL

DISCHARGE/FLOW  

DÉFINITION

  • In hydrology, discharge is the volume rate of water flow that is transported through a given cross-sectional area.(Buchanan, T.J. and Somers, W.P., 1969, Discharge Measurements at Gaging Stations: U.S. Geological Survey Techniques of Water-Resources Investigations, Book 3, Chapter A8, p. 1.)  It includes any suspended solids (e.g. sediment), dissolved chemicals (e.g. CaCO3(aq)), or biologic material (e.g. diatoms) in addition to the water itself.
