How is river discharge calculated
WebSTREAM DISCHARGE MEASUREMENT (STREAM GAUGING) The discharge Q from creeks, small streams and rivers can be determined by a number of methods, four of which are discussed below. The determination of stream discharges is known as gauging and the choice of a particular method is one for the hydrologist or engineer. Web3 nov. 2024 · The discharge is nothing but a multiplication of the average velocity of flow and that of area of cross-section of water. 2. Weir Method. Various kinds of weirs are installed across the river streams to measure the discharge. The head of water over the weir crest is measured and the discharge is calculated by using the appropriate formula.
