How is stream discharge calculated
Web3 nov. 2024 · 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 … Webrivers and streams. It does not include the groundwater flow (or subsurface runoff Q g). Since discharge is only defined in streams or rivers, water balance calculations are often performed for the catchment area upstream of the discharge measurement site, toward which it is often assumed to drain entirely.
