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. 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.
