Web14 dec. 2016 · Introduction 1.1- Stream discharge Discharge is a volume of water passing across one section per unit. Generally, it’s represented as “Q”. It’s determined by the multiplication of the cross section “S” and the velocity “v”. The rate of the discharge is varies by location of the stream because of the catchment area and water lost. WebStream stage (or water level) and streamflow (or discharge) are measured at locations called streamflow gaging stations. Stage is measured and recorded continuously by electronic instruments.
