WebOne method uses a flowometer to directly measure the discharge in several sections of the stream. The other method uses a floating object to calculate an average discharge … WebThe discharge is derived from the sum of the product of mean velocity, depth and width between verticals. The discharge so obtained is normally used to establish a relation between water level (stage) and streamflow. Once established, this stage-discharge relation is used to derive discharge values from records of stage at the gauging station.
WebJan 1, 2016 · In this study flow velocity measurement using video images of a float was designed to measure flood discharge during heavy rainfall. A spherical float was used to obtain video image being not distorted according to oblique angle. WebThere are 3 different steps in discharge measurement viz., velocity measurement, calculation of Cross sectional area and finally discharge calculation.
