Discharge calculation
|
|
Derived from the average velocity and the local bathymetric profile, or using the "Index velocity" method, where discharge is referenced to the water level using a number of calibration measurements. Discharge may be calculated from EasyQ data, or by using an EasyV with an external water level sensor.
