Introduction to GPS Positioning for RiverSurveyor Stationary Live Measurements

The RiverSurveyor-M9 can be used for both the Moving Boat or Stationary discharge measurements. The stationary measurement method applies the velocity area method using either the Mid-Section or Mean-Section methods for discharge calculations. The measurement of the water depth and velocity profile at individual stations has greatly improved since the introduction of Acoustic Doppler Instruments. SonTek has gone one step further by implementing GPS in RiverSurveyor Stationary Live software to determine the station locations from GPS positioning. This method improves the measurements process, efficiency and accuracy from the traditional measuring tape or tagline methods.
