Abstract
A system for determining a measurement of a discharge of a streamflow in open channel conditions using a velocity-area technique featuring a signal processor configured to receive ADCP measurement signaling containing information about ADCP measurements taken in conjunction with the streamflow, GPS signaling containing information about GPS readings in conjunction with ADCP measurements, and signaling containing information about a projection or virtual tag line using two (2) Global Position System (GPS) locations having start and end latitudes and longitudes at a measurement site in a hydrographic operation for a measurement of a discharge in open channel conditions, and an instantaneous GPS position for a station; and determine control signaling containing information to take the ADCP measurements and the GPS readings in conjunction with the ADCP measurements, as well as corresponding signaling containing information about the measurement of the discharge of the streamflow, based upon a respective distance between each station in relation to the projection or virtual tag line, as well as ADCP signaling and the GPS signaling received, using Differential Global Position System (DGP…
