AN ADVANCED DISCHARGE MEASUREMENT TECHNIQUE: REAL-TIME AUTOMATIC DISCHARGE ACQUISITION REMOTE-CONTROL SYSTEM USING ACOUSTIC DOPPLER VELOCITY METERS
Real-time Automatic Discharge Acquisition Remote-control System (RADARS) has been invented to measure accurate and continuous discharge automatically without man-power especially in a tide-affected region. The RADARS is based on the 2-D non-dimensional velocity distribution by entropy concept proposed by Chiu (1988, 1989). The estimated maximum velocity can be obtained by the linear regression analysis between the measured velocity and the non-dimensional velocity for all measured points of H-ADCP. Therefore the real velocity distribution can be estimated by applying the estimated maximum velocity to the non-dimensional distribution. Acoustic Doppler Current Profiler (ADCP) discharge measurements have been made by moving the ADCP across the cross-sections to verify the discharge obtained by the RADARS. The comparison of the discharges obtained by ADCP and the RADARDS shows a good agreement. The discharges measured by RA-DARS have a tendency to be a little bit smaller than those measured by ADCP, but show acceptable errors within 95 % confidence interval. Therefore the discharge measured by the RADARS can he regarded as valid discharge.
