FLOWRATE AND VELOCITY MEASUREMENT IN NAKDONG RIVER USING ADCP
ADCP is the equipment for flowrate measurement using the Doppler Effect that transmits supersonic waves in the fixed frequency into the water and gathers reverberations which are diffused by particles suspended without interrupting a lowing stream. The flowrate measurement using ADCP is now widely used for the measurement of surveying the flowrate by crossing the river for a dry period. This method can cut the manpower and the time down compared to velocity-area method. Consequently, many kinds of ADCPs that are suitable for various scales of the rivers have been developed. There have been many-sided analyses and studies on the consequences of measuring the velocity and flowrate by using these methods. In this study, the RIO Grande ADCP of RDI Co. is applied for measuring the flowrate in Seonakdong River. The characteristics of velocity and flowrate data using ADCP, which is measured by employing a wireless controlled small boat equipped with ADCP, are compared with the result of the velocity-area method on the Seonakdong River. Seonakdong River is reservoir like river which blocked with upstream Daejeo water-gate and downstream Noksan water-gate. It has little flowrate in ordinary times, however, it has the maximum 250 CMS record of the flowrate during the water gate opening.
