采用简单移动平均法进行南宁站定点式ADCP流量平滑处理

Flow measured with H-ADCP and smoothing by moving average method at Nanning Hydrological Station

采用简单移动平均法对南宁站定点式ADCP采集的流量进行平滑处理,与原瞬时流量过程对比,平滑处理后的流量过程与水位过程相应,消除了原瞬时流量过程的锯齿波,平滑后的流量值更合理。

At Nanning Hydrological Station, smoothing of the flow data collected with H-ADCP was conducted by simple moving average method. Compared with the hydrograph of original instantaneous flow, the smoothed hydrograph corresponds to the water level change; the sawtooth wave of original hydrograph is eliminated and the flow data is more rational.
