走航式ADCP在感潮河段流量监测中的应用

Application of Walk navigation type ADCP in tidal flow monitoring

在感潮河段受上游径流、潮汐的影响,水位、流速变化较快,水文现象极为复杂。采用传统的常规测验方法验证代表线,劳动强度较大,效率低下。而走航式ADCP(声学多普勒流速剖面仪)除可以快速测量断面流量外,也可以定点(固定垂线位置)通过WinRiver软件中的命令控制ADCP定时按时长获取垂线(代表线)流速、流向,应用上述方法在北江石角站完成感潮河段的流量连续测验,取得良好的效果,从而为感潮河段流量连续监测提供了一种新的手段。

Influenced by upstream runoff and tidal in the tidal reach,water level and flow rate changed fasterly,hydrological phenomena is extremely complex.represent line used the traditional routine test methods is validated,and the intensity of labor is bigger,the efficiency is lower.But walk navigation type ADCP（acoustic doppler velocity profile instrument） not only can quickly measure section flow,also can obtain the vertical（on behalf of the line） flow rate and flow direction through the commands of the WinRiver software which controled ADCP,using the above methods,flow continuous test has been completed in the tidal reach,ShiJiao stations,beijiang river,good effect has achieved,and a new means was provided for the continuous monitoring of tidal flow section.
