ADCP在感潮水文站的使用

感潮水文站河流自然流态在潮水涨、落的影响下,顺逆变化,给流量测验带来很大影响。传统流速仪测量方法,测次多,误差大,为此采用声学多普勒流速剖面仪（ADCP）进行流速和流量的测量。比较了传统流速仪与ADCP测流的优缺点,介绍了ADCP的测量原理、安装、使用,详细分析了ADCP流速、流量比测和率定,并进行评定,以探索定点式ADCP测法在感潮水文站进行潮流量测验的可行性。黄屋屯水文站使用结果说明ADCP比较适用于感潮水文站的流量测验。

Application of ADCP at Tidal Gauging Station

Ebb and flow of tides cause changes in the natural flow regime of the river where the gauging stations are located at, which in turn gives a great impact on discharge measurement. Because discharge measurement by traditional current meter have disadvantages of more measurement times and big error, ADCP is used for velocity and discharge measurement. The paper discusses the feasibility of tide discharge measurement by ADCP flxed-point measurements. Firstly, the paper makes a comparison of advantages and disa...
