ADCP与转子式流速仪流量测验比测分析试验研究

通过对ADCP和转子式流速仪在湖南湘潭、邵阳和桃源三站进行比测试验，根据流量比测资料，分析研究了洪水过程、走航船速、同速同断面情况、左右岸边盲区流量估算、外延盲区流速分布率定对断面流量的影响．验证了ADCP的测流精度，明确了其适用环境以及测验使用条件，得出：湖南省大多数河流适合ADCP进行流量测验，且精度满足要求。

Research on Comparative Measurement of Discharge with ADCP and Rotating Element Current Meter

Comparative measurements have been carried out in Xiangtan, Shaoyang and Taoyuan stations of Hunan Province between ADCPs and rotor type current meters. According to measuring results, the article analyzes the graph of flood, velocity of hydrometric boat, same flow rate in same cross section, discharge estimation of unmeasured areas near banks, and the impact by rating velocity distribution in extensive unmeasured areas on discharge of cross sections. As a result, precision of ADCP measurement is verified, applicable environment and required conditions are clarified. The conclusion is that, most of rivers in Hunan Province are suitable for ADCP discharge measurement, and precision is within specifications.
