摘　　要：瑞谱型相控阵声学多普勒剖面仪是一款新型的走航式流量测量仪器,其在工作过程中可同步测量水深和流速,具有体积小、精度高、自动化程度高、安装使用便捷的特点,适用于不同水深和水流条件。在黄河宁夏四排口游荡型河道沙质河床裁弯取直工程截流施工期间,利用该仪器开展了龙口断面进占合龙、上下游河势变化和引河内流速、流量、断面等要素的水文监测及资料分析,为实现黄河宁夏四排口河段成功截流提供了有力的技术支撑,监测成果满足设计、施工和监理的需求,积累了在游荡型河道沙质河床上截流期水文监测的经验。Rayleigh spectrum phased array acoustic Doppler profiler is a new type of navigation flow measurement instrument. It can measure the depth and velocity of water synchronously in the process of work. It has the characteristics of small volume,high precision,high automation,easy installation and use,and is suitable for different water depths and flow conditions. During the closure construction period of the wandering sandy river bed cutting and straightening project in Ningxia section of the Yellow River,the instrument was used to carry out the hydrological monitoring and data analysis of the factors such as entering and closing of the Longkou section,the variation of river regime in the upper and lower reaches and the velocity,discharge and section in the diversion channel,which provided strong technical support for the successful closure of Sipaikou section of the Yellow River in Ningxia. The monitoring results had met the requirements of design,construction and monitoring needs and accumulated the experiences on hydrological monitoring during river closure of the wandering sandy channel.
