摘　　要：目前,国内绝大部分水库下游均为天然河道,河床几乎都为不规则断面,流速变化复杂,各类发电放水、生态放水、泄洪放水等水量均难以准确掌握。根据某水库下游天然河道断面实际情况,采用走航式雷达波测流系统开展各类放水流量测流,通过率定成果显示满足测流精度,可供类似水库下游河道测流提供借鉴。Currently,the vast majority of downstream reservoirs in China are natural river channels,with almost all riverbeds having irregular cross-sections and complex changes in flow velocity.It is difficult to accurately control the amount of water released from various sources such as power generation,ecological release,and flood discharge.Based on the actual situation of the natural river section downstream of a certain reservoir,this article uses a navigation radar wave flow measurement system to carry out various discharge flow measurements.The calibration results show that the measurement accuracy is met,which can provide reference for similar downstream river flow measurements of reservoirs.
