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.
