摘要
Abstract
The Xinyi River is an important flood discharge channel in the Yishusi River Basin,and the Shuyang Hydrological Station is a key control station on the Xinyi River.Due to the complex cross-sectional structure and uncertain water level of the river channel,it is difficult to establish a stable single-valued relationship between the water level and discharge at Shuyang Station.Therefore,researching reliable and efficient flow estimation methods is of great significance for flood control and dispatching in the river basin.To explore the calculation method of deriving discharge from water level,based on the measured discharge data over the past 5 years,the relationship between the water level at Shuyang Station,the river channel water level drop,and the discharge was established using the fall index method.The fall index was optimized using the differential evolution algorithm.The results show that the fall index method performs well under high water level conditions at Shuyang Station,with good flow estimation accuracy.The relevant results can provide a reference for the study of water level-discharge relationship and discharge calculation in other river channels.关键词
