Abstract: Wind vector is a critical factor influencing the hydrodynamics of reservoirs. Understanding wind distribution in meandering reservoirs is essential for accurately predicting water movement and mixing processes. Hence, this study focuses on a meandering reservoir, the Ogouchi reservoir. To capture the wind pattern, weather stations were installed at five locations on the surface of the reservoir. Data was collected at 10-minute intervals and 2m above the water surface of the reservoir. The results revealed that wind direction and wind speed vary significantly across different locations. Wind speed is higher in open water areas and lower in the narrow meandering upstream sections. Moreover, wind direction follows the terrain of the reservoir.
