In this study, potential of wind power generation in the Hida-gawa riverside area is estimated by theoretical and numerical modellings with observational data. In-situ campaign observations indicate that the 10-min wind speed in the riverside area is approximately 1.5 times larger than that in the landside area. Theoretical estimation based on the conservation laws of mass, momentum and heat in a valley is in good agreement with the in-situ observations. Large eddy simulations on a slope with different roughness also can reproduce a strong wind jet above the riverside area with which is approximately 1.5 times larger than in the landside area. Rough estimations based on the knowledge obtained in this study suggests that the wind power generation potential by the riverside wind in the Hida-gawa River can achieve more than double that of the landside area.
