Outline of Final Research Achievements

The power generation potential of small wind turbines using river winds is estimated in this study. Theoretical equations indicates that strong winds dominate around the Hidga-gawa riverside area in the V-shaped straight mountain valley in Hagiwara, Gero City, Gifu Prefecture. Observations and simulations suggests that downward slope winds are strong in a clear early morning. The 10-min wind speed at the same level in the riverside area is approximately 1.5 times larger than that in the landside area, when the mean wind direction is along the river flow. It is estimated that the generation potential by small wind powers in the riverside area may be more than twice that in the landside area.
