Abstract
On the occurrence of the disaster such as earthquake and heavy rainfall in the mountain, small village is isolated from the society for the long term. As a measure for this problem, it is necessary to develop a supplying system for the emergency power using natural energy to the temporary shelter. We think that the Sabo dam with river sedimentation is available for electric generation. In this study, we investigated the waterwheel structure available for the Sabo dam with large amount of river sedimentation in order to supply the emergency power. We demonstrated the efficient form of the waterwheel, the water conduit and the ramp for stable rotation of the waterwheel. And, we showed the effectiveness of the river sedimentation controlled by the water conduit for the small hydroelectric generation.
