A CONSIDERATION OF THE SMALL HYDROPOWER USAGE TO PREVENT THE FLOOD FROM INLAND WATERS

Abstract

Recently, flood disasters due to local heavy rain have occurred in Japan that is caused by the passage of linear rain belt. This paper focused on the flood from inland waters (inland flooding). These flooding occurs when water flows into the region with no escape area. The purpose of this study is to make clear the reason of this type of flooding by considering the influence of connecting small channels in the areas where many inland flooding have occurred many times over the past few years. In this paper, the information acquisition method in waterways and the usage of small hydropower are presented.
