Abstract

The purpose of this study is to realize effective and efficient countermeasures against reservoir sedimentation in the near future. This paper shows the case study of JPOWER’s Itoshiro Dam regarding analysis of soil production area in the relevant dam’s basin. The authors are trying to clarify the major soil production area causing reservoir sedimentation by geological expertise and Egashira Model.
