Fish passage with stacked boulders

Fish passage with stacked boulders was installed at drop structure in Rusha river of Shiretoko Peninsula, Hokkaido by Youichi Yasuda. The averaged size of bouders is 60 cm. In this case, the stacked boulders without concrete were installed as a temporary installation. The stacked construction is very important for the stability of boulders.
