Investigating Researcher (3)：
River water around salmon going againt stream it changes change and gap water in the grits underground are sampled periodically with main research object ground, and the action which HOCHYARE causes the water quality is clarified in respect of YUURAPPU river which is the representative salmon going againt stream river in southern part of Hokkaido. For willows and swamp ash and waterfront herbaceous plant which are a main tree species of the river levee, the stable isotope nitrogen analysis is carried out, and the actual condition of nutrient absorption of the HOCHYARE derivation is clarified.
