| Outline of Final Research Achievements |
Flow fluctuations in rivers have dominant influence on physical habitats, primary production, water quality, and the like. In this study, based on the distributed hydrological model, we elucidated and modeled the response of river ecology (river channel topography, riverbed adhesion membrane, fish) to riverbed disturbance caused by flow variation on the basin scale. The analysis of the Sagami River basin has revealed that the seasonal fluctuation pattern of the flow rate shows a close relationship with fish distribution and that model accuracy is improved by integrating the preceding environmental conditions. We also developed a method of evaluating the response of the topography of the river channel using satellite image and a model of the response of the riverbed periphyton to the water discharge disturbance.
