The present paper deals about the relation between the disturbance (river construction and floods) and river ecology system. It is very difficult that disturbance is divided into fixed quantity. Therefore, study on the restoration of benthic animals communities is not many. In this paper, the results of observations on the restoration of benthic animals communities after construction river works and floods intended for the HIRAI and AKI river are reported. We was considering to contents of disturbance by spectral analysis. As an estimation, It was found that change of benthic at the AKI river have occurred periodically at certain interval, but benthic of the HIRAI river have irregular periods.
