Longitudinal distribution of sediment composition in the Kita River

Abstract

In the recent years, river restoration has been carried out in Japan. In those cases, we need some information of sediment movement and geology of river basin relationships because of river management of the basin scale. However, the information of these relationships is still poorly understood. The Kita River runs through the northern part of Miyazaki prefecture, and this river is one of the special research sites of river ecology in Japan. In this research, we investigated the deposited sediment component and geological map in the Kita River basin relationships.
