abstract
Substance load from land to the ocean has been clarified. In this research, it aims at evaluating the changes in the amount of loads of a basin based on statistical information and geographical information; such as land use and population information using the original unit method. Two rivers located in Hiroshima Prefecture which flow into the Seto inland sea are mentioned as examples. This research showed that the amount of nutrient outfl ows in the Ota River watershed and the Ashida River watershed was increasing. Although there was little growth of the nonpoint source load in the Ota River watershed and the Ashida River watershed, a large increase in the amount of discharge by the domestic waste water were seen
