| Summary | We have analyzed the characteristics of the relationship between water quality and river basin environment for the five river basins. Paddy fields, farmland, livestock, industry shipments, and population of unused sewer relate to water quality in fine weather. As these data value increases, water quality tends to deteriorate. Creating a relationship of water quality and river basin environmental data, it is possible to estimate the average river water quality. |
