  • Abstract en This paper discusses the characteristics of loads of water quality components in a basin in a cold, snowy region. The total load of water quality components was estimated for the Ishikari River basin, which includes forests, farmland and urban land. The load from non-point sources was estimated by subtracting the load from point sources, which was estimated on the basis of population and industrial activities, from the total estimated loads of the basin. Because the ratio of non-point source origin load to total load is high, it is useful to evaluate the water quality based on the use. The contribution ratio of the water quality component load from each source (i.e., each land use) was estimated for the entire basin.
