  • Abstract en This paper addresses estimation of water quality loads, resulting from not only usual inflow but flood due to snowmelt and rainfall, flowing out from a watershed in snowy cold region. We also investigated a method for estimating water quality loads from runoff components, which consist of surface, interflow and groundwater runoff. Relationships between water quality loads and geographic condition, such as soil and land use, were also analyzed to clarify the causes of supplying water quality loads. As a result, it was found that the effect of water quality loads during flooding could not be ignored the proportion of water quality loads in the floods to the total loads was large. Relationship between non-point source loads related to eutrophication and geographical condition in watershed was also clarified.
