Comparison of pollutant runoff in Lake Biwa tributaries, Japan and the Brunette River watershed, Canada

This study is aimed at verifying runoff pollutant loadings from urban areas , Urban runoff has been considered an important source of diffuse pollution especially during storm events. This paper describes the pollutant runoff during storm events, mainly in terms of effects of watershed characteristic s. Data collected from Lake Biwa tributaries, Japan, have shown fundamental information to control pollutant runoff into receiving water. Also, data f rom the Brunette River watershed, Canada, which is a highly urbanized water shed in the Vancouver region, have been used for a comparative analysis. In the results, available information for the environmental management of urb an storm water runoff was obtained by comparing the data on pollutant runof f in both watersheds.
