In order to prevent the above tendency and to attain the sound and sustainable water environment, integrated management of river and watershed becomes more and more important. In this paper, mechanism of runoff from the pollutant source, especially the non-point pollutant one, is studied for estimating the causes of degradation in the closed water bodies. Through this study, it becomes apparent that organic nitrogen drastically runoff under the wet condition, even though inorganic nitrogen exceeds the organic one in the total amounts., 長崎大学工学部研究報告 Vol.29(53) p.321-328, 1999}, pages = {321--328}, title = {雨天時における流域からの窒素系汚濁負荷流出量の評価に関する研究}, volume = {29}, year = {1999} }
