Especially, the environmental impact has been concentrated to the Barato River with stagnated waters which is in the end of this circulatory system. This paper deals with the improvement of water environment of waters flowing from urban area from the view point of hydrologic cycle restoration. It was clarified that the transition of the load by the city drain has exerted influence on the water quality in the Barato River. Then the ecosystem model was developed to evaluate the influence of water circulatory in urban area on water environment of the Barato River. As a result, it was verified that the amount of the water circulation is effective in the environmental improvement of the Barato River. Based on the analysis, introducing water to the stagnant water area was proposed as an effective measure for improving water quality.}, pages = {1111--1116}, title = {都市流末水域の水環境に着目した水循環再生の評価}, volume = {53}, year = {2009}, yomi = {スギハラ, コウキ and ナカツガワ, マコト and セイジ, マサト} }
