Water quality and natural environments of the enclosed sea such as Osaka Bay in Japan, has been chronically worse by the high pollution load owing to human activities in the city. It is important for the environments to develop a management system. In order to understand the environments deeply and to propose the suitable managing system, not only measurements in detail but also numerical simulation should be made. In the present paper, the numerical simulation method of water qualities is constructed using the ecosystem model with land water effects in Yura area, where is located in the southern part of Awaji Island. This method is useful to predict the environments because these can be treated physical, chemical and biological processes. The load from land is calculated using the prediction method of run-off polluted load through river basins. The results of numerical simulation show that the load from town area is very large, but does not affect so strong to nutritive salts and phytoplankton in the coastal areas.
