Research Abstract |
To obtain a closer estimate of a amount of inflow loads, field surveys including rainy day surveys were carried out in rivers and sewerage treatment plants. The inflow load from the Neya River sub-basin showed largest amount, about 40% of total inflow load to Osaka Bay. Inflow loads due to floods and CSOs have a significant impact on nutrient cycle in the bay. Numerical results showed that future improvement of treated water quality was not effective in the reduction of organic pollution.
