A critical aspect of water quality modeling, particularly for long term predictions and considering measures against hypoxia and anoxia, is the long-term estimation of sediment quality. The objective of this study is to reproduce spatial distribution of sediment quality in Tokyo Bay, particularly particulate organic carbon content (POCC) of sediment, by adopting integrated, benthic-pelagic coupled, layer-resolved, and process based ecosystem model. This model could reproduce spatial distributions of sediment quality, including water content (WC), POCC, total nitrogen content (TNC) and total phosphorous content (TPC), showing the largest contents at the central part of the inner bay. Robustness of the model for long term formation of sediment quality has been proved through this study.
