Abstract

The numerical simulation was carried out for the analysis of water quality, sediment quality and release rate of nutrient from sediment at Tokyo port which is located at bay head area of Tokyo bay by the water and sediment quality model. As the results of the simulation, it was confirmed of their characteristics of seasonal and spatial variation. Next, the effect of pollutant load reduction on water quality and release rate of nutrient from sediment was analysed. As the results of the analyses, it was confirmed that the reduction rate of water quality and release rate of nutrient from sediment were smaller than that of pollutant load and the response of water quality and release rate of nutrient from sediment was linear for the pollutant load reduction.
