Abstract

The deposition and transport of sediments should be managed properly in ports not only for the maintenance of port channels, but also from an environment perspective. Our focus in this study was to create maps of sediment spatial distributions in Tokyo Bay by using chemical composition. We collected sediments from 449 stations in the bay and analyzed particle-size distribution and chemical composition. Sediments were grouped by chemical compositions using k-means clustering and maps of the spatial distribution of sediments were drawn up. These maps enable determination of spatial distributions of sediments from each main river that enters the bay.
