Outline of Final Research Achievements

In order to reveal contamination of lead derived from a battery factory in the river and coastal area in Dominican Republic, many sediment and massive coral samples were collected from the river mouth of Rio Haina and analyzed for lead. In addition, diffusion of suspended matters from the river mouth of Rio Haina were predicted using the satellite observation data, while a quantitative model was proposed using the satellite observation data for estimation of suspended matters distribution. Applying the ALOS AVNIR-2 data to these models, mapping of suspended matters was carried out. Finally, a coastal environment simulation was carried out to predict 3-dimensional diffusion of suspended matters from the river mouth of Rio Haina to the Caribbean Sea.
