We are now developing a comprehensive global environmental model, and this is one of the submodules focused on material transport via surface water runoff and ocean circulation. The model is composed with basinscale watershed runoff part and global scale ocean circulation part. Both are supported by a global scale geographical information system and organically connected with other modules. Though the submodules written here are in preliminary stage and expected to be refined by fine tuning effort, global environmental crisis of these day requires strongly such a detailed but comprehensive approach.
