As the main water transport passage of the South-to-North Water DiversionProject, the Grand Canal (North Section of Jiang Su) would directly influence theeffects of the quality of water transport. After the water transport, the environmentalconditions and water power conditions would change and break the equivalent state ofpollutants of sediments and previous aqueous phase, especially the persistentorganisms would re-enter the previous aqueous phase and thus influence the waterquality of water transport.
