Abstract：by analyzing the topography and hydrological data in Shanghai, it is found that Shanghai is not a water-stress city, there are a giant freshwater mine with good quality in Shanghai, which locates at Chongtou of Chongmin Island. Based on this discovery, it is proposed that coastal reservoirs shoud be built on the north and eastern sides of Chongmin island to store the freshwater, therefore the water shortage problem can be completely solved. It is also suggested that the soft barrier invented by the author be able to solve the problems in artificial gold beach project proposed by Shanghai government, thus the waves and tides could appear in the beach; it is also found that the coastal reservoirs can reuse the ballast water by ships, thus the marine environmental could be effectively protected from the invasive ballast water; it is also concluded that the coastal reservoirs in Yangshan port can economically replace the desalination plant.
