Abstract: The dynamic state of sea level rise in the Changjiang Estuary and its impacts on tidal characteristics were summarized and analyzed. Then three series of 1-D river-net tidal hydraulic model based on sea level rising in the Changjiang Estuary, respectively for Chongming island, Changxing island and Hengsha island in Chongming county, were established. Thereafter impacts of waterlogging-controlling safety on Chongming county under sea level rise were studied respectively and deeply. Up to the year of 2030, when the sea level may rise up by 10-16 cm in the Changjiang Estuary, both of the mean regional waterlogging-controlling highest water level and the mean local highest water level within Chongming county will present uprising situation. The impact on Chongming island is the most, the two above mentioned water levels will rise up by 3-5 cm and 4-6 cm respectively; for Changxing island, its impact is minor, the water levels will rise up by 3-4 cm and 3-5 cm respectively; for Hengsha island, its impaction is the least, both water level will rise up by 1-2 cm and 1-2 cm respectively; but all impacts due to sea level rise on Chongming county?waterlogging-controlling safety will be under control.
Key words: Chongming county, sea level rise, waterlogging-controlling safety, 1-D river-net hydraulic model
