Abstract:To prevent and mitigate the damage of inundation resulted from the sea-level rise around Bohai Bay of Shandong province in the future, global sea-level rise data, land subsidence data and the tide data of Dongfeng port were used to forecast the 100-year-recurrence-period storm surge tide line data in 2100. The impact of sea-level rise on the tide line was evaluated using Digital Elevation Model and Geographic Information System. According to the analysis, we got the following results: (1) the data of the tide level location in 2100; (2) the spacial distribution of the new inundated land caused by 100-year-recurrence-period tide level in 2100 compared with that of 2000; (3) the area of the new inundated land and the shoreward moving distance of coastline caused by 100-year-recurrence-period storm surge in 2100 compared with that of 2000. The data indicated these following conclusions: (1) the inundated area will be increased along with the sea-level rise in 2100; (2) compared with 2000, the new inundated area will mainly locate in the central and western region; (3)industry, agriculture, graziery, fishery and even the population of these new inundated areas would be heavily affected.
