【摘要】：为评估海平面上升对上海市大陆片区防洪除涝造成的影响,构建了上海市大陆片联片联动一维河网水动力模型,模拟分析了上海市海平面上升前、海平面上升10、16cm三种情况下的各水利分区除涝面平均最高水位、防洪除涝局部最高水位、除涝最高水位等。结果发现,随着海平面上升,卲南片、浦东片、浦南东片、浦南西片和太南片面平均最高水位明显呈上升趋势,当海平面上升10、16cm时,卲南片面平均除涝最高水位上升近5.9、9.3cm;对卲南片、浦东片、浦南东片、浦南西片和太南片五个水利片局部最高水位的影响较大,各局部水位最高点水位变幅为4~10cm;对黄浦江防汛高水位的影响也十分明显,当海平面上升10、16cm时,黄浦江除涝最高水位将增高7.7、12.3cm。
[Abstract]:In order to evaluate the effect of sea-level rise on flood control and waterlogging in Shanghai's continental area, a one-dimensional hydrodynamic model of Shanghai continent-plate linkage was constructed and analyzed before sea level rise in Shanghai. Under three conditions of 10 ~ 16cm sea level rise, the average maximum water level in the dewaterlogging surface, the local maximum water level in flood control and waterlogging removal, the maximum water level in flood control and waterlogging, and so on. The results show that, with the sea level rising, it is found that, with the rise of sea level, the South, Pudong, Punan, East, etc. The maximum water level of the west and Tainan one-sided mean water levels is obviously rising. When the sea level rises by 10 ~ 16cm, the maximum water level increases by 5.9 ~ 9.3cm. The influence of the local maximum water level of the five water conservancy plates in Punan West and Tainan is great, the maximum water level of each local water level is 410cm, and the influence on the flood control high water level of Huangpu River is also very obvious. When the sea level rises 10 ~ 16cm, The highest water level in the Huangpu River will increase by 7.7g / 12.3 cm.
