Projections of potential submerged area due to sea level rise are helpful for improving understanding of the influence of ongoing global warming on coastal areas. The Ensemble Empirical Mode Decomposition method is used to adaptively decompose the sea level time series in order to extract the secular trend component. Then the linear relationship between the global mean sea level （GMSL） change and the Zhujiang （Pearl） River Delta （PRD） sea level change is calculated： an increase of 1.0 m in the GMSL corresponds to a 1.3 m （uncertainty interval from 1.25 to 1.46 m） increase in the PRD. Based on this relationship and the GMSL rise projected by the Coupled Model Intercomparison Project Phase 5 under three greenhouse gas emission scenarios （representative concentration pathways, or RCPs, from low to high emission scenarios RCP2.6, RCP4.5, and RCP8.5）, the PRD sea level is calculated and projected for the period 2006-2100. By around the year 2050, the PRD sea level will rise 0.29 （0.21 to 0.40） m under RCP2.6, 0.31 （0.22 to 0.42） m under RCP4.5, and 0.34 （0.25 to 0.46） m under RCP8.5, respectively. By 2100, it will rise 0.59 （0.36 to 0.88） m, 0.71 （0.47 to 1.02） m, and 1.0 （0.68 to 1.41） m, respectively. In addition, considering the extreme value of relative sea level due to land subsidence （i.e., 0.20 m） and that obtained from intermonthly variability （i.e., 0.33 m）, the PRD sea level will rise 1.94 m by the year 2100 under the RCP8.5 scenario with the upper uncertainty level （i.e., 1.41 m）. Accordingly, the potential submerged area is 8.57x103 km2 for the PRD, about 1.3 times its present area.

In this study,a high-resolution storm surge floodplain numerical model was established based on the ADCIRC ocean numerical model,and was used to simulate the storm surge floodplain of typhoon 9608"HERB",and the simulation results of tide level and storm water increase are in good agreement with the observation *** this basis,the influences of runoff,typhoon path,and typhoon intensity on the floodplain submerged area and depth were *** on the measured runoff data,10 sets of sensitivity experiments with runoff sizes ranging from 0 to 2.5 times were set *** experimental results show that the increase of runoff mainly increases the submerged area of the coastal area in the upper reaches of the Minjiang River,but has a small effect on the submerged area of the coastal area in the lower reaches of the Minjiang River and the outer sea *** on the original typhoon path,8 different deflection paths after the typhoon landed were constructed to carry out sensitivity *** results show that the clockwise deflection of typhoon path of 10°-40°to the south will reduce the submerged area,and the counterclockwise deflection of 10°-30°to the north will increase the submerged area,but the counterclockwise deflection of more than 40°to the north will decrease the submerged *** weather systems before and after landing of typhoon center pressure of 955 HPA,935 HPA,and 915 HPA was *** results show that the decrease of typhoon center pressure will significantly increase the submerged area of the entire *** with the air pressure of 975 HPA,the submerged area is increased by about 2 times.
