Abstract
Recent reports by the Intergovernmental Panel on Climate Change and others have concluded that increasing atmospheric concentrations of carbon dioxide and other gases can be expected to cause a global warming that could raise sea level a few meters in the next century. Unfortunately, it is not yet possible to accurately predict future sea level. Estimates for the year 2050 range from five to thirty-two cm above current sea level, while estimates of the rise by 2100 range from nine to eighty-eight cm. Several issues must be resolved for society to rationally address the possibility of a significant rise in sea level. Officials in coastal areas making decisions about near-term projects with long lifetimes must determine whether the risk of sea level rise justifies a shift to strategies that can more successfully accommodate a rise in sea level. The research community needs to decide whether to accelerate studies to more accurately project future sea level. These decisions require assessments of the adequacy of existing forecasts, prospects for improving the estimates, and the level of resources that can be saved if more definitive estimates become available. These decisions also require a full understanding of the consequences of sea level rise.
Integration of many elements of geographic data is required when comprehensive assessment of impacts of sea level rise is carried out, using geographic information systems. Therefore, geographic data has to be prepared for evaluation if the region of research is in a critical condition. This study examines vulnerability assessment to the impacts of sea level rise in Marina El-Alamein tourist resort on the north western coast on the Mediterranean Sea using GIS techniques. Because current trends in sea level and other factors are already causing significant erosion at the resort and other beach resorts, and a small rise in sea level would erode most of the existing recreational beaches leaving seafront houses standing in the water, removing the primary reason people visit these communities in the first place. A high resolution elevation model of Marina resort was generated to estimate effected areas depending on different sea level rise scenarios. Classification map of the affected areas is produced to establish a priority list of actions. Strategies for addressing coastal problems constitute a class of near-term decisions and long-term decisions that may enhance the eventual success of erosion control at Marina resort and other coastal communities.
