Impact of sea level rise in the Gulf of Sidra, Libya Using SRTM-DTM

Abstract

Emission of greenhouse gases, increased use of CFC etc are responsible of global warming, which leads to the sea level rise (SLR). According to (Nicholls and Hoozemans, 1995) allowing population growth further increases the vulnerability analysis indicates at least 400 million people would live beneath the 1 in 1000 years storm surge after a Im rise in SLR in the Mediterranean region. The study area lies in the north east Libya fronting the Gulf of Sidra and boarders with the Mediterranean Sea in the north. The study area is used for settlements, oil refinery, harbour and seasonal agriculture. It has a coastline of265 km and a population of 190397 (report 2005). The study area lying between 130 m above sea level and 37m below sea level. In methodology M, SRTM-DTM, has been used to analysis the impact of SLR and coastal change. Analysing SRTM-DTM model gives us a better picture of 1 % & 2 % increase of impact of SL in future due to higher resolution and accuracy of the image. Vulnerability in economic sectors like the urban area and road, there is an increase of the impact in percentage more than those of the pipelines (drinking water and oil pipelines).
