GIS-Based Risk Assessment on Sea Level Rise and Flooding in Alsancak Harbour Behind Area

Abstract

According to climate change projections outlined in the Intergovernmental Panel on Climate Change 6th Assessment Report, sea levels are expected to rise between 0.37 and 1.88 meters by 2150. The rise in sea level poses a significant threat to coastal areas, including industrial heritage zones frequently developed around ports. Alsancak Harbour Behind Area is a significant location due to its essential industrial heritage. The main objective of the research is to evaluate the potential risks related to floods and long-term sea level rises in the Alsancak Harbour Behind Area. Thus, the research aims to assess the potential risks associated with flooding and long-term sea level rise in the Alsancak Harbour Behind Area within the context of industrial heritage. It also measures the area's resilience to these risks and discusses planning decisions. The ‘Coastal Risk Screening Tool’ was used to create a coastal flood map according to determined three different scenarios. The result shows that the valuable industrial heritage buildings such as the Coal Gas Factory, Old Flour Mill-II and Tariş Alcohol Factory, new high-rise residential areas, port facilities and transportation arteries are at high or medium risk, especially in 2100 and 2150.
