Abstract
Urban infrastructure such as water and sewage handling is considered to be particularly at risk following climate change. Identifying vulnerable parts of the system may prove useful in order to secure and provide adequate and sustainable water and sewage handling in a long term perspective. This thesis aims to further develop the indicator and GIS-based methodology for mapping physical vulnerability proposed and developed by Karlson (2010). Following an extensive literature study several vulnerability indices where developed for three urban systems in connection to specific climate related threats. The studied systems include the pipe network (water, sewage and storm water), the municipal groundwater supply and the urban development. The... (More)
Urban infrastructure such as water and sewage handling is considered to be particularly at risk following climate change. Identifying vulnerable parts of the system may prove useful in order to secure and provide adequate and sustainable water and sewage handling in a long term perspective. This thesis aims to further develop the indicator and GIS-based methodology for mapping physical vulnerability proposed and developed by Karlson (2010). Following an extensive literature study several vulnerability indices where developed for three urban systems in connection to specific climate related threats. The studied systems include the pipe network (water, sewage and storm water), the municipal groundwater supply and the urban development. The hazard studied in connection to the pipe network was its vulnerability to breaking, due to the increased risk of landslides. For the groundwater supply three hazards connected to the increased risk of pollution were studied; MIFO-objects, farmland and individual home sewage treatment. One of the studied hazards as regards the urban development was the risk of flooding due to either under dimensioned storm water piping or surface runoff into local topographic sinks. The second hazard studied in connection to the urban development was the risk of landslide. The methodology was applied to the municipality of Bromölla. The resulting maps where used to identify vulnerable areas or parts of the respective systems. An analysis of the insecurities of the method was also performed. In conclusion, the indicator methodology appears well suited for visualizing and mapping the physical vulnerability on a municipal level. (Less)
