Parameterisation and validation of the CleanCityCover tool to assess source areas of urban diffuse pollution for case study areas in Aarhus, Denmark 1: Technical University Berlin, Berlin, Germany; 2: Aarhus University, Aarhus, Denmark; 3: Kompetenzzentrum Wasser Berlin, Berlin, Germany Diffuse pollution from polluted urban surfaces and transported with stormwater runoff into surface waters remains a significant challenge towards achieving zero pollution from cities. Often it appears to be not clear where what kind of pollution actually originated. We therefore adopted a pollution source area approach to develop a tool named CleanCityCover, which identifies critical source areas of urban diffuse pollution. The tool was parameterised for four study areas in Aarhus for three pollution types – dry deposition, pollution due to traffic and metal roofs. The CleanCityCover is a web-based, interactive tool displaying the spatial patterns of different pollution types, summary of annual runoff quality, results of functional connectivity analysis and a pollutant ranking summary. The tool is validated for heavy metal (zinc, copper and lead) concentrations from the runoff of three of the four study areas in Aarhus. A reasonable validation was achieved at the three study areas with correlation coefficient varying from 0.57 to 0.92. | |
