Pluvial översvämning, kartering av riskområden : Kullö, Rindö och Resarö i Vaxholms stad / Pluvial flooding, mapping areas of risk : Kullö, Rindö and Resarö in Vaxholms stad

Short and intense rainfall, called cloudbursts, is becoming more frequent in Sweden as an effect of climate change. With that comes an increased frequency of flooding events caused by the heavy rainfall, called pluvial flooding. This is especially problematic in urban areas where large areas of impervious surface greatly increases the volumes of surface runoff. Mapping of bluespots, locations where pluvial flooding is more likely to occur, can be an important aid towards preventing this kind of flooding. This study concerns performing such a mapping for the islands Kullö, Resarö and Rindö in the municipality Vaxholms stad, Sweden. These islands are chosen for being future high development areas. The analysis is done through hydrological modelling of a digital elevation model. From that expected runoff volumes is calculated from statistical models of precipitation data. Analysis of the result concludes that the major road, 274, is expected to be affected by flooding along two sections. Some houses and other minor roads are also affected. But the overall impact on infrastructure and social functions is low. The mapping should be able to function as a tool in the flood preventative work of Vaxholms stad and in planning of future developments.
