Abstract: The adaptation of urban water systems to climate change is a complex management challenge. Especially urban drainage systems and their adaptation to growing climate change dynamics, like increasing variations in terms of intensity and frequency of heavy rainfall events, calls for novel adaptation approaches. Growing data availability opens the chance to find suitable cost-effective solutions to tackle climate change risks. In the Damsgard area in Bergen, combined sewer overflows discharge in the fjord during extreme rainfall events. Within the European project BINGO, an evaluation of alternative ways to reduce this environmental pressure is being conducted, using extensive climate, economic and spatial data. The analysis is going to compare different combinations of green infrastructure from the field of water sensitive urban design, like green roofs, ditches and swales. These combinations are furthermore compared with an innovative approach: using the slope of roads as emergency flood water ways.
