Abstract: According to a very recent report of the European Environment Agency (EEA, 2020), urban adaptation to climate change requires special attention to extreme weather events and particularly heavy storms, as they are expected to cause the most pronounced impacts in European cities. In agreement with this direction, some Italian regions are setting regulations to limit surface runoff production in urban areas. Most of them include measures to ensure compliance with the principle of the ‘hydraulic’ and ‘hydrological’ invariance for the urban area, meaning that runoff volumes generated by an intense meteoric event must remain unchanged or at least must be limited. In some cases, municipalities are even requested to prepare the Hydraulic Risk Management Plan, as a response to the need of a more effective stormwater management. The planning activity requires a modelling framework accounting for both the open channel network (mainly addressing irrigation demand) and the sewer pipe network. Preliminary results are presented here for Brescia, a town located in Northern Italy, at the foothills of the Alps. Potential flood risk is linked to the dense historical irrigation and drainage channels network that cross the urban area from north to south and the old city centre.
