The urban hydrology research group is part of the HYDR department. Within the department there is a strong emphasis and experties in quantitative assessment of hydrological fluxes in urban environments. They aim at improving integrated rainwater management (IRWM), hence increasing resilience to climate change impacts such as floods and droughts. Hence, they rely on nature-based solutions and citizen science. A great part of the research projects of the urban hydrology research group is done in the Brussels Capital Region, an urban region in full transition, in which they have an extensive network among institutions, civil associations and private actors via past and ongoing projects such as Brusseau(Bis) and FloodCitiSense.
