Water management in local development plans: the case of the old Fruit and Vegetable Market in Bologna

摘要

This paper describes the hydraulic simulation of an urban drainage system with SWMM 5.0 in order to evaluate the behavior of different solutions for the management of urban runoff. In particular have been analyzed different solutions for the flow peak reduction in the receiving water: retention basin, green roofs and infiltration tanks. The reuse of rainfall for irrigation has been analyzed in order to evaluate the reduction in the volume that flow into the sewer system. The simulations were performed adopting a long time rainfall series of 15 years recorded in Bologna (Italy).
