Hydrologic Design of Green Roofs

Abstract :-
Green roofs are increasingly being used as part of primary urban strategies to improve storm water management and reduce energy costs. Different methods for green roof design are based on different assumptions and parameters. However, the input parameters are uncertain, which influences design accuracy. A mathematical model was developed to simulate the water movement across and through a green roof. This model was used to assess the sensitivity of the hydrological response of a green roof to roof and rainfall characteristics. Peak discharge rates and depths of runoff mainly depend on the rainfall characteristics. Continue reading Hydrologic Design of Green Roofs
