Approaches for green roof dynamic model analysis using GSA

Résumé

Green roofs are a sustainable solution to manage water runoff from rain events in urban areas. Modeling hydrological phenomenon of green roofs is challenging because of the difficulties to characterize the soil parameters, inducing uncertainties on these parameters. Soil parameter uncertainties spread in the model and need to be analysed to better understand the dynamics of the water retention. For this purpose, the water retention capacity is represented by the Van Genuchten-Mualem model and sensitivity analysis is performed. Different methods of sensitivity analysis are considered to quantify effects of parameter uncertainties on the water retention capacity. The results of this study highlight the most influential soil parameters of the substrate on the water retention capacity.
