Forecasting green roof detention performance by temporal downscaling of precipitation time-series projections

Abstract. A strategy to evaluate the suitability of different multiplicative random cascades produce rainfall time series, taking into account climate change, inputs for green infrastructures models. The reproduce a (multi)fractal distribution precipitation through an iterative and process. In current study, initial model, flexible cascade that deviates from multifractal scale invariance, was improved with (i) temperature dependency (ii) additional function temporal structure rainfall. models depth found be applicable in eight locations studied across Norway France. resulting series both reference period projection based on RCP 8.5 were applied two roofs properties. led slight change performance roofs, but this not significant compared range outcomes due ensemble uncertainty modelling stochastic nature hydrological dampening effect infrastructure decrease most Norwegian cities increase precipitation, especially Bergen (Norway), while slightly increasing Marseille (France) event frequency.
