Multihydro

Influence of precipitation spatial distribution on these performances

Based on radar rainfall fields (characterized by a resolution of 1 km in space and 5 minutes in time), an ensemble of 50 realistic downscaled rainfall fields with a resolution of 12.3 m in space (and converted to 10 m) has been generated. The rainfall input downscaling technique relies on the framework of Universal Multifractals (Schertzer and Lovejoy, 1987), which has been extensively used (Schertzer and Lovejoy, 2011 for a recent review) to analyse and simulate geophysical fields extremely variable over wide ranges of scales.

For each downscaled field, responses to current (impervious) and green roofing configurations have been analyzed and compared
