In this study three conceptual models simulating the daily scale green roof (GR) runoff production have been proposed. The three approaches have an increasing complexity, and they are compared, against experimental data, with the aim to assess if their performances improve consequently to their complexity. Model increasing complexity is achieved moving from an approach based on the use of potential evapotranspiration and a constant storage threshold to an approach where actual evapotranspiration and a variable storage threshold are accounted for. The main findings confirm that, if interested at the daily scale simulation, the larger model complexity the better the performances, but, if interested in the computation of long term runoff, a basic approach, using a minimal set of climate data, is indeed sufficient

Abstract
In this study three conceptual models simulating the daily scale green roof (GR) runoff production have been proposed. The three approaches have an increasing complexity, and they are compared, against experimental data, with the aim to assess if their performances improve consequently to their complexity. Model increasing complexity is achieved moving from an approach based on the use of potential evapotranspiration and a constant storage threshold to an approach where actual evapotranspiration and a variable storage threshold are accounted for. The main findings confirm that, if interested at the daily scale simulation, the larger model complexity the better the performances, but, if interested in the computation of long term runoff, a basic approach, using a minimal set of climate data, is indeed sufficientI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
