Abstract
Permeable car parks, as part of SuDS (Sustainable Drainage Systems), are developed for better management practice of urban stormwater. Even if lots of researches studied permeable pavements, none specifically studied green permeable pavement impact on urban water quantity and quality, or modelled its behaviour. In this study three types of experimental parking places (1 with gravels and 2 with vegetation) are monitored. The data obtained from a simulated rain event and a natural rain event, served to test and adapt a reservoir model, initially developed for green roofs. First calibration tests showed that permeable car parks (vegetalized or not) behaviour can be simulated with the reservoir model with a calculated water mass balance around ±15% for different conditions. However, the model needs to be improved to have better water mass balance results, and to be better adapted to green permeable car park.
