Abstract

This paper describes the modelling efforts of compartmentalized stormwater detention system. Such a system consists of multiple modular units that creates compartments to hold stormwater. Particular attention is paid to a specific R&D product named StormPav Green Pavement System. US EPA’s SWMM5 is utilized as the tool to explore two of its functions, namely the storage unit and conduit to model flow through a StormPav system. The first model assumes the compartmentalized characteristics of StormPav could be represented by applying the effective storage volume in a storage unit; while the second model, using a conduit. A StormPav field test is constructed, and the data collected are used to validate the two models. The outcomes show that model with storage unit is better representing the compartmentalized stormwater detention system.
