Abstract
Rapid disposal of surface runoff to urban drains in conventional road drainage system makes it an ineffective measure to mitigate flood. Hence, On-Site stormwater Detention (OSD) is one of the common approaches to reduce the runoff volume in the dense developed areas. Normally, typical underground OSD facilities consist of tanks and pipe packages which increase the cost and complexity in construction. In this study, StormPav Green Pavement system is introduced as an alternative construction method to create the stormwater detention chamber. Dimension of a typical road shoulder in a housing estate is utilized as single unit of the stormwater detention system. Computational Fluid Dynamics (CFD) is applied on StormPav Green Pavement System as combined road shoulder and stormwater detention structure by utilizing SolidWorks Flow Simulation. Applicability of the system is tested by simulating flow through the multiple chambers within StormPav system via road curb-opening inlet and outlet. The CFD simulations demonstrate flow patterns resulted from 5-minute, 10-min and 15-min 10-year ARI design rainfall subjected to three design models with different locations of outlet (centerline, edge, between centerline and edge). The distance of inlet and outlet is found to play a major role in the flow pattern in the StormPav system. It is found that outlet located at edge is the ideal design for such a system. It has the most distributed flow and variations of velocity in the closed system. The further the outlet away from the inlet, the more the CFD simulations show flow trajectory plots that suggest a water mixing quality. This finding is interestingly point to a self-cleansing ability in the StormPav system that suggests the flow pattern is favorable to flush out sediments carried by stormwater from roads.
