A Meta-Analysis Of Experiments On Hydraulic Properties Of Porous Pavements

A meta-analysis of studies evaluating the effect of porous pavements on surface hydrology. The analysis investigated experiments on infiltration rate and consequent runoff coefficient of porous pavements. Reviewed literature provided extensive indications on the benefits of porous pavements in mitigating hydrology in the built environment. It was demonstrated that previous pavements improved the hydrological properties of engineered surfaces including mitigating runoff and checking to flood. Accordingly, it was hypothesised that the mean effect among the selected studies is zero. A meta-analysis of selected experiments on porous pavements experiments established that the mean effect among the selected studies was zero. While the study adopted a methodology that included similar studies in terms of method, further study is recommended to control for the various factors that influence hydraulic properties of porous pavers mentioned in the conclusion of this study.
