Permeable Pavements for Flood Control in Australia: Spatial Analysis of Pavement Design Considering Rainfall and Soil Data


This paper published by University of South Australia studies the design of permeable pavements,  which allows rainfall and surface runoff to infiltrate through their surface thereby reducing urban flooding.

A detailed hydraulic analysis was conducted considering the pavement materials, soil characteristics and rainfall intensities across Australia.  The results showed a strong relationship between soil characteristics and pavement thickness, with clay soils requiring increased pavement thickness correlated with rainfall intensity.
