Permeable pavements are a solution to many of the problems Water Sensitive Urban Design seeks to combat as they reduce peak flows and filter pollutants. These installations do however slowly clog over time due to sediment build up in the paving joints and this clogging reduces their effectiveness. This research project examines the infiltration rates of several permeable pavements installations across the Sunshine Coast and compares this to the particle size distributions of sediments extracted from those sites. The relationship between infiltration rate and PSD is examined and this research project demonstrates that there is a correlation between the presence of sediments of moderate to fine size and low infiltration rates. In addition the link between the presence of fine and moderate sized sediments is examined and there is shown to be a positive correlation between the two.
