“…That behavior is in agreement with results reported in the literature. Illgen et al (2007), in his laboratory campaign, confirmed that the wear layer has the major influence on the infiltration capacity of the permeable pavement, while the base and sub-base layers have a minor impact and act as a storage tank. The total index is always greater than zero, which implies that all parameters influence the output variance either directly or by their interactions, and thus no parameter can be fixed without affecting the uncertainty of the output.…”

“…HYDRUS has also been used for the description of variably-saturated flow in permeable pavements. Illgen et al (2007) used HYDRUS-2D for the numerical analysis of a permeable pavement and calibrated the model against experimental data collected at a laboratory test facility. The calibrated model was then used to simulate different scenarios not investigated during the laboratory campaign.…”

“…The calibrated model was then used to simulate different scenarios not investigated during the laboratory campaign. The Illgen et al (2007) study provided only limited details about the calibration of soil hydraulic parameters and their uncertainty and sensitivity. The occurrence of preferential flow in the permeable pavement was also not investigated.…”

a b s t r a c tThe increasing frequency of flooding events in urban catchments related to an increase in impervious surfaces highlights the inadequacy of traditional urban drainage systems. Low Impact Development (LID) techniques have proven to be a viable and effective alternative by reducing stormwater runoff and increasing the infiltration and evapotranspiration capacity of urban areas. However, the lack of adequate modeling tools represents a barrier in designing and constructing such systems. This paper investigates the suitability of a mechanistic model, HYDRUS-1D, to correctly describe the hydraulic behavior of permeable pavement installed at the University of Calabria. Two different scenarios of describing the hydraulic behavior of the permeable pavement system were analyzed: the first one uses a singleporosity model for all layers of the permeable pavement; the second one uses a dual-porosity model for the base and sub-base layers. Measured and modeled month-long hydrographs were compared using the Nash-Sutcliffe efficiency (NSE) index. A Global Sensitivity Analysis (GSA) followed by a Monte Carlo filtering highlighted the influence of the wear layer on the hydraulic behavior of the pavement and identified the ranges of parameters generating behavioral solutions. Reduced ranges were then used in the calibration procedure conducted with the metaheuristic Particle swarm optimization (PSO) algorithm for the estimation of hydraulic parameters. The best fit value for the first scenario was NSE = 0.43; for the second scenario, it was NSE = 0.81, indicating that the dual-porosity approach is more appropriate for describing the variably-saturated flow in the base and sub-base layers. Estimated parameters were validated using an independent, month-long set of measurements, resulting in NSE values of 0.43 and 0.86 for the first and second scenarios, respectively. The improvement in correspondence between measured and modeled hydrographs confirmed the reliability of the combination of GSA and PSO in dealing with highly dimensional optimization problems. Obtained results have demonstrated that PSO, due to its easiness of implementation and effectiveness, can represent a new and viable alternative to traditional optimization algorithms for the inverse estimation of unsaturated hydraulic properties. Finally, the results confirmed the suitability and the accuracy of HYDRUS-1D in correctly describing the hydraulic behavior of permeable pavements.

“…Clogging, the loss of surface permeability, in PP systems has been documented by numerous researchers in both field (Bean et al, 2007;Henderson and Tighe, 2011) and laboratory based studies (Illgen et al, 2007;Pezzaniti et al, 2009;Haselbach, 2010;Tan et al, 2003). Clogging materials are deposited onto the surface of a PP from vehicular traffic, vegetative litter, atmospheric deposition and regular maintenance activities.…”

Permeable pavements (PPs) have been used as stormwater management systems throughout Ontario for over twenty years. After years of sediment and debris buildup, surface clogging reduces the infiltration of stormwater and inhibits the hydraulic and environmental functions of the pavement. Removal of surface material has been shown to restore infiltration but the majority of studies have been limited to small scale testing.This chapter presents the results and experiences of the first testing of regenerative air and vacuum sweeping trucks on permeable pavements in Ontario, which was conducted in 2011. A regenerative air truck was tested on two parking lots with well used permeable interlocking concrete pavers and pervious concrete, while a vacuum sweeping truck was demonstrated on a third parking lot with permeable interlocking pavers.Both systems proved to provide partial rehabilitation of the permeable pavements. Post treatment surface infiltration rates on all three parking lots displayed large spatial variability, showing that micro-conditions throughout the pavement have a confounding influence on the overall effectiveness of maintenance. The impact of maintenance may be improved by establishing regular cleaning intervals and developing instructional guidelines for pavement owners and equipment operators.

This paper presents a technological review of permeable pavement systems (PPS) for applications in urban areas of small island developing states (SIDS). This review includes a literature survey of PPS, challenges and opportunities of climate change and urban development in SIDS and key aspects worth considering for widespread acceptance and use of PPS in SIDS. SIDS comprise of several nations located across the Atlantic, Pacific and Indian Oceans and the Caribbean, Mediterranean and South China seas. They are particularly susceptible to the effects of climate change and increasing urbanisation. Urban stormwater management and flooding are often serious challenges faced by authorities in most SIDS. PPS are resilient infrastructure which can assist in mitigating flooding by reducing runoff and peak flows and improving the landscape perviousness. PPS can further improve stormwater runoff quality to receiving natural waters by reducing pollutant loadings of suspended solids, heavy metals and hydrocarbons. Unlike most territorial states, the geographical and geologically confined nature of most SIDS present unique parameters for consideration when designing permeable pavements for SIDS. This literature survey found that some of the most important parameters include traffic loads, cost, construction aggregate choice and availability, permeability of existing soil at the intended location, depth of water table, potential for groundwater contamination, slope of the pavement, stormwater reuse option, clogging, maintenance and support from policy makers. Continued practical research into the use of permeable pavements for urban runoff management in SIDS is ongoing with the expectation of PPS being utilised in many SIDS.
