“…The latter agrees with similar studies that found the suction head parameter to be insensitive in SWMM-LID modules (Krebs et al 2016;Randall et al 2020). The most sensitive parameters were found to be the hydraulic conductivity slope, the field capacity and the porosity of the soil layer.…”

“…The SWMM-LID module, hereafter referred to as the SWMM-PP model, is a simplified physically based model. It has been applied in many PP studies (Kim et al 2015;Chui et al 2016;Xie et al 2017;Randall et al 2020). Most of the studies applied the SWMM-PP model of PP using parameters selected from the SWMM manual without calibration, and only a few studies were found to evaluate the accuracy of SWMM-PP models with measured data.…”

“…Most of the studies applied the SWMM-PP model of PP using parameters selected from the SWMM manual without calibration, and only a few studies were found to evaluate the accuracy of SWMM-PP models with measured data. Randall et al (2020) investigated the accuracy of the SWMM-PP model using 18 rainfall-runoff events. They found the SWMM-PP model to yield simulation with reasonable accuracy for single-peak events and to perform poorly for events with multiple peaks.…”

“…Such an analysis is made before calibration to select the most influential parameters for calibration/measurement while assigning standard values of the insensitive ones. However, only one study was found to investigate the sensitivity of the SWMM-PP model for long-term simulation (Randall et al 2020). Hence, there is a need to investigate the sensitivity of SWMM-PP parameters for event-based simulations.…”

Hydrological performance of lined permeable pavements in Norway

Lined permeable pavements (LPPs) are types of sustainable urban stormwater systems (SUDs) that are suitable for locations with low infiltration capacity or shallow groundwater levels. This study evaluated the hydrological performance of an LPP system in Norway using common detention indicators and flow duration curves (FDCs). Two hydrological models, the Storm Water Management Model (SWMM)-LID module and a reservoir model, were applied to simulate continuous outflows from the LPP system to plot the FDCs. The sensitivity of the parameters of the SWMM-LID module was assessed using the generalized likelihood uncertainty estimation methodology. The LPP system was found to detain the flow effectively based on the median values of the detention indicators (peak reduction = 89%, peak delay = 40 min, centroid delay = 45 min, T50-delay = 86 min). However, these indicators are found to be sensitive to the amount of precipitation and initial conditions. The reservoir model developed in this study was found to yield more accurate simulations (higher NSE) than the SWMM-LID module, and it can be considered a suitable design tool for LPP systems. The FDC offers an informative method to demonstrate the hydrological performance of LPP systems for stormwater engineers and decision-makers.

“…In particular, sanding during winter maintenance should be avoided. The long-term infiltration performance is single-handedly the largest drawback of PA as it tends to become clogged by sand and fine material over time, which lowers the infiltration capacity and, thereby, the performance [18][19][20]. Støvring et al [20] evaluated the restoration cleaning effect on nine PP systems in Denmark.…”

This paper presents a multifunctional full-scale demonstration road, the Climate Road, which combines climate adaptation and mitigation in a single system. The Climate Road is located at Hedensted, Denmark and is 50 m long and 8 m wide, and the depth of the roadbed is 1 m. Half of the Climate Road, i.e., 25 m, is paved with permeable asphalt and the remaining 25 m with traditional asphalt. All surface water drains into the roadbed, which stores up to 120 m3 of water, either directly through the permeable asphalt or by drain grates. In addition, 800 m of geothermal pipes are embedded in the roadbed, distributed over four 200 m w-loops, two buried 1 m below the asphalt and two similar loops at 0.5 m depth. The Climate Road was tested from May 2019 to May 2021. In the project period, a total precipitation value of 1654 mm was recorded, the mean temperature was 9.3 °C and the most intense rainfall was 40.3 mm/30 min. The long-term infiltration performance of the permeable asphalt shows that the overall infiltration capacity slowly reduces. The reduction can be hindered, but not completely prevented, with annual restorative cleaning. After two years of operation, the Climate Road still, by a large margin, fulfils the recommendations of the infiltration capacity of 97.2 mm/h for the vast majority of the road section. The total volume reduction capacity is estimated to be between 15 and 30%. Based on an analysis of 61 single rain events, the event detention time is found to range between 10 and 130 min, with an average of 35 min. During the project period, the Climate Road produced a total of 98 MWh for a nearby kindergarten, with an average coefficient of performance (COP) of 3.1.
