Hydraulic Performance of Permeable Asphalt and Picp in Swmm, Validated by Laboratory Data

Abstract

Traditional urban development practices disrupt the natural water cycle, increasing surface runoff volume/velocity and reducing water quality, amongst other impacts. Those negative impacts can be reduced adopting sustainable urban drainage system (SUDS) techniques, such as pervious pavements. porous asphalt (PA) and permeable interlocking clay/concrete pavers (PICP) are two types of pervious pavements. Both are similar to traditional asphalt and pavers, but superficial layer has a high porosity for allowing infiltration of rain, and base/subbase layers contain a high void fraction to allow water retention. In order to analyse these types of pavements and assess how they affect the general urban stormwater network, the SWMM model has been widely used. Even so, more confidence in the selected parameters is needed, especially when modelling homogeneous areas by means of low impact development (LID) units. To do so, laboratory tests have been implemented using a rainfall simulator, testing PICP/PA materials under different slopes (1% and 6%) and rain conditions (35 mm/h and 70 mm/h), and infiltrated water was measured for each layer independently. This paper validates, using the aforementioned laboratory data, the parameters needed for modelling PA and PICP in SWMM, as well as differences between them, showing that SWMM is a convenient tool to model single events on permeable pavements for regular storms.

Review of the development and research of permeable pavements

“…From an environmental perspective, benefits in terms of hydrological indicators include reduced peak flow, decreased runoff volume, and delayed hydrograph. Reducing runoff volume and peak values can enhance rainwater infiltration into native soils, improving water quality, mitigating the urban heat island effect, and decreasing traffic noise (Madrazo‐Uribeetxebarria et al, 2023). Environmental benefits in terms of water quality manifest as potential for water treatment.…”

Sustainable Urban Drainage Systems (2014-2023) by Using Bibliometric Analysis Method

“…A conceptual framework is important for people's health because it lets us think critically about the long-term viability of cities, flood prevention, and the water cycle. For example, it helps with urban drainage, modeling rainfall-runoff, and designing cities that are sensitive to water (Madrazo-Uribeetxebarria et al, 2019). Additionally, the keywords in light orange for cluster (6), like" low impact development, engineering geology, sustainable stormwater management, and their capacity to adjust to changing circumstances in sustainable urban drainage systems, depend on green infrastructure for urban drainage design (Štrbac et al, 2023).…”

Green Urban (RE) Generation: A Research and Practice Methodology to Better Implement Green Urban Infrastructure Solutions

“…This paper considers green pavements both those that allow rainwater to infiltrate through the pavement's material and those in which rainwater infiltrates through the joints [64]. The research, hence, classifies them into two main groups: Permeable pavements due to their composition, which can in turn, be modular or continuous; and Pavements that are permeable at their joints, which can also be modular or continuous (Figure A4).…”
