“…This can be explained by the fact that peak reduction highly dependent upon the available soil storage, formation of LID practices, as well as the rainfall characteristics of the selected study region. The results of the LID practices are also in line with the pertinent literature; such that green roofs are shown as the feasible option among other LIDs by many scholars (Cristiano et al 2020;Arjenaki et al 2021). For instance, Arjenaki et al (2021) found green roofs more advantageous than permeable pavements and rain barrels as the green roof provides highest decrease rate in volume and discharge peak of runoff.…”

This study aims to investigate the effectiveness of the low impact development (LID) practices on sustainable urban flood storm water management. We applied three LID techniques, i.e. green roof, permeable pavements and bioretention cells, on a highly urbanized watershed in Istanbul, Turkey. The EPA-SWMM was used as a hydrologic-hydraulic model and the model calibration was performed by the well-known Parameter ESTimation (PEST) tool. The rainfall-runoff events occurred between 2012 and 2020. A sensitivity analysis on the parameter selection was applied to reduce the computational cost. The Nash-Sutcliffe efficiency coefficient (NSE) was used as the objective function and it was calculated as 0.809 in the model calibration. The simulations were conducted for six different return periods of a storm event, i.e. 2, 5, 10, 25, 50 and 100-years, in which the synthetic storm event hyetographs were produced by means of the alternating block method. The results revealed that the combination of green roof and permeable pavements have the major impact on both the peak flood reduction and the runoff volume reduction compared to the single LIDs. The maximum runoff reduction percentage was obtained as 56.02% for a 10-years return period of a storm event in the combination scenario.

“…These studies have been independent of the original developers (United States' Environment Protection Agency) and spanned a range of scales, climates, geologies, and urban extents. Furthermore, the introduction of new modules within the model has led to the inclusion of SuDS developments in recent simulations, too (see Arjekani et al 2020;Peng & Stovin 2017;Rosa, Clausen & Dietz 2015). For example, Chow, Yusop & Toriman (2012) 2016) study is concerned with a unit-scale analysing the long-term performance of a green roof feature, whilst Fu et al (2019) apply the model district-wide in China's Yizhuang district.…”

Urban hydrologyAppreciating the dynamics of the hydrological cycle in the urban domain requires consideration of both the natural water cycle and the manmade elements which interact with it, such as those for storage and conveyance (Barbosa, Fernandes & David 2012). Not only does this lead to more complex pathways through the cycle due to the increased number of elements involved, but creates challenges for data collection as often these manmade elements are owned by private companies, leading to uncertainties and difficulty in accessing information on channel (pipe) size and locations (Noh et al. 2016).In addition, the processes and storages of the natural water cycle are also altered in the urban domain, with potential for some being reduced (see Figure 1). For example, the increased impermeable surface area relative to an undeveloped parcel leads to reduced infiltration and evapotranspiration, with a resultant increase in surface runoff (Anim et al. 2019). Reduced infiltration into permeable, undeveloped land also leads to reduced groundwater level and less resilience of the land to prolonged dry periods.Management in the urban form usually results in attempts to control where the water is located, too, through the channelling of water into drains and pipes. This is then conveyed out of the populated area. Consequently, when the inflow is greater than the outflow (during intense and/ or persistent rainfall), problems are exacerbated as there is little storage capacity and water collects in these areas.As a result, the spatial and temporal scale of the subprocesses in the hydrological cycle are much smaller in

“…Hydrological processes such as infiltration, evapotranspiration, and surface run-off are solved in a control volume of the discretized mesh of a study area. 26 [28][29][30] SWAT is an important and widely used model for simulating the hydrological processes on scales ranging from a small watershed to a river basinscale. The model can simulate the quantity and quality of surface as well as ground water in the study area.…”

Urban floods are paralyzing surface transportation and inflicting heavy economic losses. Climate-induced increase in frequency and intensity of rainfalls and excessive urbanization makes urban centers even more vulnerable to floods. It is necessary to quantify all dimensions of losses caused to road connectivity to improve flood mitigation policy. There is a need to consolidate the existing body of peer-reviewed contemporary literature on flood inundation modeling and its impacts on road connectivity. This will improve the awareness of policymakers and researchers and help in science-based decision making. Articles archived in the Web of Science database having the keywords floods and road in their title published between 1977 and 2020 were analyzed using the blibliometrix library of R. Analysis shows that the flood inundation and flood extent modeling has evolved from the conventional hydrological models to the near real-time crowd-sourced modeling methods. Applications of geographical information systems and advanced remote sensing methods have been growing in identifying road network vulnerabilities. We observed a gap in harmonized data availability, due to the unstructured data formats at several scales, which hinders a generalized approach for flood risk modeling studies for urban planning. Concentrated efforts have to be made to fill the gaps in data availability and research methodologies, especially using crowd-sourced data. Further, efforts have to be made to increase awareness, early warning systems, and alternate transport networks, to make the cities less vulnerable to floods.
