“…Intercepting the infiltration of rainwater road surface generates higher runoff than agriculture, forest or any other natural land cover (Ziegler and Giambelluca, 1997; Ziegler et al, 2000). An event-based experimental study shows that the surface runoff coefficient for paved and unpaved roads are >90% and ~80%, respectively, which is only 0%–20% in the agricultural fields, therefore the lower depth of rainfall is adequate to produce overland flow and subsequently increase soil erosion (Hou et al, 2020; Ziegler et al, 2000). The insufficient penetration of rainwater by impervious road surface also affects the process of sub-surface flow and groundwater recharge (Wemple and Jones, 2003), and the consequent result shows by severe water shortage, flooding, and waterlogging conditions in the urbanised area with a higher density of paved road (Gu et al, 2018; Kramer, 2013; Xiong, 2016).…”

Transport network infrastructure interacts with the earth’s surface because they often share common spaces (e.g. river valleys), such that transport is an anthropogenic pressure that can affect geomorphological processes and outcomes. Since having its profound effect worldwide, the systematic study on the effect of transportation infrastructures (TIs) on the alteration of geomorphological forms and processes has been less focused than on any other anthropogeomorphic driver. The present review provides a multidimensional overview based on the available literature and data on the effect of TIs in changing hillslope and fluvial geomorphology to sustain a peaceful harmony between the transport network and its surrounding landscapes. The study underlines the effect of major TIs like trails, roads, railways, tunnels, causeways, waterways and airports on the alteration of different geomorphological processes on hillslope and fluvial landscapes like the movement of earth material, geomorphic connectivity, slope instability, sediment production, gully initiation and surface runoff. For instance, the global level proximity analysis shows ~40% of landslides happen within the 500 m of any major roads only, while at the regional scale it becomes ~65% irrespective of the degree of seismicity. Due to the fast development of TIs, the mountain regions are more prone to slope instability because of the alteration of surface hydrology by increasing runoff, road and ditch guided concentrated flow, rills and gully formation by reducing drainage area to cross the critical threshold limit. The plain regions are primarily facing the problem of fluvial (dis)connectivity because of the close proximity between river and transport networks and undersized causeways. For sustainable TIs development, factors like the practice of bio-engineering for roadside slope management, de-culverting, 100-year flood return for causeway construction, mapping of river corridors, road water harvesting should be incorporated for less effect on hillslope and fluvial geomorphology.

This paper describes the investigation of permeable road as a mitigation measure for urban flooding. The study involves the reconstruction of a historical case of inundation, namely the 11 December 2019 flood event along the Tong Wei Tah Street in Greater Kuching City, Sarawak, Malaysia. The Storm Water Management Model version 5.0 was used as the platform to describe the flooding at the selected site and the functionality of permeable road to alleviate flooding. A permeable road with a dimension of 200 m long, 6 m wide and 1 m deep was simulated along the whole stretch of Tong Wei Tah Street. The model results show that flooding was caused by a backwater effect in the drainage system. Models predicted 0.1 to 0.5 m flood depths which matched the observed 0.3 m flood depth account of a local resident. The permeable road exhibited capability to absorb all the out-of-drain floodwaters, leaving no water due to the 11 December 2019 flood on the street. Modelling efforts demonstrated that the floodwater hydrographs in the drain rose and fell within 7 h, while the underground storage, filled and drained within 13 h. Moreover, the storage of permeable road was found to fill up to 75 %, reserving the unfilled 25 % for adverse weathers. HIGHLIGHTS It was demonstrated in the case study of Tong Wei Tah Street that waterproof tarred road could be changed to permeable road that consists of permeable pavement layer and underground storage as urban flood mitigation strategy Through modelling efforts of a flooding event along Tong Wei Tah Street and its associated drainage systems, any spill of running water from the urban drains could be directed to the permeable road for temporary storage and conveyance It was found that floodwater on the road could be adsorbed by the permeable road structure itself, and as such, lessening the hydraulic burden of urban drains GRAPHICAL ABSTRACT

Permeable pavements can effectively reduce the urban road surface temperatures. To study the cooling effect of holding water on the road surface under the comprehensive influence of the external water and heat environment, a numerical model established by a finite element analysis software and an indoor test were used to verify the temperature change behavior of the road surface under different heating temperatures and holding water conditions. The results show that the average error between the numerical model and indoor test is 3.5%, and the model reliability is high. Under the same conditions, the change in thickness of the permeable pavement surface and base course has a negligible effect on the temperature of the road surface. For every 100 J/(kg/°C) increase in the specific heat capacity of the upper surface course and lower surface course, the maximum daily road surface temperature can be reduced by approximately 2.1°C and 0.4°C, respectively. The road surface temperature shows a similar pattern when the thermal conductivity increases. Under dry conditions, the maximum daily road surface temperature can be reduced by approximately 3.4°C and 4.3°C for surface-permeable and fully permeable pavements, respectively. This study provides reference suggestions for optimizing the selection and design of urban road pavement structures from the perspectives of permeable pavement design, material parameters, and structure type.
