Flood Impact Assessments on Transportation Networks: A Review of Methods and Associated Temporal and Spatial Scales

Abstract

A region's transportation sector is vital to its economic and social health. Transportation systems are also influenced by climate change directly and indirectly and on a variety of spatial and temporal scales. Under a changing climate, many regions around the globe and especially in urban areas, have experienced increases in flood intensity and frequency in recent decades. Flooding can strain transportation networks in both the short- and long-term through transportation delays, infrastructure damage, and recovery, and potentially affect economies. The present article is a review of how flooding impacts transportation networks in both short- and long-term timescales and their subsequent impact on resiliency of the network. Firstly, flood effects are classified based on the connections between the type of flooding and the type of impact (either direct or indirect) on the transportation system. An analysis of the assessment methods and the transport models used to formulate flood effects on the transportation system is provided, as well as the drawbacks from the context of timescales, and recommendations for future research. The analysis indicates that the majority of the articles assess the direct and tangible impacts with focus on the resilience of the transportation network in short- and medium-term temporal scales and at smaller spatial scales. There is less emphasis on indirect, intangible flood impacts, and long-term temporal scales.

Natural disasters and agricultural trade in China: analyzing the role of transportation, government and diplomacy

“…For the former, the agriculture value-added and transportation system show a significant mediating role in this effect. This outcome affirms Hypothesis 2 (H2) which is consistent with Godfrey et al (2019), Gray (2020), Kyriacou et al (2019), Rebally et al (2021) and Zhou et al (2021). For the latter, the government effectiveness and diplomatic relations signalize a considerable moderating role in the effects.…”

Equations ( 2) and (3) estimate the mediating role of transportation infrastructure, while Equations ( 4) and ( 5) estimate that of agriculture value-added.…”

Estimating the carbon footprint of post-flood urban road network restoration efforts: A case study in Carlisle

“…Implications of the integrated assessment model Climate change and increasing flood risks have posed potential challenges to societal sustainability (Devitt et al 2023). However, more attention tends to be paid to the economic losses arising from flood events than the environmental burdens (Rebally et al 2021). Flood disasters have a widespread impact on urban infrastructure, including road networks.…”

An Innovative Method in Measuring Permeability and Evaporation Parameters in Porous Pavements With Emphasis on Its Effects on Increasing Urban Transport Safety

“…Today, with the growth of population and urban development, climate change and the occurrence of floods, urban runoff control has become a serious problem in the field of urban management [1]. The occurrence of floods and the subsequent inundation of urban thoroughfares, in addition to disrupting urban transportation and reducing road safety, which is the most important feature of the road [2][3][4][5][6][7], has a negative psychological effect on lives in terms of visual beauty. Because the thoroughfares are very influential on the beauty of the urban texture and the moods of people, thus, the control and management of urban runoff are of special importance.…”
