Abstract. Bridges are critical-infrastructure components of road and rail transport networks. A large number these critical assets cross or adjacent to waterways floodplains therefore exposed flood actions such as scour, hydrodynamic loading, inundation, all which exacerbated by debris accumulations. These stressors widely recognized responsible for the vast majority bridge failures around world, they expected be due climate change. While efforts have been made increase robustness bridges hazard, many scientific technical gaps remain. were explored during an expert workshop that took place in April 2021 with participation academics, consultants, decision makers operating mainly United Kingdom specializing fields risk assessment management resilience. The objective was identify prioritize most urgent significant impediments In particular, following issues, established at different levels scales resilience, identified analysed depth: (i) characterization effects floods on typologies, (ii) uncertainties formulae scour depth assessment, (iii) evaluation consequences damage, (iv) recovery process after (v) decision-making under uncertainty flood-critical bridges, (vi) use event forecasting monitoring data increasing reliability estimations. issues discussed this paper inform other researchers stakeholders worldwide, guide directions future research field, influence policies mitigation rapid response warnings, ultimately

Sustainability and climate resilience metrics and trade-offs in transport infrastructure asset recovery

Transportation Research Part D Transport and Environment, Journal Year: 2023, Volume and Issue: 121, P. 103800 - 103800

Climate change exacerbates natural hazards and continuously challenges the performance of critical infrastructure. Thus, climate resilience sustainable adaptation infrastructure are paramount importance. This paper puts forward a novel framework metrics for optimising sustainability (Greenhouse Gas emissions - GHG), (restoration time), cost. The aims to facilitate decision-making by operators stakeholders communicate actionable trade-offs between these principles. It describes approaches quantifying ex-ante ex-post recovery from lenses using relevant metrics. concludes with an application on bridge, where normalised integrated into one unique index (ISRC), which can be used in prioritisation portfolios similar assets. optimisation program includes bridge recovery, while reducing GHG emissions. impact indexes is examined results show how optimum solutions adversely affected different projections. In all scenarios examined, more leading reduced (tCO2e) when weighing Based case study analysed this paper, low carbon restoration strategy resulted up 50% higher ISRC, justify investments strategies transport

Scour jeopardises the safety of many civil engineering structures with foundations in riverbeds and it is leading cause for collapse bridges worldwide. Current approaches bridge scour risk management rely mainly on visual inspections, which provide unreliable estimates its effects, also considering difficulties visually monitoring riverbed erosion around submerged foundations. Thus, there a need to introduce systems capable continuously evolution at foundations, even during extreme flood events. This paper illustrates development deployment system consisting smart probes equipped electromagnetic sensors. first application this type sensing real case-study continuous monitoring. Designed observe changes permittivity medium sensors allow detection depths assessment whether hole has been refilled.
