Exploring the Interdependencies Between Transportation and Stormwater Networks: The Case of Norman, Oklahoma

Transportation Research Record Journal of the Transportation Research Board, Journal Year: 2023, Volume and Issue: 2678(5), P. 491 - 513

Published: Sept. 13, 2023

The significance of critical infrastructure systems in maintaining productivity is undeniable. However, such remain susceptible to external disturbances and cascading failures. Instead operating independently, these physical systems, as transportation stormwater form an interdependent system. This interdependence, particularly important during flooding, illustrates that the failure a system can disrupt traffic networks. To explore extent interdependency, this study investigates networks Norman, Oklahoma. Using network science theories concepts multilayered networks, paper analyzes both individually combination. identifies closely located components road using Moran's I spatial autocorrelation metric. Next, connectivity represented graph format investigate topological credentials (i.e., rank relative importance) water inlets, intersections nodes, conduits, segments links). Moreover, further change by considering weights average daily traffic, flow). proximity-based considerations between utilizing score revealed good indicator interdependency. When incorporating directionality, multilayer analysis highlights highly central tend cluster spatially, unlike undirected counterpart. also vulnerable locations combined setting differ from isolation. In doing so, research reveals new insights governing complex reliance on neighboring systems.

Coupling Coordination Research on Disaster-Adapted Resilience of Modern Infrastructure System in the Middle and Lower Section of the Three Gorges Reservoir Area

Sustainability, Journal Year: 2022, Volume and Issue: 14(21), P. 14514 - 14514

Published: Nov. 4, 2022

Rapid incremental urbanization in China has resulted an incomplete modern infrastructure system and multiple point-like flaws. This is due to a lack of funding poor scientific construction concepts procedures. also contributes the system’s low disaster-adapted resilience insufficient coupling coordination production-oriented service-oriented subsystems. Based on “Robustness-Rapidity-Redundancy-Resourcefulness-Durability” (4R-D) frameworks, this study screens 53 indicators across three tiers “production-oriented, service-oriented, intelligent” subsystems establish evaluation system. We examined overall development among Three Gorges Reservoir Area (TGRA) from 2009 2020 using degree model (CCDM). Grey relational analysis (GRA) was used analyze significant control aspects based grey theory. The findings show following: (1) at macro level resilience, each subsystem, research region upward trend 2020, with rise 2018 being most significant; (2) micro level, 2010 2013, there no obvious spatial divergence 2014 driven by radiation two major urban agglomerations, Yiling Wanzhou both more substantial increase, while rest counties have small increase; (3) meso seven factors impact coupled coordinated than other indicators, including rate, average annual rainfall, number health technicians per 10,000 people, percentage GDP tertiary industrial sector.

Resilience Assessment in Urban Water Infrastructure: A Critical Review of Approaches, Strategies and Applications

Published: June 19, 2023

Resilient urban water infrastructure (UWI) is essential to maintaining public health and safety in areas preventing consistent disruptions. However, UWI vulnerable a wide range of shocks stresses due the complex nature interdependency its components. The primary objective this study evaluate advances resilience assessment comprising supply, stormwater, wastewater systems. This involves examining bibliometric analysis, developed frameworks understand concepts for society, strategies improving resilience, indicators. findings indicate that has primarily been conducted countries, highlighting macroeconomic importance UWI. Three major were identified analysing UWI: system design, development concepts, implementation green infrastructure. It was also found while commonly defined based on technical approaches, more thorough understanding can be obtained through holistic approach. While such as upgrade, decentralisation, digitalisation, nature-based solutions enhance UWI, they may insufficient achieve all To address issue proper comparison different options, comprehensive qualified indicators metrics should extensively examined future.

Resilience Assessment in Urban Water Infrastructure: A Critical Review of Approaches, Strategies and Applications

Sustainability, Journal Year: 2023, Volume and Issue: 15(14), P. 11151 - 11151

Published: July 17, 2023

Urban water infrastructure (UWI) comprises the main systems, including supply systems (WSS), urban drainage/stormwater (UDS) and wastewater (WWS). The UWI needs to be resilient a wide range of shocks stresses, structural failures such as pipe breakage pump breakdown functional unmet demand/quality, flooding combined sewer overflows. However, there is no general consensus about resilience assessment these widely presented by various research works. This study aims critically review approaches, strategies applications for complex in UWI. includes examining bibliometric analysis, developed frameworks related help comprehend concepts specified settings, improving resilience, indicators common tools used modelling results indicate that has primarily been conducted countries, underscoring macroeconomic significance Three key areas have identified analysing UWI: system design, development implementation green infrastructure. Moreover, it discovered although commonly defined using technical more comprehensive understanding can gained through holistic approach. Furthermore, while upgrades, decentralisation, digitalisation nature-based solutions enhance they may insufficient fulfil all indicators. To address challenge effectively comparing different options, crucial extensively examine sustainability-based future research.
