Published: Feb. 8, 2023

This study aims to provide a framework analyse future flood scenarios considering the effects of three main drivers aggravation: climate change (rainfall intensification and sea level rise); unplanned urbanization; poor maintenance urban drainage systems. These stressors were chosen because they represent aggravation natural phenomenon, sprawl degradation system. analysis intends make it clear what increasing risks are. Subsequently, uchronic scenario is developed how adequate planning infrastructure provision can contribute sustainable resilient city regarding alleviation. The method supported by hydrodynamic simulation. Results demonstrate that precarious growth without providing coverage be even more dramatic than change.

The identification and classification of flood-prone areas comprise a fundamental step in the Flood Risk Management approach, providing subsidies for land use planning, floodproofing policies, design mitigation measures early warning systems. To address this issue, frequently used preliminary tool is flood susceptibility mapping region using range widely available data. Therefore, present study introduces an index-based approach able to qualitatively assess areas, named Physical Susceptibility Floods Index (PhySFI), based on multi-criteria decision-making method developed GIS environment. methodology presupposes critical discussion variables commonly other indexes, intending simplify proposed representation, emphasizes role user/modeler. PhySFI composed just four indicators, physical parameters assessed This index was first applied city Rio de Janeiro, as part Janeiro Climate Change Adaptation Plan. validation process comparative analysis with extent height simulated by hydrodynamic modeling watersheds within area, different urbanization processes each one. results indicate that powerful coastal cities.

MODCEL-MHUS: a comprehensive multilayer hydrodynamic unified simulation for stormwater, sanitary sewer systems, and urban surface

Water Science & Technology, Journal Year: 2024, Volume and Issue: 90(1), P. 190 - 212

Published: July 1, 2024

Numerous countries and regions have embraced implementing a separate sewer system, segregating sanitary storm sewers into distinct systems. However, the functionality of these systems often needs to improve due irregular interconnections, resulting in mixed malfunctioning system. Sewage collection is crucial for residential sanitation, but untreated significantly contributes environmental degradation. Analyzing simultaneous operation both becomes vital effective management. Using mathematical tools precise unified diagnosis prognosis imperative. municipal professionals companies need more specifically designed evaluate way, mapping all hydraulic connections observed practice. This study proposes simulation method stormwater urban systems, addressing real-world scenarios potential interferences. The primary goal develop considering system interconnections layouts, involving hydrodynamic water quality simulations. practical application this method, Multilayer Hydrodynamic Simulation Method (MODCEL-MHUS), successfully identifies issues networks suggests solutions, making it valuable tool management engineering professionals.

Elevating Pakistan’s flood preparedness: a fuzzy multi-criteria decision making approach

Financial Innovation, Journal Year: 2024, Volume and Issue: 10(1)

Published: Aug. 21, 2024

Abstract In South Asia, Pakistan has a long and deadly history of floods that cause losses to various infrastructures, lives, industries. This study aims identify the most appropriate flood risk mitigation strategies government should adopt. The assessment in this is based on certain criteria, which are analyzed using fuzzy full consistency method. Moreover, evaluated by weighted aggregated sum product (WASPAS) method, considering previously prioritized criteria. According results, lack governance , funding resources control infrastructure significant intensifying factors act as major criteria for assessing Pakistan. Adopting hard engineering (e.g., dams, reservoirs, river straightening dredging, embankments, relief channels) maintaining existing infrastructure, adopting soft (flood plain zoning, comprehensive assessment, sophisticated modeling) identified top three WASPAS highest weight (0.98) was assigned adoption mitigate risks. introduces novel dimension analyzing real-time impact unprecedented 2022 floods, during approximately one-third nation submerged. focus recent highly event enhances study’s relevance contributes unique perspective literature management. recommends prioritize effective mitigation. It also incorporate these national policy framework reduce future.

Conceptual framework to incorporate drainage solutions in the urban open space system

Frontiers in Water, Journal Year: 2024, Volume and Issue: 6

Published: Oct. 2, 2024

Cities are increasingly dealing with challenges regarding the negative impact of rapid and mismanaged urbanization. Therefore, city planning must cope natural environment limitations, seeking a balance between human activities well-functioning hydrologic cycle. This work aims to present conceptual framework able properly integrate stormwater dynamics into open spaces system in functional way, establishing Hydrological Interest Area, HIA, structure urban expansion integrated respecting watershed processes. The initial step is define primarily consisting that can be used for supporting drainage functions order land use process. delimitation offers background interpreting three arches, especially covering upstream, mid-reach downstream areas basin, guiding design set flood mitigation interventions focusing on Blue-Green Infrastructure. To illustrate validate proposed methodological framework, evaluated by modeling tool, using hydrological-hydrodynamic cell-model. A case study was driven Bambu Watershed, rapidly developing area municipality Maricá, Rio de Janeiro, Brazil. intervention includes an scenario low development behavior alongside four parks: upstream park reservoirs, two multifunctional floodable parks, dedicated lagoon restoration. plan complements riverbed modifications designed enhance water discharge. simulation showed significant reduction depths consequent decrease exposure buildings roads, most critical region watershed. highlights importance approach serves as robust foundation controlling proposing projects.

Abstract Communities have been menaced by floods for ages. Geographically, South Asia is one of the most flood prone regions world. In Asia, particularly Pakistan has long and deadly history causing losses to various infrastructure, lives, industries. Over last two decades, frequency severity events increased adversely affected livelihood well-being millions people in Pakistan. Therefore, nation must develop appropriate risk management policies procedures. The purpose this research study identify mitigation strategies that government should adopt reduce risks. evaluation these reduction based on specific criteria. Those criteria are gauged Fuzzy Full Consistency Method (FUCOM). Moreover, evaluated using Weighted Aggregated Sum Product Assessment (WASPAS) method, considering previously prioritized According results Lack Governance , Funding Resources Flood Control Infrastructure significant intensifying factors act as assessing strategies. Whereas Adopting Hard Engineering Strategies (Dams, Reservoirs, River Straightening & Dredging, Embankments Relief Channels) Maintaining Existing Soft (Floodplain zoning, Comprehensive Flood-Risk-Assessment, Sophisticated Modeling) identified viable top three WASPAS analysis. highest weight i.e., 0.98 was assigned adoption a hard engineering strategy.
