Extreme Flood Disasters: Comprehensive Impact and Assessment

Water, Journal Year: 2022, Volume and Issue: 14(8), P. 1211 - 1211

Published: April 9, 2022

Evaluating extreme flood disasters is a prerequisite for decision making in management. Existing disaster assessments fail to either consider or evaluate comprehensive impacts from social, economic, and environmental aspects. This study first analyzes the causes of subsequently potential consequences depth. On basis this analysis, an indicator system developed by taking into account consequences. To assess impacts, we propose refined social economic impact evaluation method semi-quantitative method, which are applied Jingjiang Flood Diversion District (JFDD) located Yangtze River Basin, analyze two scenarios. The results show that almost all JFDD area flooded with inundation areas 901.36 km2 879.49 km2, respectively. corresponding affected populations 0.51 million 0.5 million. direct losses 18.83 billion 14.33 billion, Moreover, 5 pollutant sources 11 protected inundated under Extreme floods have relatively serious on local ecology environment. proposed methodology can provide effective support makers.

Flood risk assessment for residences at the neighborhood scale by owner/occupant type and first-floor height

Frontiers in Big Data, Journal Year: 2023, Volume and Issue: 5

Published: Jan. 9, 2023

Evaluating flood risk is an essential component of understanding and increasing community resilience. A robust approach for quantifying in terms average annual loss (AAL) dollars across multiple homes needed to provide valuable information stakeholder decision-making. This research develops a computational framework evaluate AAL at the neighborhood level by owner/occupant type (i.e., homeowner, landlord, tenant) first-floor height (FFH). The values were calculated here numerically integrating loss-exceedance probability distributions represent economic building, contents, use. simple case study census block Jefferson Parish, Louisiana, revealed that homeowners bear mean $4,390 100-year elevation (E100), compared with $2,960, $1,590 landlords tenants, respectively, because homeowner incurs losses use, rather than only two three, as landlord tenant. results this showed FFH reduces proportionately each type, feet additional above E100 may most economically advantageous benefit. modeled suggested Hazus Multi-Hazard (Hazus-MH) output underestimates 11% building 15% contents. Application technique while partitioning types will improve planning improved resilience assessment impacts attributable costly hazard.

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.

Analyzing the Flood Intensifying Factors and Mitigation Strategies to Enhance the Flood Resilience in Pakistan: A Novel Hybrid Fuzzy-FUCOM-Fuzzy-WASPAS Approach

Research Square (Research Square), Journal Year: 2023, Volume and Issue: unknown

Published: Oct. 31, 2023

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. Afterwards, 0.5 strategy maintaining existing infrastructure 0.2 adopting soft approaches. Lastly, policy also recommended future.

RESIDENTIAL BUILDING FLOOD RISK ASSESSMENT AND THE BENEFITS OF HOME ELEVATION

Published: May 8, 2023

Evaluating flood risk is an essential component of understanding and increasing community resilience. A robust approach for quantifying in terms average annual loss (AAL) dollars needed to provide valuable information stakeholder decision-making inside outside the special hazard area (SFHA, which corresponds 100-year floodplain). To further inform mitigation strategies, reduction with home elevation above initial first-floor height (FFH0) cost effectiveness federal assistance are important steps enhance awareness effect reducing risk.
