Quantitative flood hazard assessment methods: A review

Journal of Flood Risk Management, Journal Year: 2022, Volume and Issue: 16(1)

Published: Oct. 19, 2022

Abstract Flood hazard assessment is a fundamental step in flood risk mapping. Quantitative requires hydrodynamic modelling of the flooding process order to calculate spatial distribution suitable indicators representative intensity and frequency, hence its potential result harm. are usually defined by combining relevant parameters, mainly depth flow velocity, but also arrival time, duration, sediment or contamination load, so forth. A classification commonly introduced assign level areas potentially subject flooding. This article presents systematic review quantitative methods proposed scientific literature prescribed government authorities assess associated with natural anthropic listed compared specifying their underlying approach (heuristic, conceptual, empirical), exposed element which they were designed for (people, buildings, vehicles, etc.), fields application (river overflow, dam‐break, levee breach, debris flow). Perspectives future challenges analysis discussed. aims help modellers practitioners select most method case study interest.

An overview of flood risk components: The Land subsidence case of Pekalongan City

E3S Web of Conferences, Journal Year: 2024, Volume and Issue: 513, P. 01001 - 01001

Published: Jan. 1, 2024

Pekalongan City is located on the northern coast of Java Island, where climate crises, floods, and tidal waves pose significant threats exacerbated by rising sea levels land subsidence. This study aims to mitigate flood future losses emphasizes its potential as input for Indonesian regulators enhance current hazard classifications. conducts a comprehensive risk analysis, emphasizing detailed review classification quantitatively with mapping. The results showed mapping, comparing NDMA, MPW, proposed classifications, indicates tendency MPW overestimate hazards, particularly categorizing depths 0.5 m above “High”. depth according subsidence produces inundation area 14,145 Ha. shows that recorded in mapping can increase overall level. velocity classification, balancing NDMA’s underestimation MPW’s overestimation, offering more approach.

Risk analysis of debris and non-debris flow in the Cisokan river flood event

E3S Web of Conferences, Journal Year: 2024, Volume and Issue: 479, P. 03004 - 03004

Published: Jan. 1, 2024

Cisokan River is one of the main inflow rivers Cirata Reservoir aside from Citarum River. second largest contributor to after In May 2023 experienced instances flash flood disasters that submerged houses in Cianjur Regency, affected villages Ciranjang Village. Several news outlets reported this also left debris and mud areas, which indicated was flow. This study conducts risk analysis resulting non-debris flow with changes river cross-section due sedimentation. study, modeling carried out employing a Digital Elevation Model (DEM) map utilizing Hec-RAS software. One focus on simulating Newtonian (non-debris) non-Newtonian (debris), comparing results analyzing both. The result showed flow’s inundated area larger than flow’s, means high 12.5% area.

Application of a fuzzy, indicator‐based methodology for investigating the functional vulnerability of critical infrastructures to flood hazards

Journal of Flood Risk Management, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

Abstract Hazard vulnerability assessment of critical infrastructures (CIs) is crucial for ranking based on their level criticality, enabling the urban managers to prioritize CIs allocating funds in hazard mitigation/recovery process. This study aims provide a framework rapid and preliminary flood by introducing methodology classifying according riverine flooding. An indicator‐based curve calculated both quantitatively (using Fuzzy Logic Toolbox MATLAB) qualitatively susceptibility–exposure matrix), which prioritization accomplished with focus functional considering structural/nonstructural damages. Besides, this addresses consequences that damaged infrastructure may have rest estimates given additive impact surrounding failed interdependence. The was applied Berat (Albania) Sarajevo (Bosnia‐Herzegovina) findings compared those multi‐criteria decision‐making‐based approach commonly used CI literature. obtained results from methods represent roads are most vulnerable studied case Berat, while regarding city Sarajevo, road considered least floods bridges schools.

Enhanced Flood Adaptive Capacity Through a Growth Mindset

IGI Global eBooks, Journal Year: 2025, Volume and Issue: unknown, P. 231 - 278

Published: March 14, 2025

This chapter examines the transformation of a Northeastern Thai flood-affected hamlet, Ban Tha Khaek in Nakhon Phanom, using growth mindset—the belief that adversity like chronic floods may enable learning and adaptation. Villages used to flee floods, relying on outside aid lacking infrastructure. Community leaders, local administrations, educational initiatives helped town move from reactive proactive flood risk management. Flood forecasting, flood-resistant agriculture, collaborative water storage are non-structural adaptations. These methods have community manage sustainably, reducing infrastructure costs promoting ecological social cohesion. Integrating traditional knowledge participation has built resilience. case study shows how mindset individuals perceive as opportunities for improvement rather than inevitable disasters. It promotes engagement, education, anticipatory planning reduce climate-induced floods.
