“…Natural processes include hydrometeorological hazards such as tropical cyclones, storms, and high rainfall, while human activities include dam failure and land conversion [1,2]. The global impact of flooding is a disruption of life and the economy in exposed areas [3,4]. Furthermore, it is influenced by the intensity and frequency of hazards/threats and vulnerabilities in flood-prone areas.…”

Vulnerability analysis toward river flooding in the Comal Watershed, Indonesia

et al. 2021

River flooding is a disaster that almost every year hits the downstream Comal watershed. This incident resulted in material, psychological, and even casualties. Therefore, a vulnerability analysis is needed to reduce the impact of flooding. This study aims to analyze the vulnerability to river flooding in the downstream Comal Watershed area, Indonesia. Vulnerability variables used are social, economic, physical, and ecological (environmental) vulnerability following the Indonesian National Disaster Management Agency (BNPB) Regulation 2012. Data were obtained from government agencies and interpretation of SPOT 5 satellite imagery. Data analysis were carried out using scoring and weighting. Moreover, the data classification were using the mean and standard deviation equations. The analysis showed that the vulnerability to river flooding in the Comal watershed area was dominated by a moderate vulnerable class of 10,832.15 hectares (49.69%) and distributed in 26 villages. Furthermore, the high level of vulnerability also covered a large area by 8,773.11 hectares (40.24%), and distributed across 29 villages. Therefore, proper river flooding mitigation planning with the characteristics of the area is needed.

“…in India, the primary state out of the 3 States from where the River passes, are highly vulnerable to floods. As characterizing vulnerability remains the critical challenge to improving flood risk analysis and management (Balica & Wright, 2009;Chen et al, 2019;Jiménez et al, 2020), the present study focuses on the assessment of flood vulnerability in the 21 districts, lying in the Narmada river basin of the state of Madhya Pradesh, India. Moreover, the novelty of this paper is to put forth the DEA-based vulnerability assessment framework for the Narmada river basin of Madhya Pradesh and procure more sentient results related to flood management.…”

Flood vulnerability assessment using data envelopment analysis – the case of Narmada river basin districts in central India

2021

This paper presents a Data Envelopment Analysis (DEA) based framework for estimating the flood vulnerabilities in River basins. The methodology has been exemplified for the 21 districts of the Narmada River basin in central India. Sensitivity and adaptive capacity indicators have been identified and used for the development of the Flood Vulnerability Index (FVI). DEA based study was employed to assess the Scale Efficiencies and the Returns to Scale and insights drawn from the analysis have been discussed in the context of policy and planning related to reduction of flood vulnerabilities. Cluster analysis has also been deployed to classify districts in terms of flood vulnerabilities. Results from the flood vulnerability assessment model case study indicate that 76% of the districts in the Narmada River Basin remain highly vulnerable to flood-risk, while the socio-economic parameters and physical sizes of districts and their resources play a crucial role.

“…In order to effectively achieve the purpose of flood fighting and disaster relief, to accurately analyze and evaluate the possibility of flood disasters and possible losses, and to better formulate disaster prevention and mitigation countermeasures and measures, flood disaster risk research is particularly important [2][3][4]. In recent years, a large number of scholars at home and abroad have carried out a lot of research work on flood disaster risk assessment and zoning [5][6][7][8] and established a set of more mature flood disaster risk assessment methods. Huang Guoru et al [9] summarized the application status, scope of application, advantages and disadvantages of the four flood risk assessment methods; Wu Shuqi et al [10][11] established a flood disaster risk assessment model in Zhejiang Province at the county scale for comprehensive evaluation and analysis.…”

With the continuous acceleration of the urbanization process, the flood problem seriously affects the economic and social development of the city and the daily life of citizens. Therefore, taking Linyi City as an example, the flood disaster risk assessment is carried out, the Linyi City flood disaster assessment index system is constructed, and the methods of mathematical statistics, analytic hierarchy process and spatial overlay analysis are used to calculate the environmental sensitivity of Linyi City flood disasters with the help of GIS technology. , Risk of hazard factors, vulnerability of hazard-bearing bodies, disaster prevention and mitigation capabilities. The research results show that the hazard levels of flood disasters are increasing from west to east, and high-risk areas are distributed in Feixian and Junan counties; sensitivity is affected by topography and gradually increases from north to south; Lanshan District, Luozhuang District, etc. The city center is highly vulnerable due to its significant population and economic status, and has strong disaster prevention and mitigation capabilities.
