What are the factors to be considered during flood vulnerability assessment?

What are the factors to be considered during flood vulnerability assessment?

Vulnerability is considered in the study of Flood Vulnerability Index (FVI) as the extent of harm, which can be expected under certain conditions of exposure, susceptibility and resilience.

How can we reduce flood vulnerability?

FIGURE 6-1 Examples of tools and measures to reduce and transfer flood risk in flood-prone areas….MITIGATION AND RISK TRANSFER MEASURES.

Structural	Nonstructural
Levees	Structure elevation
Floodwalls	Natural systems
Seawalls	Risk mapping
Dams	Hazard forecasting, early warning systems, and emergency plans

What is the vulnerability assessment formula?

However, most of the literature characterizes vulnerability according to the basic formula: Risk + Response = Vulnerability, or, as articulated in Holzmann et al.’s guidelines on the Household Economy Approach (2008), “Baseline + Hazard + Response = Outcome (v).”

How do we measure vulnerability in disaster management?

Physical Vulnerability may be determined by aspects such as population density levels, remoteness of a settlement, the site, design and materials used for critical infrastructure and for housing (UNISDR). Example: Wooden homes are less likely to collapse in an earthquake, but are more vulnerable to fire.

What are the vulnerabilities of flood?

In the context of flood, vulnerability is the extent to which a system is susceptible to flood due to exposure, a perturbation, in conjunction with its ability (or inability) to cope [2].

What are the solutions to flooding?

Flood control infrastructure, such as levees, seawalls, and tide gates, work as physical barriers to prevent areas from flooding. Other measures, such as pump stations and channels, help reduce flooding.

How do you perform a vulnerability assessment?

1. Step 1: Conduct Risk Identification And Analysis.
2. Step 2: Vulnerability Scanning Policies and Procedures.
3. Step 3: Identify The Types Of Vulnerability Scans.
4. Step 4: Configure The Scan.
5. Step 5: Perform The Scan.
6. Step 6: Evaluate And Consider Possible Risks.
7. Step 7: Interpret The Scan Results.

What are the 6 Disaster Risk Factors?

Lesson 6: Risk Factors Underlying Disasters

• Climate Change. •
• Environmental Degradation. •
• Globalized Economic Development. •
• Poverty and Inequality. •
• Poorly-planned and Managed Urban Development. •
• Weak Governance. •

Which are the most vulnerable House to flood?

Answer: The most vulnerable homes due to flood are (i) Buildings which are constructed with earth-based materials or using stone and brick in mud mortar are highly vulnerable to damage in heavy rains and/or floods.

How are vulnerability maps used in flood risk assessment?

A flood vulnerability map was also produced using a Fuzzy Analytic Hierarchy Process (FAHP), which considered the role of urban districts. Another component of risk flood assessment is the production of urban flooding maps and the prediction of flood-prone areas.

How is machine learning used in flood risk assessment?

Complimentarily, the use of machine learning (ML) techniques in flood risk assessment is growing due to their ability to capture relationships efficiently ( Wang et al. 2015) as the assessment depends primarily on detecting the flood-prone areas using historical events and topography ( Costache & Zaharia 2017 ).

Which is the most important factor in flood risk?

Maximum entropy approach was used to produce urban flood hazard map. Population, urban texture and distance to channels are the most important factors in flood risk. The vulnerability of an urban neighborhood greatly increases the risk of flooding.

Which is the best algorithm for flood classification?

Comparative assessment of ML algorithms to identify the most suitable algorithm for Greater Hyderabad Municipal Corporation (GHMC), India, to classify locations as either flooded or non-flooded.
