3.2. Scientific vs. Perception Approaches

When this is the flood hazard map of the extreme and there is given the threshold values of 0.5 to 1.5 meter depth of inundation there is inundation map and if you can see that this whole region is completely flooded right about 1.5 meter height of inundation.

This chunk explains the flood hazard mapping, indicating the different levels of inundation. The flood hazard map shows how deep water can rise during a flood, with thresholds set between 0.5 to 1.5 meters. In a serious flood event, this map illustrates that the entire region can be submerged when water levels reach around 1.5 meters.

Imagine if you live in a neighborhood where a particular road is prone to flooding. The flood risk map would guide you in understanding at what point your road might be underwater during heavy rains. Just like knowing where to place your furniture during a flood can protect your belongings, flood maps help communities prepare.

When we talk about physical vulnerability what are the places which has been in highly damaged, medium damaged, and the low damaged and which has been not defined.

This chunk focuses on categorizing physical vulnerability into three classes: highly damaged, medium damaged, and low damaged. This classification helps to identify which structures and areas are at greater risk, informing decisions on rehabilitation and resource allocation during disaster response.

Consider this like examining a car after an accident. If the front is crumpled extensively (highly damaged), the back has minor scratches (medium damaged), and the tires are fine (low damaged), prioritizing repairs becomes clearer. Similarly, understanding which areas are more affected helps emergency teams act quickly.

This is the social vulnerability map. The target groups which are actually which are the most of these communities which are often affected.

In this part, the text introduces social vulnerability mapping, which focuses on identifying communities most at risk during flooding events. This map outlines which groups have limited resources or preparedness, guiding where aid should be directed.

Think of this mapping as assessing which friends might need help the most when organizing a group outing. Just as you would check who might be struggling with transport or finances, social vulnerability mapping helps identify those communities needing the most support during disaster recovery.

When we say economic vulnerability, when the flood happens obviously what kind of business sector often closes down, shuts down for a period of some time.

This chunk addresses economic vulnerability and how flooding impacts businesses. It highlights that certain sectors may shut down or suffer heavily during floods, impacting both the local economy and those who depend on these businesses for their livelihoods.

Imagine a small café in a flood-prone area. After a flood, the café might have to close for weeks due to water damage and equipment loss. The owner not only loses income but also has to lay off staff, affecting their families. This demonstrates how interconnected the community's economic well-being is with environmental conditions.

And you can see that you know much of the cultural properties are under the high risk. And this is where one has to understand that the heritage which is UNESCO world heritage it is subject to the high risk.

This part elaborates on the cultural vulnerability of heritage sites, particularly those recognized as UNESCO World Heritage Sites. It emphasizes the importance of preserving these sites for future generations and notes that they are at significant risk during flood events.

Think of cultural heritage as an ancient library filled with irreplaceable books. If a flood threatens to destroy this library, the loss would be immense, as future generations would lose access to this vital knowledge. Protecting cultural sites is akin to safeguarding our history and identity.

Now what they did was they tried to combine this map and one is using all the digital tools how they combined and this is again a combined flood risk map by a traditional approach.

This piece discusses the effort to combine scientific data with community perceptions to create a comprehensive flood risk map. It highlights the strengths and weaknesses of both approaches, suggesting a synergistic method can yield more effective disaster preparedness plans.

Think of it like a team project in school, where one student excels in research (the scientific data), while another has great insights based on family experiences with floods (community perception). By merging both perspectives, the project becomes more robust and informative, better equipping the class to understand the topic.
