Flood Resilient Architecture, An Innovative Way to Face Floods in The 21st Century

Floods have been a global issue for many years, affecting both humans and the environment. Architects luckily have developed a technique known as flood resilient architecture to mitigate the after-effects acknowledging that one of the most serious issues caused by floods has always been damaged residences and ruins.

With the water level overflowing far too frequently these days, the government is being demanded to find a way to implement this concept in local residences for a safer and better living environment. So, what’s in it with the flood resilient architecture?

Flood Resilient Architecture 101

Water will often flood through buildings causing damage to structures, furnishings, and fittings, as well as accumulating in porous materials such as masonry, pugging, or other insulation. These can then act as ‘moisture reservoirs,’ allowing for long-term damp and decay which will later then caused buildings to collapse.

What?

Flood resilient architecture are the techniques employed to reduce or eliminate the risk of future flood damage to structures.

Why?

The world’s earliest civilizations all arose in river valleys, and their livelihoods were primarily dependent on water. Water bodies, while being a carrier of nutrients and a protector of ecosystems, can cause immense and deadly floods that destroy people’s property and dreams. Architecture may not be able to completely prevent floods, but it can contribute to aiding damage and thus save lives.

Who?

The founder of flood resilient architecture remains unknown. Yet, some of concepts used are similar to the houses found in the maritime area where people live nearest to the water bodies.

Where?

This architectural technique is appropriate for any flood-prone area, residence, or even country to assist structures in remaining perfectly as they were before the flood. Various techniques are used to meet a variety of needs. As a result, it is critical to understand which features are required for a particular residence.

Examples of Flood Resistant Technique Worldwide

The following are examples of flood resilient architecture technique that can adapt to high water levels:

1. Wet Floodproofing

Wet floodproofing, as the title suggests, enables floodwaters to penetrate a house’s enclosed areas. According to A Better City, Wet floodproofing is the process of modifying a structure to allow an enclosed area below the base flood elevation (BFE) to flood by using openings (e.g. vents) or breakaway walls that are designed to drive free from the constructing when exposed to flood forces. Enabling the building to flood reduces internal and external hydrostatic pressure, helping to reduce loads on walls and floors and lowering the risk of structural damage.

2. Dry Floodproofing

Dry floodproofing refers to making a structure watertight below the level that requires flood protection in order to prevent floodwaters from entering. In dry floodproofing, there are two methods: Opposite from the wet floodproofing method, this technique does not allow water to seep into the structure, keeping it sealed and dry.

3. Elevated Buildings

Elevated buildings simply means that the structure is build with no lower floor and above the ground level. This concept has been used for many years even decades for the humankind to prevent nature dangers and tribe wars. Utilizing this method allows the house to stay dry at an elevated level.

Implementing these techniques across an entire residence may be a large project, as it requires a large budget and a lengthy process. However, if the government is successful, the financial risk associated with the flood aftermath will be reduced, and the community’s welfare will improve.
