How can Buoyant Force of Water be a Solution to Flooding

April 29, 2021 | Created by: Andreas Klippe | Comments

After flooding, we see different objects floating on floodwaters. The buoyant force of water is causing these objects to float. But did you know that the same force can actually help solve flood problems? Read on and find out how.

To begin, we have to define what buoyant force is. 

The buoyant force is the upward force applied to an object. For instance, when you throw a bottle into an ocean, the bottle will float. Why? It is because of the upward force exerted onto the bottle called the Buoyant force.

The weight of a buoyant object dropped into the water is no match to the upward force exerted by the water. Some objects rise to the surface and float because their downward or gravitational force is much lesser than the water’s upward or buoyant force.


To float or not to float? That is the question. Since water is exerting a powerful force, do all objects float?

The answer is no. 

Rose DeWitt Bukater (of Titanic) is buoyant so she floated

Buoyant objects float on water and non-buoyant objects do NOT float. Usually lighter objects like a feather, a basketball, or an empty 500 ml bottle of water are buoyant. Heavier objects like rocks, bowling balls, laptops, or full 500 ml bottles are negatively buoyant. 


Now that you know what buoyancy is, we answer the question, “how can this force help solve flood problems?” 

To solve the problem of floods, many business owners and private residents are turning to German-engineered flood protection barriers. These flood barriers are made of marine-grade aluminum, hot-dipped galvanized steel, or stainless steel. They can be operated manually, semi-automatically, or automatically. 

All these flood barriers, regardless of the mode of operation, can give total protection to your property. However, you must consider the mode of operation especially when time is a factor. When there is a need to immediately protect the property, you need automatic flood protection barriers.

You must consider the mode of operation especially when time is a factor.

An example of an automatic barrier system is the Self-Activating Flip-Up Flood Barrier. This barrier is unique because floodwaters activate them. The force of the floodwaters activates the flip-up barriers, pushing them up. In other words, the buoyant force of the floodwater causes the barrier to rise.

Let me repeat that, the buoyancy of the flood is what activates the flood barrier!

No electricity? No problem. 

Got no time to deploy? Not a problem. 

No time for switches? No problem. 

Do not have enough manpower? Definitely not a problem. 

The buoyant force of the floodwater will solve the possible problem of flooding. And you? Well, you will have NO PROBLEM!

Self-Activating Flip-Up Flood Barriers are made of high-quality materials and absolutely watertight. They are certified by international norms, namely, the US-American FM Global and the German TÜV.


Flood is a big problem in countries with high rainfall intensity and those with low ones. The level of rainfall intensity is no longer an indicator of whether your area will be flooded or not. Everyone is vulnerable to flooding. 

However, even if flooding is dangerous, we can use it to turn the tide. The flood that used to damage properties will be the same flood that will catalyze the Self-Activating Flip-Up Flood Barriers! The German manufacturer ANHAMM invented such barriers and is a very successful technology.

You can just relax because the buoyant force of floodwaters will activate Self Activating Flip-Up Flood Barrier
