4.1 Analysis of results

Even though a Level 5 Catastrophic flood in real life comes at a rate of 3.6km/h, our house only managed to get 2.106km/h rate of rise.

Despite this, 95% of all floods to date are within the 1.5km/h range to the 2.5km/h range. Using only cheap recyclable materials, our house managed to survive under these conditions that would normally cause most houses to be destroyed.

This shows that our house was success and that it was able to put up to most of the stresses that a normal house would go through in a flood.


4.2 Key findings

Some of the key findings we made:

  1. Our house was able to perform under floods
  2. We were able to match the rate of rise of 95% of floods but we weren’t able to match the highest record.



4.3 Explanation of key findings

Our house did not get wet at all which shows that it was well protected from the flood. Moreover, we compared data we got from our simulated flood and compared it to real values in real floods. Our house was able to survive floods that would normally cause the destruction of many homes in real life.


4.4 Evaluation of engineering goals

Our engineering goals:


“Making an efficient mechanism to protect homes from floods and rising sea levels by rising up the house in accordance to the water level. It must meet the specific requirements show in 1.3. It must be able to rise up within the 3.6km/h rate of rise a Level 5 flood occurs at. It should be able to protect itself from small debris like rocks or branches that get swept away in a flood. It also should be made of cheap materials that can be easily obtained like PVC pipes or foam. “

Our specific requirements:

1. Make the house rise up with the rising water
2. Prevent the water from going inside the house
3. Protect the house from small debris.
4. Make the house rise itself at the speed of water level rise to protect it from water damage and flooding. For example, a usual flood rises at 3.6km/h [Is flow velocity a significant parameter in flood damage modelling?, 2009]  We aim to make our house match this rate of rise.

We were able to complete all of our engineering goals and and specific requirements except for part 4 of the specific requirements.

In part 4, we wanted our house to match the 3.6km/h rate of rise of the water in a flood. But our house only managed to match 2.106km/h rate of rise. However, we do not see this as a failure as 3.6km/h is a record of the highest rate of rise in a flood. 95% of floods that occur are within the 1.5km/h range and the 2.5km/h range. These floods cause enough damage to destroy countless homes and displace a lot of families. Our house managed to survive all this using only cheap recyclable materials


4.5 Areas for improvement


Given more time, we would like to make our project look nicer add some more functionality like a LCD display to show the water level
