TECHNOLOGY DEVELOPMENT FOR AMPHIBIOUS STRUCTURES FOR FLOOD RESILIENCE Share

Amphibious structures are the type of structures that will float along with the flood level. In the initial stage, the structure will be resting on the ground. But when the flood level goes on increasing, it is planned to lift the superstructure along with the flood level. At that time, to keep the structure in position, an arrangement of pistons is proposed which will hold the building in position and also provide some flexibility to float on the water. This will be in a stable position by using the same principle as the ship is still in a position with anchors into the water when it is not moving. The platform on which the structure lies can be treated as the water pontoons. Based on the present records, these structures can be designed to float up to a height of 2 floors which is 8 – 10 meters. This type of structure will decrease the damage to the structure as well as the lives of the people during the disaster.  For testing, a model house of 1bhk house is prepared with its maximum dimension as 0.4 meters as the model testing is done in the container of size 1.2*1.2*1.0 meters. This was tested for various conditions based on our requirements. The proof of concept and feasibility of research is established at NITK from preliminary model tests. Now we propose to escalate the TRL to 6 through large model testing and standardize the technology for real field applications.
