Tsunami house
Encyclopedia
A tsunami-proof building is a purposefully designed building which will, through its design integrity, withstand and survive the forces of a tsunami
wave or extreme storm surge
. It is hydrodynamically
shaped to offer protection from high waves.
An example of such an architecture is where a laminar flow
around a building will protect the walls. The structure can also rest on a hollow masonry block that for example can hold a body of water to sustain a family. A design can include battered walls, cantilever
steps and a wooden superstructure with the walls jutting out. Bamboo ply panels can be added to cover the sides.
A structure like this, concomitant with its mechanical strength, will provide its occupants with independent potable water storage for an extended period of time. The first example known has been constructed at Poovar
Island in southern Kerala

Tsunami
A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake...
wave or extreme storm surge
Storm surge
A storm surge is an offshore rise of water associated with a low pressure weather system, typically tropical cyclones and strong extratropical cyclones. Storm surges are caused primarily by high winds pushing on the ocean's surface. The wind causes the water to pile up higher than the ordinary sea...

In physics, fluid dynamics is a sub-discipline of fluid mechanics that deals with fluid flow—the natural science of fluids in motion. It has several subdisciplines itself, including aerodynamics and hydrodynamics...

Laminar flow
Laminar flow, sometimes known as streamline flow, occurs when a fluid flows in parallel layers, with no disruption between the layers. At low velocities the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards. There are no cross currents...

Cantilever
A cantilever is a beam anchored at only one end. The beam carries the load to the support where it is resisted by moment and shear stress. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs.This is in...

Poovar
Poovar is a small coastal village in the Trivandrum district of Kerala state, south India. This village is almost at the southern tip of Trivandrum and there is only one last village Pozhiyoor which mark the end of kerala. This village has a beautiful beach which attracts tourists. There are also...
