Disaster Recovery and the Road Ahead - IGNOU

Technology used in ‘Chaukhats’
The technology applied on the ‘Chaukhats’ was like a machine stitch on a fabric that
keeps a piece of cloth in shape. In like manner, the technology made use of wood, like
a thread and kept the entire structure intact against the ravages of weather and geoactivity.
Through-stones and flat-stones were used, and wood predominated the structures
of whatever dimensions they were. Pairs of thick wooden logs, beginning from the base
of any two opposite walls were used at every 30 inches alternately with heavy stones to
raise the walls and run through the entire length of all the walls.

1.5.2 Rehabilitation after Cyclones
The principal dangers in case of a cyclone are from gales and strong winds, torrential rains, as well
as storm surges. Houses totally collapse during cyclones. Loose files fly off; metal fibre sheets also
fly away. In intense cyclones, whole roofs, even the cemented ones can fly off. Rehabilitation in
the aftermath of cyclones would mean total rebuilding of houses. Thus, attention needs to be paid
on:
Removal of salinity by washing the upper
soil through excessive irrigation.
Planting shelter belts/mangroves in coastal
areas.
Adequate connection between the roof
and external wall
Use of Mangalore titled roofs
Anchoring of tiles along the ridges, cave
and roof intersections
Monitoring of corrosions, cracks and
leaks in houses all through the season
1.5.3 Rehabilitation After Floods
In floods aftermath, Protective Measures would include:
Soil conservation and afforestation in river catchments
Adopting new cropping pattern to avoid crop loss
