Box culvert with suitable dimension to be reconstructed,  the natural flow  path of nala should be channalised and no encrouchment at 10m on both side flanks to be allowed. House on left flank of stream partially damaged (Mr. Bhaskaran, Puvathingal), so
It is a old debris flow path. Reduction of strength on super saturation due to excess pore water pressure is also a cause.
