Besides, the monetary worth of the damage caused to the embankments (other than the breaches) and other flood control structures and recoupment of the damage to bank stabilization works, etc., during this wave of flood has been found to be Rs 1,672 crore. Thus, the monetary worth of the total loss to the WRD infrastructure during this wave has come out to be Rs 1,797 crore, official sources said.
During the second wave of flood, six breaches occurred in the WRD embankments. The monetary worth of these breaches has been found to be Rs 135.22 crore. The monetary worth of the flood-induced damages to the embankments (besides the breaches) and other flood control structures and recoupment of damages to bank stabilization works, etc., has been found to be Rs 1,067.05 crore.

The total length of the embankments in the State is 4,474.42 km. The length of the embankments on the banks of the Brahmaputra is 1,023.89 km. The combined length of the embankments on the banks of the Barak and the tributaries of the Brahmaputra and the Barak is 3,450.53 km.
A survey conducted to assess the present status of the WRD embankments found that of the total length of 4,474.42 km of these embankments, 21.30 per cent is very sensitive, while 53.60 per cent of this length is sensitive and only 25 per cent of this length is relatively in a safer state.

Besides the embankments, the WRD has so far implemented 958 anti-erosion schemes, installed 98 main sluices and 545 minor sluices, among others, sources said.
