Impact of Floods
Floods are natural hazards which are not, in and of themselves, disasters, but they could transform a vulnerable situation into a disaster. The vulnerability of a human settlement is determined through its exposure to flooding. The basic effects are power failure, electrocution and short circuit because of water logging in flooded areas as well as around the substation grids. In Table, we summaries the impact of natural calamities on power utilities.
