Floods are the most frequent type of natural disaster and occur when an overflow of water submerges land due to excessive rain, ruptured dam or rapid melting of snow. Coastal flooding occurs when a large storm or Tsunami causes the sea to surge inland. Floods can cause widespread devastation, resulting in loss of life and damages to property and critical infrastructure. Critical Infrastructures, including energy, transport, digital communications and water, are prone to flood damage. Their geographical extent is a determinant of, and is determined by, patterns of human development, which is often concentrated in floodplains. By using Satellite data and crowd source data the detection of this critical infrastructure damage can carried out for timely decision making by authority.
