Assessing Flood Risk
Flooding causes catastrophe all over the world - the July 2010 floods in Pakistan killed more than 1,600 people and since the year 2000 flooding in Europe has caused at least 700 deaths and the displacement of about half a million people. In addition to the human costs; flooding has proved to be the world’s most expensive type of natural disaster – the cost of global flood damage between 1991 and 2005 is estimated at $366 billion. Climate change assessments estimate that the severity of flooding and the costs, both human and financial, are likely to increase - making flood management a pressing concern for the future.
Earth Observation technology can help both immediate and long term flood scenarios. Accurate maps of flooded areas can be produced swiftly allowing relief efforts to concentrate their resources efficiently.
Risk assessments can be made using data gained from remote sensing techniques. Such assessments of risk are useful for the flood mitigation and planning purposes of local authorities, emergency services, local planning authorities and utility companies and provide valuable risk information to the insurance and property industries and the general public.
