Flood Characteristics and Mitigation Issues
نویسنده
چکیده
Among various natural disasters floods make the largest impact in terms of number of casualties, people affected and property lost. Flood data during the past 30 years show that flood events that cause significant impacts have increased at a steady rate. Available data suggest that this increase could be attributed to increasing population and exposure, increasing property values located in vulnerable areas and migration. For flood disaster mitigation, it is useful to consider the different types of floods, i.e., flash floods, river floods or urban floods and strengthen preparedness through risk assessment and appropriate mitigation measures. Several case studies are described to highlight the flood characteristics and mitigation approaches.
