Flooding
Flooding is excess flows exceeding the transporting capacity the drainage system, river channel and other water transporting system, where by water inundates outside areas. Climate scientists are typically focused on trends in magnitudes of precipitation and flooding, engineers may be more concerned with changes in the number of execedances (Bonnin et al., 2001). Flooding is a result of heavy extreme events of rainfall, climate changes extreme events and much water in the new place unusual occurrence of water on land overflow in an area impacts on infrastructure. Extreme events induced by global climate change, such as more persistent rainfall leading to flooding or more intense tropical storms, cause threatening risks to transportation …show more content…

The flooding risk probability, hazard of extent, vulnerability of adverse effect and its consequences are a function of hazard, exposure, and vulnerability (IPCC, 2012; UNISDR, 2011). Risk is consequences depend on what is exposed the area to the hazard and how much it is vulnerable to its damage (Fedesk et al., 2007) (UNISDR, 2011). The frequency, magnitude and severity of flooding are increasing in many parts of the world associated with population pressure, urbanization and climate change (Hirabayashi et al., 2013;Jongman et al., 2014). The global population at risk of flooding expected to rise with temperature (Hirabayashi and Kanae, 2009). Flooding is one of the most frequent and destructive environmental hazards that occur annually worldwide (United Nations International strategy for Disaster Reduction (UNISDR, …show more content…

Population socioeconomic development increases factors, such as more development in exposed areas, climate change is expected to exacerbate these impacts (IPCC, 2012, 2014).Climate change and increasing urbanization are both projected to result in an increase in surface water flood events and their associated damages in the future.
Population growth, increases in wealth, and accumulation of assets in areas at risk from natural hazards have been found to be the main underlying reasons up to now for increasing losses from natural disasters (Crompton and McAneney, 2008; Pielke et al., 2008). Under the ongoing socioeconomic change, natural hazard risk is likely to increase independent from climate change (Bouwer et al., 2007; Feyen et al., 2009). In general, losses and damage from natural disasters around the world have been increasing more rapidly than general economic growth, owing to the rapid development of population and assets in large urban areas in at risk areas (Bouwer et al.,
