A flood is the accumulation of too much water which rises to overflow land which is not normally submerged (Mukhopadhyay, 2010; Ward, 1978). Flooding can comprise overflow of a river as a result of prolonged seasonal rainfall, rainstorm, snowmelt, dam-breaks, accumulation of rainwater in low-lying areas with a high water table, or inadequate storm drainage. Floods could also be caused by intrusion of sea water onto coast lands during cyclonic/tidal surges (Handmer, Penning-Rowsell, & Tapsell, 1999; Stoltman, Lidstone, & DeChano, 2004). The terms used to describe flooding are numerous and may mean different things to different scholars with respect to the context in which they are used (Brooks, 2003; Brooks, Adger, & Kelly, 2005). Social scientists and climate scientists often mean different things when they use the term "vulnerability"; whereas social scientists tend to view vulnerability as representing the set of socioeconomic factors that determine people's ability to cope with stress or change (Allen, 2003), climate scientists often view vulnerability in terms of the likelihood of occurrence and impacts of weather-and climate-related events (
