The concept of flooding has a multi-disciplinary definition based on the interest of the defining discipline. However, flood is generally taken to include 'any case where land not normally covered by water becomes covered by water' (FWMA, 2010: Pt 1). In recent decades there have been raging scientific and media debates on likely changes in flood regimes generated by land-use changes and climate change (Ranzi et al, 2002). The crux of most of these debates is centred on the simulated risk from such flood events. These risks are related to human health, infrastructure, socio-economic well-being of affected individuals and damage also to archaeological relics. Methods of evaluating and assessing flood risk have been developed in the field of insurance, technological and environmental fields (Molak, 1997; Jones, 2001). Although river flooding is often related to natural disasters, the impacts of human activities such as urbanization have been observed by many scholars (Sala and Inbar, 1992; Kang et al, 1998; Ranzi et al, 2002). Flood risk is expressed in terms of the probability of occurrence of adverse effects of flood related hazards and vulnerability with potential consequences (Mileti, 1999; Merz, et al, 2007; FWMA, 2010). Although a number of approaches have been tested for flood events prediction, hydraulic models have been specifically designed to predict flood inundation (Horritt and Bates, 2002). Consequently, in the development of an effective and efficient flood risk management strategy hydraulic, hydrologic and socio-economic factors must be taken into consideration (Merz et al, 2007).
