Abstract

Abstract: This paper intends to establish conceptual foundations on the identification of standards and metrics for assessing the impact of hydrological hazards. The economic evaluation of flood damage cost model (EFDC-Model) attempts to estimate the impact of water occurrence, movement, and distribution on GNP growth. The model is based on seven basic indicators: (i) the national precipitation growth rate (∆Pi ); (ii) the main factors which generate large precipitation (∆Li ); (iii) the sinking magnitudes levels rate (ST ); (iv) the national floods recurrence rate (FT ); (v) the floods devastation rate (Dk ); (vi) the economic desgrowth from floods devastation rate (-δf ); and (vii) the floods damage surface. The model investigates the recent floods in the Malaysian states of Kelantan and Terengganu for the period 2014–2015. Highlights: The paradigm of Malaysia hydrological hazards illustrates the level of physical, economic, and environmental vulnerability of the affected areas. The spatial heterogeneity and complexity in flood dynamics are systemic in the sense that the disaster impact is far from linear. The discrepancies of a hydrological hazard assessment are rather a result of the multi‐dimensionality in disaster impact, including the economic situation prevailing in the country before the event and severity of the disaster's consequences and the indebtedness level before the disaster and so on.
