“…National and local authorities in sufficiently gauged regions often prepare their own standard methodology for assessing flood risks including damage functions, as in the UK (Penning-Rowsell and Chatterton, 1977), Netherlands (Messner et al, 2007), EU (Meyer et al, 2009), and Japan (Kazama et al, 2009). However, the framework for flood risk assessment in developing countries with typically insufficient hydrometeorological measurements causing relatively low data availability is mostly under development, although many studies have been already conducted (Ganji et al, 2012;Chau et al, 2015;Domeneghetti et al, 2015).…”

Abstract:Flood damage functions form the core of flood risk assessment. This study proposes a method for establishing flood damage functions for agricultural crops in data-scarce regions. The method assumes that the flood damage ratio is a function of inundation depth only and utilizes inundation depth estimated from flood extent information and hydro dynamic simulations. The parameters of the damage functions are calibrated through the SCEUA method (Shuffled Complex Evolution method developed at The University of Arizona) so that the calculated flood damages match observations compiled in flood disaster statistics. The established three functions show good agreement with actual agricultural damages caused by a rainfall event in 2010 and are validated against another rainfall event in 2009. The results indicate that the established damage functions are capable of estimating flood damage at the district scale, while damage estimations at finer spatial resolution differ between the functions, suggesting that detailed statistical data need to be incorporated to reduce the estimation uncertainty at fine scales.

“…Like other countries that are prone to natural disasters, Vietnam has developed extensive legislation in this area that focuses on prevention and mitigation measures ( [13,6]). Despite the willingness and efforts made by the government, including structural measures and policy development, the damage caused by natural disasters remains significant, particularly in the agricultural sector ( [7]). Therefore, it would appear that existing disaster and post-disaster relief policies in Vietnam have a number of limitations.…”

“…The Central region is characterised by a steep and narrow terrain, and fragmented by rivers 20 deriving from westward mountain ranges to the East Sea of Vietnam. Due to such conditions, this region is often exposed to floods and storms causing significant losses in human lives and properties (Shaw, 2006;Tran et al, 2008;Chau et al, 2014a).…”

Abstract. Flood damage data recorded shows that Vietnam is vulnerable to flood hazards. This has severe consequences for the Vietnamese people, especially in terms of an unacceptably high death toll. To an extent, the high level of vulnerability is related to an insufficient capacity to cope with natural hazards, as is common in developing countries. On the other hand, social factors play their part and around the world, certain at-risk groups are systematically marginalised as a matter of policy. The number of fatalities is the most important indicator in flood risk assessment. However, there is a significant lack 10 of systematic research on flood fatalities in Vietnam. We respond to this gap and explore the national disaster database of
