Tóm tắt
The Mekong River Delta is one of the most vulnerable areas in the world. Because of climate change, the risk of road flooding in the Mekong River Delta is increasing. Road flood disaster is considered as a series of damage processes affecting a road under the effect of different factors such as natural and social factors. Thus, index weight evaluation is a critical part in multi-index evaluation as well as road flood risk management. Some main flood-causative factors considered in this paper are road characteristics, climatic factors, hydrological characteristics, geology environmental factors and social factors. The significant criteria of road flood vulnerability are identified. The weight of different criteria was determined using the subjective method based on the Analytic Hierarchy Process (AHP). The obtained weights can be used for the flood risk evaluation and classification, providing valuable information for decision-making process in the road flood management to prevent and decrease the losses of roads during natural disaster like floodingTài liệu tham khảo
