Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2002-03-01 Abstract Floods are a continuous threat to a large part of the Socialist Republic of Vietnam. The country has suffered from several flood disasters in the past. A great part of the total length of dykes in Vietnam is located in the north of the country, in the densely populated Red River Delta. Flood protection works in the Red River Delta provide safety for twenty million people and enable vital economic activity. The population, the economic activity and the investments are expected to increase rapidly in the future, which will lead to an even greater flooding risk for the protection areas in the Red River Delta. In order to judge whether a flood protection system satisfies the socio-economic safety requirements, a risk analysis has proven to be an effective method. This study aims to introduce a method for risk assessment of flood protection systems in the Red River Delta. A risk analysis of a flood protection system consists of two important aspects. The first aspect is the calculation of the probability of failure of the system and the second aspect concerns the determination of the damage in the protected area in case the water defence fails. The multiplication of those two values determines the average annual damage or risk. The contribution of all elements of the water defence system and different failure mechanisms to the probability of the event 'flooding' can be calculated. As a result it is possible to analyse the effect of certain improvement measures on the average annual damage.
