This study further develops the method of probabilistic design and to address a knowledge gap in its application regarding safety and reliability, risk assessment and risk evaluation to the fields of flood defences. The thesis discusses: - a generic probabilistic design framework for assessing flood defence systems; - statistical techniques in establishing a probabilistic hydraulic boundary conditions regarding to the extreme environmental hydraulic load variables. - safety assessment and reliability based design in answering the questions of e.g how safe is the system; where is the weakest link of the system and how can be improved the safety of the system in order to meet a pre-defined target safety against floods. - risk assessment and evaluation frameworks for low-lying flood prone regions taking into account region/country specific characteristics, such as social economic development, local attitude towards flood risk etc. The proposed approaches can be further developed to apply to various common problems in civil engineering design. Applying these modern approaches in the same fields in developing countries, where the safety of the actual flood defences are relatively low and safety regulations are not well defined, is still limited and therefore promoted. These approaches have been tested for a case study of coastal flood defences in Vietnam. It has been proved that the specific reliability and risk based models developed in this study can be applied adequately to these situations in developing countries. In addition, the models are able to overcome problems of limited data.
