Cost optimal river dike design using probabilistic methods

This research focuses on the optimization of river dikes using probabilistic methods. Its aim is to develop a generic method that automatically estimates the failure probabilities of many river dike cross-sections and gives the one with the least cost, taking into account the boundary conditions and the requirements that are set by the user....

Risk approach to land reclamation: Feasibility of a polder terminal

New ports are mostly constructed on low lying coastal areas or shallow coastal waters. The quay wall and terminal yard are raised to a level well above mean sea level to assure flood safety. The resulting ‘convention-al terminal’ requires large volumes of fill material often dredged from the sea, which is costly. The terminal yard of a ‘polder...

A comparison of a 3 dimensional probabilistic method of berthing structure design and the traditional method of a berthing structure design

Finite element method (FEM) is increasingly applied as a first choice tool for designing structures. The same trend is seen in probabilistic designing. Consequently, the application of the combination of these two methods is discussed in this paper.In this study the presence of potential overcapacity in a structure has been studied. As an...

Risk based design of land reclamation and the feasibility of the polder terminal

New ports are mostly constructed on low lying coastal areas or in shallow coastal waters. The quay wall and terminal yard are raised to a level well above mean sea level to assure flood safety. The resulting ‘conventional terminal’ requires large volumes of good quality fill material often dredged from the sea, which is costly. The alternative...

Reliability-based analysis of river dikes during flood waves

Reliability and risk analyses are basic approaches, nowadays, for flood risk assessments in European countries such as the Netherlands, German, United Kingdom, etc. The methods also receive a lot of interest in developing countries. By considering uncertainties for both load and strength variables, the probability of failure for each element of...

Risk analysis of coastal flood defences: A Vietnam case

This paper aims at risk analysis and the investigation of safety aspects of coastal flood defences in Vietnam. The sea dike system has been actually designed by a 20 to 25 years return period. From the current situation it seems that the dike system is not sufficient to withstand the actual sea boundary conditions. Accurate safety assessment of...
