A cost optimal design of a sea dike: Using probabilistic methods and flexibility in the distribution of the total failure probability over the various failure mechanisms

During this research a method is developed for finding the cost optimal design of a sea dike when a probabilistic method is being applied and flexibility is allowed in the distribution of the total failure probability over the various failure mechanisms. A probabilistic model has been set up to calculate the cost optimal design for a sea dike...

Hydrograph shape variability on the river Meuse

Design water levels are a basic concept in flood risk management practice. These water levels with a specified return period are used for the design of dikes and other flood protection measures along the river Meuse. Current practice is that these water levels are determined by hydrodynamic simulation of a standard design hydrograph at the...

Optimization of the operational use of entrance channels based on channel depth requirements

Large capital and maintenance dredging operations are required to ensure the accessibility of many ports. The expenses associated with the dredging operations can have a significant impact on the finances of these ports. Therefore, considerable attention to the design of the width and depth aspects of access channels is justifiable. This study...

Cost optimal river dike design using probabilistic methods

This research follows a fully probabilistic approach in order to estimate the optimal design for a river dike cross-section, taking into account the investment costs. From the theory studied, the failure mechanisms that contribute most to the failure of river dikes are identified. These are overflowing, wave overtopping, piping and inner slope...
