Assessment of the probability distribution of the phreatic surface in a regional flood defence: Finite element computation for a better understanding of the influence of precipitation on the phreatic surface

A large part of the Netherlands consists of polder area. Therefore the inhabitants have to rely on the Dutch flood defence system to protect them against floods. A vast network of drainage canals ensures that the seepage water and the precipitation water is transported from the polders toward the outside water. There are several mechanisms which...

Analysis of Model Performance Related to Uncertainty in the Model BEACHPLAN for the Simulation of Shoreline Evolution

As a useful tool in understanding the coastal behaviours, one-line models , which are designed to simulate the long-term shoreline evolution in response to imposed wave conditions, coastal structures, and other engineering activities such as beach nourishment, have been developed and applied to a wide range of projects in coastal engineering and...

Adaptation of the Hollandsche IJssel storm surge barrier

The storm surge barrier and levees located in the Hollandsche IJssel do not fulfill the current safety standards according to the third nationwide safety assessment. The non-closure probability of the storm surge barrier is too high and the inner slope stability of the levees is too low. Besides the problems regarding the flooding safety also...
