Abstract
Delta flume experiments are essential to confirm the safety of a dike. Building the design of the dike and making changes to it can be a slow and expensive process. The aim of this study was to investigate whether CFD can be used to assess how safe a structure is. This was done by comparing overtopping data of both CFD and delta flume experiments. From the mathematical notions on waves, structures and CFD, models have been setup in the software waves2Foam. Data of delta flume experiments were then used to validate and calibrate the models. However, focusing purely on the overtopping, results showed that CFD continuously produced a larger overtopping level than the physical experiments. The data displayed a development of high asymmetric waves in the CFD simulations which were assumed to be the main contributor to the high overtopping values. Although attempts for solving this problem failed, CFD did manage to show that some interesting conclusions and lessons were taken out of this research. Scaling and grid sizes did not result in different overtopping results and it showed that CFD was often in line with the reality regarding changes to waves and designs of structures.
