Background

A significant proportion of the coastline all over the word is protected from flooding by Seawalls. One of the primary objectives of the coastal engineering designers is to limit the quantity of wave overtopping to acceptable levels. No safe guidance is yet available to link the severity of peak overtopping flows and velocities to particular wave or structure characteristics. This research focuses on the numerical simulation of the phenomena of wave overtopping which represents one of the most important hydraulic responses of the marine structures. New formulae consider the case of small freeboard, attack wave angle, and new turbulence model for wave breaking will be studied. The evaluation of these new formulae will be checked using Laboratory data.

Aims

  • Simulate the case of small freeboard with the 2-D numerical model. Adding different shapes of an internal obstacle in the domain of study in order to get a new design formula considers this case. The work might extend to study of including a turbulence model to account for wave breaking.
  • Introduce the effect of wave angle on overtopping when it attacks the seawall or the breakwater, which will be studied using the 3-D numerical wave model.
  • Evaluate the results of the 2-d and 3-d Numerical models by making a comparison between the project data and the collection laboratory and field data to give a clear view about the accuracy of numerical models developed and use in the project
