Coastal Modeling at Sand Motor by Applying D-Flow Flexible Mesh
Background
Sand Motor
The sand motor is an artificial peninsula on the coast of Ter Heijde, which is a pilot project of coastal protection. The hook-shaped peninsula was completed by mega-nourishment of approximately 20 million cubic meters on the coast between Hook of Holland and Scheveningen in November 2011, with an extension of 1km into the sea and a width of 2km where it joins the shore.
D-Flow Flexible Mesh
D-Flow FM (D-Flow Flexible Mesh) is an unstructured version of Delft3D which is under development at Deltares. It supports unstructured grids and adds a lot of modeling flexibility for integrated modeling of coast, estuary and river. The unstructured grids can consist of triangles, pentagons and 1D channel networks, all in one mesh, which can be applied in a more flexible and easier way. This makes progress since Delft3D usually applies the familiar curvilinear mesh, of which it is not easy to cope with its drawbacks. Also, current software usually combines 1D-2D and 2D-3D in the specific cases. The development will result in easier 1D-2D-3D model coupling and high performance by smart use of multi-core architectures.
Objectives
The basic idea of my traineeship is to set-up a hydrodynamic model for the sand motor using D-Flow Flexible Mesh. Then comparisons are made between modeled results and measurements to validate the feasibility of the project.
