Internship Coastalfoam

**Internship CoastalFOAM**:
Our team is capable of simulating these physical model tests in two dimensions (2D) and is currently expanding its capabilities to include three-dimensional (3D) simulations. Preliminary findings indicate that 3D simulations provide a more nuanced analysis, particularly in the context of wave overtopping phenomena. This observation prompts the need to quantify the additional benefits that a 3D CoastalFOAM model can offer over its 2D counterpart, including enhanced dissipation and more complex three-dimensional interactions.

The Resilience and Maritime department is seeking a motivated MSc-thesis student with a strong interest in numerical modelling. The objective of this research assignment is to conduct a comparative analysis of small-scale physical model tests and CFD simulations using CoastalFOAM. The focus will be on evaluating the differences between 2D and 3D simulation results. An existing CFD model is ready to assist you in the first steps.

Even though every thesis is unique, there are multiple reference theses available:

- An efficient numerical approach to model wave overtopping of rubble mound breakwaters, Marco Moretto 2020, Delft University of Technology
- Hydrodynamic modelling of wave overtopping over a block-covered dike, Luc Barendse 2021, University of Twente
- Numerical estimation of wave loads on crest walls on top of rubble mound breakwaters using OpenFOAM, Marisol Irias Mata, 2021 Delft University of Technology
- Numerical estimation of upward pressure differences over a placed block revetment under wave loading on a dike, Martijn van Heest, 2023 Delft University of Technology

**What you do as graduate intern**:
We are looking for a motivated graduate student with an interest in hydraulic engineering and numerical modelling. The assignment is to evaluate the differences in 2D and 3D numerical CoastalFOAM modelling on for example wave overtopping or energy dissipation. The numerical simulations are to be compared to the results of laboratory experiments. The measurement data is available for this study.

The aspects of interest are:

- Wave pattern analysis
- 3D energy dissipation
- Overtopping phenomena
- Creation of a comparative video to showcase the outcomes of CoastalFOAM simulations relative to small-scale physical tests

**What you bring as an Intern**:
**Requirements**:

- A MSc student, having a technical background. For example: Hydraulic Engineering specialization (e.g. Coastal Engineering) or Physics
- Interested in numerical modelling
- Experience with Matlab and/or Python
- Loves a challenge and does not get frustrated when things do not work the first time
- Likes to be part of a team and prefers the office environment above working from home
- Interested in joining social activities besides the thesis work as well

**Where you will work**:
Royal HaskoningDHV is a worldwide independent engineering, project management and consultancy firm which integrates 140 years of engineering expertise with digital technologies and software solutions. Our 6,000 colleagues are working from offices in more than 25 countries across the world. Through our mission Enhancing Society Together, we take responsibility for having a positive impact on the world.

You will become part of the Advisory Group Resilience & Maritime the Netherlands. This team
consists of around 180 colleagues and is based in the Netherlands across three offices
(Rotterdam, Amersfoort and Nijmegen). As a team we excel in a wide variety of services and
skills in the fields of Climate Resilience and Maritime developments. We provide our clients,
both private and (semi)governmental, with a range of services throughout the various phases of
a project: from inception, through master planning, feasibility, design all the way to construction
supervision. We have a strong foothold in the Netherlands but we operate worldwide.
