Internship - Modeling Technical Fish Passages

Arcadis is the global partner at the forefront of the most impactful projects of our time. We help our clients make sustainable choices through the combination of digital innovation, expertise, and future-oriented skills in areas such as environment, energy, water, buildings, transport, and infrastructure. We take that extra step to offer our clients tailored solutions for design, engineering, and consultancy. By utilizing data-driven insights, we shape the natural and built environment together.

With more than 36,000 people, we combine global expertise and tackle challenges such as climate, affordable energy, and livable cities together. We improve the quality of life through our presence in more than thirty countries.

Within the Water Quality and Ecology team, you will work on issues at the intersection of ecology, water management, and hydraulics. In this internship, you will focus primarily on the calculation, analysis, and interpretation of technical fish passages using modeling, preferably with 3D Computational Fluid Dynamics (CFD) such as flow-3D or ANSYS fluent. In doing so, you will investigate how different types of technical fish passages behave hydraulically under varying conditions and to what extent they contribute to making barriers passable for fish.

Think here of analyzing the technical parameters of the passage and the question of how these factors influence different fish species and life stages. You will therefore not only look at whether a fish passage functions, but also why and which design choices are decisive in that regard.

An important part of the internship is testing boundary conditions, assumptions, and design guidelines from literature against model simulations and, where possible, against practical situations. In doing so, you will make a substantive contribution to deepening knowledge about fish migration and to a better understanding of technical fish passages. The results of your work can subsequently be used, for example, to better advise water boards on the design, assessment, and improvement of fish passages.

You will join a close-knit team full of knowledge in the fields of hydrology, ecology, and water quality. We are engaged in a wide range of activities in the areas of water management, water quality analysis, and ecological status assessments.

In your role as intern 'CFD modeller of technical fish passages', you will be guided by a dedicated Arcadis specialist. This mentor will support you with content, share knowledge, and actively collaborate with you on specific parts.

Affinity with Computational Fluid Dynamics (CFD) and (fish) ecology is a plus.

Are you completing a HBO (University of Applied Sciences) or WO (Research University) degree in the field of ecology, water and/or civil engineering, modeling, or CFD, and do you have an affinity with one of these fields? Then you can start working with us on this internship or graduation topic.

• You are available from September for at least 4 months. Preferably 5 months.
• You possess an excellent command of the Dutch language and a good command of the English language, both spoken and written.
• You have an open and eager-to-learn attitude to master new subject matter and to collaborate with specialists or fellow students in this regard.

Desired competencies

• You have access to CFD software such as flow-3D or ANSYS fluent through your studies or institution.
• You have an affinity with CFD and are open to deepening your knowledge of this during your internship.
• Additionally, you can work well independently and have sufficient decisiveness to engage in discussion with experts in the field and to establish contact with clients to obtain background information or data.
• Since our clients work and communicate in Dutch, we expect you to have a good command of the Dutch language, both orally and in writing.
• You have an analytical eye.
• You have a strong affinity with modeling.
• You have an independent and proactive attitude.
• You are entrepreneurial, proactive, flexible, and independent, whereby we expect that you can collaborate well and enjoy contributing to our team.

Why Arcadis: Wherever you work, whatever you do, as an Arcadian you contribute to our mission 'Improving quality of life'. That is what connects and inspires us. At Arcadis, we ensure that everyone gets the opportunity to get the best out of themselves. By creating an environment in which everyone feels at home and is given room for development, we believe that together with you, we can make an impact for the future.

Characteristic of our culture are inclusivity, diversity, and corporate social responsibility. We carry out various activities on these topics. Arcadis offers you the chance to gain practical experience in the form of an internship or graduation assignment. We will determine the content of the assignment together. During your internship, you may organize your work flexibly across different locations and working hours. Additionally, you will get to know colleagues better by participating in activities such as those of the active youth association The Young Part. Many interns/graduates grow into a junior position. Learning at Arcadis also means that you receive an internship allowance.
