Symposium 2017

Inland Flood Protection in the Netherlands

Facing challenges of tomorrow

On Thursday, the 8th of June, the Hydraulic Engineering student association “Het Waterbouwdispuut” will host the annual symposium. This year we will focus on the inland flood protection in our country. We will look back, but more importantly, we will focus on the decades ahead of us and the challenges that these will offer. For example, very recently a new standard has been introduced for testing the safety of our flood protection system in the Netherlands. What are the consequences of such measures and how can a future engineer deal with the design restrictions in an ever changing society.

The Hydraulic Engineering symposium will take place on Thursday the 8th of June at the Sports & Culture Centre TU Delft. The programme starts at 12:30 and consists of outstanding keynote speeches and pitches from different disciplines, companies and universities sharing their view and experience on the covered topic of inland flood protection and the key challenges we are facing in the future. The day will include lunch, a short coffee break and the event will end with informal drinks.

This symposium is a unique opportunity to discuss all the relevant subjects, linked to this theme and moreover, it provides an excellent networking opportunity, therefore we hope to welcome you in large numbers!

Waterbouwdag 2016

Last Thursday, we were present at the Nationale Waterbouwdag 2016 in Rotterdam. As the board of the Hydraulic Engineering Student Association we were there to assist the organisation and also to represent de students of the MSc. Hydraulic Engineering. We attended some short lectures about all sorts of interesting subjects regarding the present world of hydraulic engineering. Overall the Waterbouwdag 2016 was good fun!

Lunch Lecture Royal Haskoning

Dear students,

A quick reminder that we’ve invited two engineers from Royal HaskonigDHV to come give a lunch lecture this afternoon, at 12:30 in lecture hall D!

The focus will be on dredging works conducted in the inland waterways surrounding the Port of Rotterdam and the creation of the Deira Islands in Dubai. As usual, lunch will be provided for all participants.

See you there!

MSc. Community

The MSc. Community was a great succes! We had a very diverse turnout of students and some very interesting speakers. The event was hosted at the PSOR Cafe where drinks and snacks were served. The event’s main focus, is to inform students about all the possibilities of the MSc. Hydraulic Engineering. Internships, graduation projects, multidisciplinary projects and also all the different possibilities for when you finally have your degree.

 

First we had a short speech from the guys of the International Research Project Delft. IRP is a foundation that provides students with a challenging international and educational experience. Every year a team of 20 master students from the Delft University of Technology will shortlist 5 multinationals each offering an innovative and challenging business project in emerging markets around the world. Over the summer holiday five IRP teams, consisting of four students each, will execute the research project.This year’s location will be Colombia!

 

Niels Drouen discussed his internship he did last summer in Panama for Boskalis. The story he told was very entertaining and made us all enthusiastic about the possibilities internships abroad bring you. The project where Niels was involved, is called the Punta Pacifica, a man-made island just off the coast of Panama City. Niels was involved in all sorts of processes, from planning the construction works to operating a real dredging vessel!

 

Finally we had two guests, Ilse van den Bosch and Bas Reijmerink, from Young PIANC, introducing us to their organisation. Young PIANC is dedicated to the career development of PIANC members 40 years of age and younger locally, nationally and globally. Opportunities in PIANC for Young Professionals include networking through meetings and events, experience on technical working groups, and education with scholarship opportunities. In their own words: “Young PIANC, is similar to the Waterbouwdispuut, only that it’s members are a tad bit older than you guys and already have their degree.”

 

We want to thanks everybody who participated and off course our guest speakers: Niels Drouen, Koen Hiemstra, Ilse van den Bosch and Bas Reijmerink. And finally, a special thanks to our host for the event: Stefan Aarninkhof, thanks for helping us out and navigating us through the event with great enthusiasm!

 

For the students who couldn’t attend this MSc. Community, later this year we will host a second one, but for now you can enjoy the photos!

 

See you at the next MSc. Community!

Thixotropy of fluid mud in ports and waterways – MSc Final Thesis March 2017

Background

The navigation in ports and waterways has to be safeguarded by maintenance dredging, removing sediments deposited by tide, river flow and waves. These deposits consist of soft, fluid-like sediments, referred to as fluid mud characterized by low density and weak shear strengths. As dredging of fluid mud is highly in-efficient, port authorities seek for conditions at which ships can sail through fluid mud, leaving the deposited sediments in place. Thus a new definition of “nautical bottom” within the fluid mud layer has to be considered globally. Due to practical reasons, the density of the fluid mud has been used as a key parameter to define the nautical bottom. However, it has long been recognized that a practical definition of nautical bottom should be based on considerations not only of density, but should also include the viscosity and yield stresses of the mud (the so-called rheological properties of the sediment-fluid mixture. Moreover, it has been found that rheological properties depend on the stress history. This feature of mud is known as thixotropy. To get better understanding of the rheological behavior of fluid mud a new insight into the subject can be obtained from the rheological analysis of mud samples from different ports, i.e. the Port of Rotterdam, the Port of Delfzijl, the Port of Emden, the Port of IJmuiden and the Port of Zeebrugge. The yield stress, dynamic viscosity and thixotropy of mud, rheological experiments can be experimentally captured in the laboratory. The thixotropy of cohesive sediments can be predicted by various rheological models. These models can be utilized to bridge the maritime activities (such as navigation and dredging) to the alterations of rheological properties of fluid mud in different ports and waterways.

Objectives

The first goal of this project is to obtain a new practical under-
standing of fluid mud thixotropy taking into account the physical parameters that might influence the rheological properties of the fluid mud layer. The rheological parameters should be linked to the properties of mud and, as representation for the shear history, to the maritime activities.

Supervisors: Alex Kirichek (TU Delft),

Claire Chassagne (TU Delft),

Tiedo Vellinga (TU Delft/Port of Rotterdam),

Arie Noordijk (Port of Rotterdam)

The second goal of this work is to conduct a laboratory analysis of the rheological properties of mud samples from different ports in order and to explain the differences in rheological behaviour of mud types. The following research questions can be covered during the project:

• What is the impact of navigation and dredging activities on rheological properties of fluid mud?

• How the thixotropy of fluid mud can be linked to the ship navigation and dredging?

• What models are suitable for predicting the rheological properties of mud?

• What is the difference between mud types from different ports in terms of rheological signature?

This project is fully sponsored by the Port of Rotterdam.  The student is expected to start working on this project on the 6th of March 2017. The deadline for applications is the 4th of December.
