In the Water Engineering and Management Department of the Cluster of Civil Engineering a vacancy exists for a PhD student. 
Background: Research of the Water Engineering and Management group aims at developing knowledge of large natural water systems with the goals to develop instruments for the analysis of water management problems and to find solutions for these problems. Recently, a large research grant was awarded for a research project aimed at the improvement of sand transport models, which are to be applied for the management of shallow seas and the coast. More specifically the project focuses on sand that is transported by short waves in the landward or seaward direction (cross-shore transport), a sand transport component which is of  great importance to coastal erosion and  accretion.  This project will involve close collaboration between 3 postdoctoral researchers and a PhD student based at the Universities of Aberdeen, Liverpool and Twente. 
Project description and allocation of tasks: The PhD research will be aimed at the development of a model for sand transport under breaking waves. During the breaking process of waves near the beach large quantities of sand are stirred up from the sea bed and transported. The detailed dynamics of this transport process, which takes place near the sea bed (bed-load) as well as higher in the water column (suspended-load), are still relatively unknown and quantitative transport models for breaking waves are therefore still unreliable.      

The PhD student will approach the research problem by:
-          Acquiring  insight into the dynamics and in the modeling of fluid flow and sand fluxes induced by wave breaking, using existing literature, models and measurements.
-          Conducting laboratory experiments with breaking waves in the large wave channel at the Technical University of Catalonia in Barcelona; in this unique laboratory facility waves and the sand transport process can be simulated close to full scale. For the duration of the project (4 years) three series of experiments are planned, each spanning two months.
-          Contributing to the development of a new sand transport model, that can be implemented in morphological modeling systems for practical problems in the marine coastal environment. All researchers in the project will contribute to this model development, which will be carried out in close collaboration with the involved Dutch and English agencies (the ‘Users’ of the transport model).        
Projectmeetings will be organized two times per year; meeting venues will rotate between Twente, Aberdeen and Barcelona.


We are looking for an enthusiastic PhD student with knowledge of or strong affinity with fluid mechanics and transport processes, experimental research, and coastal sediment dynamics. The candidate should have a Master’s degree in Civil Engineering, (Geo)Physics, Physical Geography or a closely related area. Further, we find it important that the researcher is able to set his or her research in a broader perspective (internationally) and that he or she will be able to coordinate this with the involved parties. Therefore, we are looking for people with an open mind, strong communicative qualities and excellent comprehension of English, both in spoken language and in writing. Comprehension of the Dutch language is beneficial.

Information and applications: For more information about this vacancy you can contact Jan S. Ribberink, telephone             +31 53 489 2767       (email: More information is available (about the Water Engineering and Management Department). The start of the project is planned around February or March 2012. 
Your written application, with a CV, academic record (including a list of courses with marks), the names and addresses of two references and, if applicable, a list of publications should be sent before the 6th of January 2012 through the following  application link.


We offer a position as a PhD student at the University of Twente. The salary for PhD research starts at € 2042,- gross per month for the first year and extends to a maximum of € 2612,- gross per month in the fourth year (in accordance with the Collective Labour Agreement for Dutch Universities).
