Dr. Thaiënne van Dijk was internationally and scientifically educated in the area of glacial morphology and sedimentology and conducted field research in - among others - Greenland, Ireland, Canada and Iceland. Key areas of glacial expertise include glaciofluvial sedimentology, glacial geomorphology, surge-type glaciers and glacier outburst floods. She organised an expedition to Iceland for M.Sc. en Ph.D. students of Keele University, UK (KICEX98), was assistant investigator in two Earthwatch projects in Iceland and taught and supervised both practical courses and a student fieldwork in Spain.

In 2002, dr. van Dijk took up her position at the Geological Survey of the Netherlands, TNO (currently: Deltares), where she carries out both applied and scientific research. Her research comprises the Quaternary mapping of the North Sea, the morphodynamics of sea beds and the habitat mapping of sea beds, making use of multi and single beam echo soundings, side scan sonar, seismic data and sediment cores. Field works involve hydrographical surveys and bed sampling in the North Sea. Dr. van Dijk is a guest lecturer at the University of Amsterdam, is currently member of STW-committees, the sub-commission on Marine Geodesy of the Netherlands Committee on Geodesy and takes part in evaluation committees.

Thaiënne van Dijk is a lecturer at the department of Water Engineering and Management at the UT since September 2008 (part-time), where she teaches the M.Sc. course ‘Marine systems’ and supervises M.Sc. and Ph.D. students. Her research interests are the coupling of data analyses and physical modelling in the topics of marine morphodynamics and biogeomorphology, with a special interest in the impact of storms on sea bed morphodynamics.


The aim of this research is to link theoretical modelling to data analyses in the areas of morphodynamics and habitat studies of sea beds. Coupling the modelling to data analyses is essential in the validation and improvement of models and in the explanation of morphologic processes observed at sea beds.

The study of marine morphodynamics is concerned with the natural change in sea bed morphology and herein, we focus on the dynamics of bed forms, such as sand banks, long bed waves and sand waves.

The study of biogeomorphology examines the interrelationships among a-biotic local conditions (morphology, morphodynamics, hydrodynamics, sedimentology at the seabed) and the benthos zoography. Sidescan sonograms, multibeam echo soundings, sediment cores and zoobenthic samples are used to investigate these relationships and to classify sea beds.

The impact of storms will form a topic of near future attention, for which new data collection is planned in co-operation with the Netherlands Hydrographic Office. The aim will be to explain the magnitude and frequency effect of storms on sea beds.

This research is being carried out in a dual affiliation to Deltares and the University of Twente.
