Joost Brinkkemper PhD

Joost holds the position of Specialist Coasts and Seas at WaterProof BV. He graduated in 2013 from the master Physical Geography at Utrecht University with a specialisation in coastal dynamics and fluvial systems. During his graduation research, he focused on wave non-linearity in the shallow coastal zone and during an internship at the LIPC coastal instate in Merida (Mexico) he worked on wave run-up at the local beaches. After his master, Joost continued his career at Utrecht University as a PhD candidate, studying sand transport in the surf zone. He obtained his PhD degree in March 2018. During his time at Utrecht University, he gained much experience in collecting and analysing field data and working with several numerical models.

At WaterProof, Joost is involved in a wide variety of subjects. He works on hydrodynamic and morphodynamic studies in the coastal zone, but he is also heavily involved in projects concerning underwater acoustics. As Joost has experience with both numerical models as with executing field measurements, he is also often involved in field campaigns. Therefore, Joost is at the moment often found at sea for collecting measurements of underwater acoustics, and those measurements are also analysed by himself after returning to shore.

Janneke Krabbendam MSc

Janneke is a PhD candidate at WaterProof BV. and the Institute for Marine and Atmospheric Research (IMAU, Utrecht University). She is supervised by Prof. Dr. Ir. Huib de Swart and Dr. Ir. Abdel Nnafie. Janneke studied Climate Physics at Utrecht University and did her final graduation research (with the same supervisors) also at WaterProof. Her graduation research focused on modelling finite amplitude tidal sand waves using Delft3D. Among other things, this research focused on studying the influence of different environmental parameters on the characteristics of tidal sand waves and the recovery of sand waves after a disruption caused by e.g dredging.

The PhD project is a logical continuation of her graduation research and focuses on developing new, process-based knowledge and methods that will strongly improve assessments of burial depths of cables and pipelines in areas of the North Sea where active tidal sand waves occur. This PhD project is part of the Industrial Doctorates program of NWO (Netherlands Organisation for Scientific Research), in which PhD candidates carry out their research at both a university and a participating company.
