Currently I am working on numerical modeling of aeolian sediment transport.

In the ShoreScape project I supervise Paran Pourteimouri, a PhD candidate who is investigating the influence of buildings on aeolian sediment transport to the dunes using OpenFoam. In many coastal areas buildings are placed on the beach, because people are attracted to the sea. However, these buildings also affect Aeolian sediment transport towards the coastal dunes. The dunes provide protection to the hinterland during storms. Therefore it is important to know what effect buildings have on the sediment supply towards the dunes.

Swash zone processes

In the Shaping the Beach project I supervise Joost Kranenborg, a PhD candidate who is investigating sediment transport in the Swash zone using OpenFoam. The Swash zone is the interface between the wet and dry part of the beach. It is in this zone where sediment transport accretes or erodes a beach and therefore essential in coastal protection.

Modeling storm effects on sand wave dynamics

During my PhD I investigated the effect of wind waves and wind-driven flow on sand wave dynamics. These effects were investigated on both small-amplitude as well as finite-amplitude sand wave dynamics. Particularly wind waves reduce the growth rate (in the small-amplitude regime) and reduce the height of fully grown sand waves. Wind-driven currents cause sand waves to migrate. My PhD research was finalized with the Thesis entitled “Modeling storm effects on sand wave dynamics”, which contains three peer-reviewed journal articles. My PhD was part of the SMARTSEA project, which is partly funded by NWO-TTW.

During my PostDoc within the SMARTSEA project I investigated the effects of dredging on sand wave dynamics. I investigated the response of sand waves to dredging activities.

Tidal sand waves are marine bed forms that are formed by the interaction of tidal currents with the sandy seabed, such as in the North Sea. Their dynamics – causing a constantly changing seabed – are of interest for the safety of various offshore applications and activities. For instance to guarantee safe navigation, positioning and maintaining pipelines and communication and power cables, placement of wind farms, and the burial and exposure of objects on the sea floor such as ammunition and sea mines.
