Introduction
I work part-time as a post-doc at the Technical University of Delft and as a consultant/developer at Nelen & Schuurmans. The combination of jobs offers a perfect balance between research and application. I focus in both jobs at improving and optimizing numerical methods for the computation of hydrodynamics and morphodynamics. After several years of experience we believe that the possibilities of introducing high resolution information about the bed and the roughness improves, the accuracy and the efficiency of these type of simulation. However, we think we can take this to a next level. This is what we would like to see in the near future. I work with several research hydrodynamic codes, to experiment at a small scale and with the subgrid-based hydrodyanamic model 3Di.

Article
To improve the accuracy and the efficiency of morphodynamic simulations, we present a subgrid based approach for a morphodynamic model. This approach is well suited for areas characterized by sub-critical flow, like in estuaries, coastal areas and in low land rivers. This new method uses a different grid resolution to compute the hydrodynamics and...
Article
[1] This study presents a finite volume hydrodynamic model for shallow water flow that computes on a coarse grid, but accounts for high-resolution bathymetry and roughness variations on a subgrid. The detailed information can be incorporated by using the assumption of a uniform flow direction and a uniform friction slope within a part of a coarse-g...
Article
The evolution of the cross-sectional areas of tidal inlets draining the same back barrier lagoon is investigated with a simple model. The main new aspect is that hypsometry (cross-sectional area of the inlet and the wetted surface of the lagoon vary during the tidal cycle) is taken into account to determine the morphodynamic stability of the inlets...

Within this project we have the opportunity to work together with a range experts, ranging from ecologist, biologists, engineers, and physicists, to investigate the small scale and the large scale processes and the relation between the scales within Deltas. It allows us to investigate the wide of range of processes and their importance to the dynamics within the delta. Deltas are generally, throughout the world, areas that are highly populated and are the sole habitats for various flora and fauna. Moreover, they play a significant role in our food production and navigational routes. However, these areas are under the influence of climate change and the impact of human intervention. When we want to protect and preserve these areas we need to understand the processes within such areas. In this context , I'm working on improving the hydrodynamic and morphodynamic computations to support long term simulations for forcasting the evolution of such a delta system. We believe, we need to take small scale processes into account for accurate computations on the large scale. Therefore, we are investigating the further possibilities of the subgrid method.
