In the past years, it has become increasingly clear that a huge amount of plastic end up in the ocean. Since part of the plastic waste is bouyant, it can accumulate in regions where the ocean currents converge. Several researchers how now reported visual confirmation of this "plastic soup" in these gyres. Over time the large pieces of plastic disintegrate under the influence of sun-light and waves. Smaller particles can be mistaken for food by animals, creating a growing concern for the ecological impact.

Within this project we aim to set-up an initlal model that can represent the transport of plastic on a global scale. We try to focus on the most important aspects for this application and will not try to recreate a global general ocean circulation model. Instead, we will use an existing global ocean model from MyOcean to force the density in the model and keep the hydrodynamics comparatively simple.

The aim of this cooperation is to apply our Delft3D-FM global tide and surge model to study the effects of climate change on the threat of

flooding by coastal high-water. We will run the model for a period of several decades to compute and validate the exceedance probabilities

for high-water with the present climate. Next we will study the impacts of sea-level rise and changes to the storm climate as computed by

climate models.

An important effect for tides on a global scale is the change in the gravity field of our planet by the tidal movement of the oceans. It has been estimated that

this effect is of the order of 10% of the pressure gradient. The SAL term is not present in Delft3D-FM yet and the aim of this study is to prepare for its implementation.
