Modelling

Models aim to describe the natural processes in a simplified way to improve understanding of a system, its drivers and feedbacks. This system can be an entire shelf sea, a tidal inlet or the population of a particular species. Modelled data can augment sparse observations and help create the wider picture, both in space and time.

Ecosystem modelling

Ecosystem modelling

Ecosystem modelling started in the 1980's in the project group BOEDE (Biologisch Onderzoek Eems-Dollard Estuarium).

GETM-ERSEM-BMF model

GETM-ERSEM-BMF model

The basic flow of carbon and nutrients within ERSEM-BFM and the application of the water column model for spatial studies (right).

Integral Projection Model

Integral Projection Model

Life‐cycle diagram of a model system, showing the processes influencing population size with trait distribution (laying date) between times.

End-2-end

Schematic of an end-2-end model consisting of a hydro-biogeochemical model (left) and a (double pathway) size-based model (right).

Larval Transport

Larval Transport

Yearly measurements of arriving juveniles show a strong inter-annual variability. A numerical model is used to study the causes of this variability.

Water column

Spatial modelling with an ecosystem model: from general water column processes to a geographically explicit application.

Sediment

Modelling the transport of suspended sediment in the Wadden Sea to find out wheter the net sediment flux keep up with local sea level rice.

Dynamic Energy Budget

Dynamic Energy Budget

A standard DEB model describes how an organism uses food to live in a changing environment. The energetics of the bivalve A. islandica.
