Introduction

More and more, aquatic and semi-terrestrial vegetation (salt marshes, mangroves, floodplain vegetation) is playing a prominent role in interdisciplinary studies of recovering or threatened ecosystems and flood risk reduction. Both within Deltares and in the world around us, vegetation is a topic of interest for many different disciplines (hydrodynamics, morphology, (ground-)water quality, ecology and eco-engineering). Because vegetation modelling is a very interdisciplinary subject, it tends to fall between programmes or themes and people of different organizations may have difficulties to stay aware of the state-of-the-art. This wiki will help the vegetation modelling community (and other modellers) to integrate vegetation modelling tools, share knowledge and keep each other up-to-date on developments.

On this wiki, you will find an overview of presently available vegetation modelling tools and their status as well as planned/suggested developments.
There is a section on recent and ongoing projects in which vegetation modelling tools are used.
There is also a materials section where you can find illustrations and presentations related to general vegetation modelling.
To see who is doing what, there are pages on people involved internally and on co-operation with other institutes and companies.
To keep each other up-to-date, there are sections on activities and ideas for developments, research and market actions.
