    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.

    This page contains descriptions of best practices or comparisons of modelling approaches from earlier projects, which may help to choose a modelling approach.

    Modelling tidal dynamics in mangroves (by Erik Horstman, Twente University) contains a comparison between 3D (DPM) and 2DH (DPM, Baptist, Manning and non-vegetated) modelling of velocities, bed shear stress and sediment concentrations.
