- Uncertainty in long-term bio-geomorphological dynamics for vegetated foreshores.
- Vegetated foreshores live, i.e. their formation is controlled by vegetation dynamics and physical forces which significantly interact on a dynamic scale. This interdisciplinary field is labelled bio-geomorphology. Insight in the physical mechanisms behind landscape formation by bio-geomorphological interactions has substantially grown in the last decade. Nevertheless, the
- uncertainty in long-term (order of decades) dynamics of vegetated foreshores is not known so that
- reliable estimates of the contribution to safety of vegetated foreshores are impossible. Moreover,
- the opportunities to actively influence the long-term morphological development of vegetated foreshores via maintenance (e.g. grazing and cutting) are unknown, hampering application.
- In this sub-project of the BE SAFE programme (Building with Nature; BwN) we aim to quantify the uncertainty in morphological development for vegetated foreshores in a probabilistic way. We do this by explicitly accounting for the impact of four contrasting types of vegetation on both hydrodynamics and sediment dynamics. To set up the model we combine flume studies and field experiments executed in close collaboration with other sub-projects within the programme.
