Overview of the hydromorphology of ebb-tidal deltas of the trilateral Wadden Sea

Crease in storm-surges may lead to strong erosion. It is concluded that especially the (sub-) inlets with smaller ebb-tidal deltas may respond relatively fast (within a decade or so) and relatively strong to accelerated sea-level rise and changes in storm surges.
A joint trilateral approach to data analysis and research to gain more insight in the possible consequences of (rapid) changes of ebb-tidal deltas and to develop inventories of management options is recommended. The aim should be to develop a system understanding which allows predicting inlet system development over the course of decades. It is also recommended to study the relations between the development of the ebb-tidal deltas with geology, internal and external drivers over decades to centuries.
