This interdisciplinary study analyses the possibilities of improvements in dredging schemes in the Estuary of the Scheldt. Thereby the newly proposed dredging method of flexible dredging is compared to the conventional dredging which has been applied the past decades. In this comparison the alterations in influences on morphodynamics, ecosystem health and the feasibility are taken into account. Flexible dredging is in its experimental phase, only predictions of morphodynamic effects have small uncertainty; they show positive results on the morphodynamic stabillty in the estuary. Though when these improvements are translated to ecosystem health and feasibility, a positive outcome and very little influence may be expected respectively. Therefore flexible dredging seems to be a promising method for reducing the negative effects of dredging, but needs more thorough investigation, especially to be able to accurately assess long term ecological effects and its costs and benefits.
