Toelichting (Engels) The Rhine River is considered the backbone of the Northwest European waterways network. Due to the morphological behaviour of the river, navigation is subject to hindrance in some locations and frequent maintenance is being carried out. It is of a primary interest for the river manager to be able to evaluate different maintenance strategies to ensure a sustainable navigation channel. Accordingly, a detailed quasi 3-dimensional morphological model that covers the Rhine branches in the Netherlands was created. In this paper some innovative techniques are presented which have been recently developed to undertake this task, e.g. domain decomposition, simulation management tool, and a novel dredging and dumping functionality. Domain decompostion is a technique in which a model domain is subdivided into several smaller model domains. Computations can be carried out separately on these domains. The simulation management tool allows for efficiently carrying out long-term computation with variable discharge; it helps reduce the computational time significantly. Dredging and dumping operations that allow carrying out actual river maintenance strategy. A case study that evaluates the effect of enlarging the navigation channel on the yearly dredging volume by applying a simple dredging scenario in the Waal River is briefly presented
