About the archive

In 2012 we lost Jean Jacques Peters, former engineer of Flanders Hydraulics Research (1964 till 1979) and international expert in sediment transport, river hydraulics and morphology. As a tribute to him we have created potamology, a virtual memorial archive whose aim is to preserve and disseminate his way of thinking and his morphological approach to river problems all over the world.
This archive provides four modules, each with its specific information set relevant to Peters’ work. Where available and if not confidential, there will also be access to the full text. In dialogue with Peters’ family we continue to make his life’s work accessible.

Abstract
    In 1999, Flanders and The Netherlands agreed to set up a common strategy for managing the Scheldt river in its estuarine reach. In 2002, both parties signed a memorandum of understanding in which was defined a "Long Term Vision" strategy and its objectives. One of these is the preservation in the Western Scheldt of a dynamic and complex flood and ebb channel network Scheldt, the so-called "multi-channel system". The present trend, a continuation of past natural morphological evolutions combined with human interference (poldering, dredging and other river works) may jeopardise this objective.

    An expert team appointed by the Port of Antwerp proposed the idea of morphological dredging for curbing this negative trend, aiming at steering the estuarine morphology. In a first phase, sediment from dredging works could be used to reshape sandbars where needed. One case study is discussed in this paper, the aim being to reconstruct the eroded tip of a sandbar at a bifurcation so that the flood and ebb flows would be persevered, a condition to maintain the multi-channel system in the reach. The strategy would not only cut back on the ongoing degradation of the ecological and morphological values of the estuary, but it would could also possibly help reducing the quantity of material to be dredged on the crossings by increasing the scouring or self-dredging capacity of the flow. A diffuser-type device will be used to disperse the dredged material in a controlled way in shallow water along the sandbar edges.

    Since 2002, the new dumping strategy is being investigated as a pilot project (Plaat van Walsoorden). The research programme combines three tools: field measurements, physical scale models and 3D numerical models. The results of the research work completed so far confirm the feasibility of the idea. Further research work will be needed to investigate the use of morphological dredging on other locations of the Western Scheldt estuary.
