This literature review is a deliverable within the study "slibbalans Zeeschelde" (WL Project 00_029), and gives an overview of available knowledge on mud transport and stock in the Scheldt estuary. It is meant to be used as a reference and an inventarisation of available knowledge on the mud balance of the Scheldt estuary. Sometimes a claim by an author may have come at odds with more recent insights in system behaviour. The authors have tried to indicate that in the text. Because insights are constantly evolving, this document should be a living document. First, available methodologies to estimate mud transport are presented. Anthropogenic activities in the Scheldt estuary that had a possible impact on the mud dynamics are listed. The main part of this literature review consists of a summary of the most important conclusions of literature describing the mud stock in the Scheldt estuary since 1964 and an overview of historic estimations of mud transport and sedimentation over time in different parts of the estuary. For the sake of consistency, mud quantities are converted to Ton Dry Matter whenever possible (TDM in English, Ton Droge Stof or TDS in Dutch), which correspond to the mass of the grains of sediment in the water-sediment mixture.
