Over het archief
In 2012 verloren we Jean Jacques Peters, voormalig ingenieur van het Waterbouwkundig Laboratorium (1964 tot 1979) en internationaal expert in sedimenttransport, rivierhydraulica en -morfologie. Als eerbetoon aan hem hebben we potamology (http://www.potamology.com/) gecreëerd, een virtueel gedenkarchief dat als doel heeft om zijn manier van denken en morfologische aanpak van rivierproblemen in de wereld in stand te houden en te verspreiden.
Het merendeel van z’n werk hebben we toegankelijk gemaakt via onderstaande zoekinterface.

| Abstract |
Furthermore, efforts have been taken in improving the Bijker sediment transport formula used in the model. It was observed than when the model was used for some extreme sea level rise scenarios some unexpected strong cross-shore transport occurred, nevertheless cross-shore processes are not included in the model yet. Based on an extensive set of model tests, two modification of the formulations showed some major improvements of the model behaviour: • Replacement of the default wave-current bed shear stress formula in Bijker’s transport formula with the τcw formula proposed by Soulsby (1995), known as the DATA2 method and based on a fit to laboratory and field measurements • Replacement of the default (fixed) breaking wave parameter (b) in in Bijker’s transport formula with a spatial-temporal varying expression that depends on the wave height and water depth ratio (Bijker, 1971). Two other improvements, but with less impact have been implemented as well: • Use of the formula for deviation (correction of sediment transport direction due to slope effect) by Talmon et al. (1995) instead of the default one (Koch and Flokstra , 1981) • Minimum depth for bed load equal to 0.1 m (instead of 0.01 m) The findings mentioned above were confirmed through a series of applications, which included: (a) the calculation of the annual longshore transport volumes along the Belgian coast and (b) a storm event (Ciara) in February 2020 with important impact at the marina of Blankenberge (c) a long-term morphological hindcasting (years 1986-1996) at the area east of Zeebrugge port related to the extension of the port which was completed in 1986. |
