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 |
The hydrodynamic simulations on which the mud transport model is based show realistic values for water levels, salinities and residual currents in the major part of the model domain. However, the propagation of the tidal wave is modelled less accurately upstream of Antwerp. Regarding the mud transport simulations, which are based on simple process formulations, it is shown that a satisfactory agreement is obtained between computed and observed concentration levels and their spatial and temporal variations. SPM levels in the Scheldt appear to be rather sensitive to the volume of harbour siltation and dumping, notably near Antwerp. The sediment budget computed by the model includes an unrealistically high residual sediment flux towards the North Sea. By enhancing the estuarine mud circulation, the modelled residual flux becomes smaller and agrees better with observation-based estimates. A longer hydrodynamic simulation period (presently up to 3 months) would help to analyse the sediment budget and seasonal dynamics in more detail. |
