Modelling the anisotropy of turbulence with the SWASH model: Heterogeneous roughness conditions in open channel flows

In this study the focus is on modelling turbulence anisotropy in open channel flows with the SWASH model. Turbulence anisotropy significantly influences the flow features of: channel flows with heterogeneous roughness conditions, curved open channel flows, compound channel flows with different floodplain depths, etc. The SWASH model is a non...

Turbulence in shallow jet flows

The general flow pattern of an open channel flow, downstream of a width restriction by two artificial dams, is analysed. A physical Froude-scaled model, under hydraulic rough conditions, with a significant large Reynolds number is used to ensure turbulent flow. Upstream of the dams the flow is uniform in transverse direction, in between and...

Getijberekeningen voor de Oosterschelde

De laatste jaren is er veel belangstelling geweest voor de Oosterschelde. De voornaarnste oorzaak hiervan was wel de dreigende afsluiting van dit bekken van de zee, zoals dit in de Deltawet was vastgelegd. Nu echter na een lange periode van herbezinning en besluitvorming vast is komen te staan dat de Oosterschelde niet zal worden afgesloten,...
