The economic risk for inland water transport due to uncertainty in morphodynamic behaviour

River systems are vastly changing environments, not only due to natural process, but also human intervention plays an important role. With the many different river functions at play, large amounts of maintenance budgets are associated with river management. For decision makers it is important to know expected costs or losses and the spread...

In November 2003 Royal Haskoning has constructed a beach nourishment of 1,000,000 m3 as an erosion buffer with a lifetime of 10 to 15 years....

Behaviour of nourishments in quasi 3-dimensional graded sediment models

Bed degradation in a number of Dutch river branches, like the Bovenrijn, can cause various problems in the near future. At low waters the navigation depth at the non-erodible layer near Emmerich can become too small. Other problems could be lower ground water levels and stability of structures in and near the river, like groynes. To diminish...
