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...

A stochastic model approach for optimisation of lowland river restoration works

Over the course of centuries, river systems have been heavily trained for the purpose of safe discharge of water, sediment and ice, and improves navigation. Traditionally, dikes are used to be reinforced and heightened to protect countries from ever higher flood levels. Other types of solutions than technical engineering solutions, such as...

Model tests of enlarged navigation channel at Miller Sands bar, Columbia river estuary

The paper describes a series of tests made in the Columbia River Estuary model at the U. S. Army Engineer Waterways Experiment Station concerning enlargement of the navigation channel at Mi ller Sands Bar. Tests were conducted to determine the effects of enlarging the channel and to determine the effectiveness of various combinations of proposed...
