Dams on rivers alter the sediment continuum, trapping water and sediment in the upstream reservoirs. River reaches downstream are affected by several negative effects, such as bed incision, reduction of the river morphological variability, development of a ...

Dams trap sediment in the upstream reservoir, which may lead to river bed armoring, streambank erosion and failure, channel incision and reduction of the morphological diversity in the downstream river reaches. The replenishment of sediment is a mitigation ...

First applied in the 1980’s, the artificial replenishment of sediments is one technique proposed to solve the problem of sediment deficit downstream dams. The present experimental research aims at improving the technique of river replenishment and at provi ...

The artificial replenishment of sediment is used as a method to re-establish sediment continuity down- stream of a dam. However, the impact of this technique on the hydraulics conditions, and resulting bed morphology, is yet to be understood. Several numer ...

Dams interrupt the longitudinal connectivity of a river as they store water and trap sediment. When transport capacity downstream of dams exceeds sediment supply, water becomes hungry and channel incision, bed armouring and reduction of morphological diver ...

The transport of ballast caused by the overflowing of longitudinal drains is a prime example of the interactions between the railway track and its environment. In such conditions, water flowing from the platform, along with debris, may drag the ballast off ...

Since its inauguration, in 1993, the horizontal weir crest of the Olympic fountain in Lausanne has suffered from differential settlings leading to a difference in level of more than 30 mm. The settling involves a visible non-uniform discharge distribution ...

Dams trap sediments in the upstream reservoir, thus the continuity in sediment transport along the river is interrupted. Several negative aspects related to the lack of sediment supply were observed downstream many dams and the artificial replenishment of ...

Hydraulic scale effects on physical Piano Key weir (PKW) models were so far rarely discussed in literature, even though almost all prototypes are model-tested before construction. In parallel, physical weir models are generally known to include significant ...
