Review on the Bed Scouring in the Constriction Zone of Local River Widenings

Giovanni De Cesare, Romain Nathan Hippolyte Merlin Van Mol

Local river widenings serve as a technique for restoring channelized rivers and mitigating river incision. The zone downstream where the widened reach transitions into the channelized river is referred to as the constriction zone. While numerous authors ha ...

Effects of flow guide walls on sediment flushing in peaking hydropower reservoirs

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Romain Nathan Hippolyte Merlin Van Mol

Reservoir sedimentation is known to be a key issue worldwide. One operational measure to deal with sediment accumulations is flushing; however, efficiency is often lacking. The goal of this study is thus to improve the effectiveness and efficiency of flush ...

Morphological processes and potential for lacustrine delta restoration

Giovanni De Cesare, Stéphanie Joëlle André, Alexandre Philippe Louis Antoine Fourrier

Most lacustrine deltas are nowadays highly anthropized systems. River training works during past centuries considered rivers mainly as vectors of water and sediments from a point source to a sink. However, numerous problems have been identified by resident ...
