Sediment Evacuation from Reservoirs through Intakes by Jet-Induced Flow

Anton Schleiss, Giovanni De Cesare, Jolanda Maria Isabella Jenzer Althaus

Reservoir sedimentation is considered as a sustainability problem. A concept getting down to the root of the cause was developed and tested in laboratory experiments. The idea is to maintain sediment in suspension, i.e., avoiding its settling near the dam ...

Laboratory research: bed load guidance into sediment bypass tunnel inlet

Anton Schleiss, Giovanni De Cesare, Pedro Filipe De Almeida Manso, Milad Daneshvari

Sediment management in reservoirs situated in mountainous regions is a critical operational concern with direct implications in live storage sustainability and therefore in production revenues. The paper presents the main results of a physical model study ...

Ecomorphodynamic approaches to river anabranching patterns

Paolo Perona, Benoît Crouzy

We investigate the influence of vegetation on river morphological instabilities using an analytical framework. We first discuss the important role of the hydrological (flooding frequency) and biological (vegetation development rate) timescales. As long as ...

Physical modelling of artificial river replenishment techniques to restore morphological conditions downstream of dams

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco

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 ...

Sediment management measures for river restoration and flood protection in alpine valleys

Bastien Roquier

Sediment transport plays a key role in the morphological and ecological value of river ecosystems. The present study explores the design of sediment management measures for a flood control and revitalization project in an alpine valley of the Swiss Alps. T ...

Effect of compressed riprap thickness on the stability of river banks

Anton Schleiss, Michael Pfister, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi

One of the common measures for river bank protection is the installation of riprap. There are several methods to design riprap appropriately, which are however generally limited to dumped medium size blocks. Nevertheless, an additional resistance against e ...

Inter-laboratory trial of a standardized sediment contact test with the aquatic plant Myriophyllum aquaticum (ISO 16191)

A whole-sediment toxicity test with Myriophyllum aquaticum has been developed by the German Federal Institute of Hydrology and standardized within the International Organization for Standardization (ISO; ISO 16191). An international ring-test was performed ...

Flow-induced uprooting of young vegetation on river bedforms

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier

Riparian vegetation stabilizes sediment by its roots and henceforth impacts riparian morphodynamics. After germination or vegetative reproduction on river bars or islands, juvenile plants are exposed to a high risk of mortality due to uprooting by floods. ...
