Experimental Study on Bedload Transport and Bedforms: Behaviour and Interplay in Steep Turbulent Streams
In mountain regions, steep streams play an important role in water and sediment connectivity. In these highly dynamic systems, water flow features, sediment fluxes and stream morphologies are tightly interlinked over a broad range of temporal and spatial s ...
EPFL2022Hydro-mechanical behaviour of a sandy silt from a river embankment
The paper presents the results of an experimental campaign aimed at characterizing the hydro mechanical behaviour of a sandy silt from a river embankment Due to continuous river level fluctuations and changing climatic and environmental conditions, flood e ...
E D P SCIENCES2020Erosion, transport and deposition of a sediment replenishment under flood conditions
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson
River reaches downstream of dams with constant residual discharge often lack sediment supply and periodic high flows due to dam sediment retention and flow regulation, respectively. To test a novel multi-deposit methodology for defining environmental flows ...
2020Sediment replenishment combined with an artificial flood improves river habitats downstream of a dam
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly, Christopher Robinson
River reaches downstream dams where a constant residual flow discharge is imposed, often lack sediment supply and periodic inundation due to the absence of natural flood events. In this study, a two-year return flood was released from an upstream reservoir ...
2019Floating modular unit for controlled sediment flushing regarding sediment size and concentration
Sediment management is a challenging discipline, especially in regions where the storage capacity of reservoirs decreases due to sediment accumulation. This paper shows an innovative and holistic modular technical approach to the problem, considering a gre ...
ed. Hydropower&Dams, Aqua Media International2018To what extend the dam dredging can influence the background level of metals in the Rhine River: using chemical and biological long-term monitoring to answer
Dredging generates remobilisation of sediments contaminated by non-degradable compounds such as metals, to which aquatic organisms can be exposed. This study aims at assessing the environmental impact of sediments remobilised in the Rhine River (France) du ...
Edp Sciences S A2017Properties and pozzolanic reactivity of flash calcined dredging sediments
Ruben Anton Snellings, Pawel Tadeusz Durdzinski
Dredging of ports, harbours and waterways generates vast amounts of sediments that find few applications and need to be disposed of. In the port of Antwerp, Belgium, each year 450,000 t (dry matter) of dredging sediments are mechanically dewatered and stoc ...
Elsevier Science Bv2016Replenishment of sediment downstream of dams
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 ...
