Influence of channel geomorphic units on bedload transport and river morphology during low‐magnitude bed‐forming floods coupled with sediment augmentation

Giovanni De Cesare, Severin Stähly, Christian Mörtl, Robin Schroff

In this study, we map different types of channel geomorphic units in a sediment-starved, residual-flow reach before and after an artificial flood. Bedload particles of a previous sediment augmentation measure are tracked with passive integrated transponder ...

Morphological evolution of the Rhone River in the Martigny bend

Giovanni De Cesare, Azin Amini, Samuel Luke Vorlet, Najla Schaller

Sustainable water management is a principal matter to ensure safety of waterways (Berga, 2016). In this framework, the correction of the Martigny bend is a priority measure of the 3rd Rhone River correction in Switzerland, which aims at increasing the floo ...

Study of Aerodynamic Grain Entrainment in Aeolian Transport

Aeolian transport controls landform formations on Earth and other planets and crucially affects the atmospheric system. With elaborate wind tunnel measurements, we find that the aerodynamic entrainment rate follows a yet unreported exponential increase in ...

Bedload transport: a walk between randomness and determinism. Part 1. The state of the art

Christophe Ancey

This paper outlines the various approaches used to calculate bedload transport. As bedload transport exhibits considerable spatial and temporalvariations, computing the bedload transport rates and morphological changes experienced by streambeds is difficul ...

Electricity generation, water supply, flood protection, flow regulation and navigation are amongst the main services provided by reservoirs. Sedimentation affects the sustainability of reservoirs, by reducing their storage capacity, and increases the negat ...

Sediment traps are crucial elements for flood protection in mountain rivers with high sediment transport capacity. Existing structures often interrupt the channel connectivity. Ideally, a sediment trap should be permeable for bed load during non-hazardous ...

Gravity currents are density-driven flows that are able to transport high amounts of sediment and are responsible of great geomorphic changes. Moreover they can have severe repercussions on the environment since they are conveyors of substances, e.g. pollu ...

Experimental study on bedload transport, fluctuations and coupling with bedforms in steep turbulent streams.

Ivan Pascal

Sediment transport is one of the main morphodynamic processes in mountain streams. Understanding bedload transport is fundamental to prevent and mitigate hydrogeological hazards and for the resources management. The classic bedload discharge predictions ar ...

Remote-sensing and classification of benthic landscapes for satellite derived bathymetry

Selim Amrari

Bathymetry is a crucial variable for many researches, such as monitoring of the coral ecosystems. Traditional bathymetric measurements are made by echo-sounder, a type of sonar, measuring water depth from sea surface. Nevertheless, this acquisition process ...

Probabilistic failure analysis of riprap as riverbank protection under flood uncertainties

Anton Schleiss, Eugen Brühwiler, Michael Pfister, Mona Jafarnejad Chaghooshi

Existing riverbank riprap could face the risk of failure if the flood regime changes in future. Additionally, changed sediment transport in rivers, as a possible result of climate change, impacts the failure risk of flood protection measures. Evaluation of ...
