A supply-limited torrent that does not feel the heat of climate change.

Debris-flow activity in the Alps is anticipated to undergo pronounced changes in response to a warming climate. Yet, a fundamental challenge in comprehensively assessing changes in process activity is the systematic lack of long-term observational debris-flow records. Here, we reconstruct the longest, continuous time series (1626-2020) of debris flows at Multetta, a supply-limited torrential system in the Eastern Swiss Alps.

Gravel replenishment and active-channel widening for braided-river restoration: The case of the Upper Drac River (France).

Massive gravel replenishment combined with active-channel widening could theoretically improve the morphological recovery of altered braided rivers but this restoration strategy was not yet tested in the field. A recent braided restoration project based on this principle was set up to restore a 4.2 km long reach in the Upper Drac River (French Alps) using 355.

History of bioengineering techniques for erosion control in rivers in Western Europe.

Living plants have been used for a very long time throughout the world in structures against soil erosion, as traces have been found dating back to the first century BC. Widely practiced in Western Europe during the eighteenth and nineteenth centuries, bioengineering was somewhat abandoned in the middle of the twentieth century, before seeing a resurgence in recent times. Based on an extensive bibliography, this article examines the different forms of bioengineering techniques used in the past to manage rivers and riverbanks, mainly in Europe.
