Recent evidence has shown that Arctic regions have warmed about twice as much as elsewhere on the planet over the last decades, and that high-latitude periglacial processes and hydrological systems are deeply impacted by rising temperatures. The stud

International audience; The Lena, a large river that drains the northern coldest region of the Northern Hemisphere, is deeply influenced by the continuous permafrost and degradation of the frozen ground has been shown to be the main cause of the mark

Impact of river weirs on bedload dynamics in low to medium energy rivers

Autor: Emmanuèle Gautier, Thomas Dépret, Frédéric Gob, Geoffrey Houbrechts, Vincent Tamisier

Assessing the impact of weirs in low- to medium-energy rivers, especially their influence on the bedload continuity, is an important issue for the understanding and management of river hydrosystems. The implementation of European regulations has for

Low-frequency passive integrated transponders (PIT tags), are commonly used for monitoring pebble mobility in gravel-bed rivers. Although early studies reported high recovery rates for PIT tags used in small streams, recovery rates in larger systems

Weirs or run-of-river dams can disrupt bedload transfer with negative ecological effects downstream due to sediment starvation. The way and the degree to which bedload is trapped is nevertheless not straightforward and few studies have examined this
