Cohesion-Induced Enhancement of Aeolian Saltation

Michael Lehning, Johan Alexandre Philippe Gaume, Francesco Comola

The wind-driven saltation of granular material plays a key role in various geophysical processes on Earth, Mars, Venus, and Titan. Although interparticle cohesion is known to limit the number of grains lifted from the surface through aerodynamic entrainmen ...

Erosion processes of a novel configuration of sediment replenishment during an artificial flood

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly

Floodplains downstream of dams with constant residual flow discharge often lack sediment supply and periodic inundation due to the absence of flood events. At the Sarine floodplain in Fribourg, western Switzerland, an artificial flood was released from Ros ...

Hydraulic Reconstruction of the 1818 Gietro Glacial Lake Outburst Flood

Christophe Ancey, Eric Bardou, Tomás Alfredo Trewhela Palacios

In the spring of 1818, ice avalanches from the Gietro Glacier created an ice dam, which in turn formed a glacial lake in the Drance Valley (Canton of Valais, Switzerland). Today, its maximum volume is estimated to have been 25x10(6) m(3). Cantonal authorit ...
