Acceleration of Debris Flow Due to Granular Effect

Frontiers in Earth Science, 2021
Pore water pressure has been recognized as an important factor to enhance the mobility of debris flow moving in channel of very gentle slope. The creation and dissipation of pore water pressure are associated with interaction between grains.

Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

Dynamic Behavior of Bed Material around Bridge Pier under Abrupt Change of Water Pressure [PDF]

, 1999
Major failure of structures usually occurs during flood flows due to scourin, sinking and sliding. These types of failure are considered to be in close relation to the dynamic behavior of bed material around the structures.
