Record #112031:

An experimental and analytical study on gravity driven free surface flows of cohesionless granular media / R.M. Lang.

Title: An experimental and analytical study on gravity driven free surface flows of cohesionless granular media / R.M. Lang.
Author(s): Lang, R. M.
Date: 1991.
In: Eos : transactions, American Geophysical Union. (1991.), Vol. 72(44, supplement) (1991)
Abstract: AGU Fall Meeting Program and Abstracts, December 9-13, 1991. Four-dimensional theory is derived to describe gravity currents in attempt to model motion of dense, flow-type snow avalanches, ice and rock slides. Results indicate that model which includes constant sidewall and bed friction provides excellent comparison to laboratory findings on channel flows. For models with sideways spreading of granulate, flow transition can be accounted for by inclusion of turbulent friction term when initial inclination angle is large enough to affect boundary drag. Temporal and spatial evolution of granulate and final runout position can be predicted to values well within experimental error.
